Percula Health, using WWM 10/28/05 Hello WWM <Howdy> I
have a question about the health of a True Percula Clown. I bought
the two a while back with the intentions of pairing them up. I
placed them in a quarantine tank together for about 2-3 weeks. It
didn't take long for them to pair up and eating was never a problem.
Their health was 100% during quarantine. After introduction to
the main tank, I noticed a little bump on the larger Perc, it was
located on the last white strip. So far the bump has grown double in
size, and is now turning to a light brown color and looks as if
something is trying to eat its way out from the inside. What
possible steps could I take? <Posted on WWM> Both Percs are
acting normal, eating very well, and not shy around anything. Should
I pull from the tank and go back to quarantine (they would be easy
to catch) for future treatment? I don't mind leaving in the main
tank as long has it is not a parasite that will soon be released
into the tank. Any Suggestions help as to what this is and what to
do? Take a look at the picture. Thanks Bryan <Please read here:

Hi there have got two lovely clowns, two weeks
in a 100 gallon set up one suddenly dropped into darker colour,
presuming it's just maturing although it is chasing the second like mad,
wasn't sure if it is just establishing dominance?
<Likely>
Wasn't
too concerned until yesterday where there is now on eye a perfect white
spot. Could consider a cataract, small raised circular peak, behaviour
appears normal other than being chased, both the same size the chaser
with the darkening looking a little bigger so am presuming this will be
the female.
<Likely>
Planning on treating with Myacin but could do
with advice.
<Would not "treat" at all... likely the spot is
resultant from a physical trauma... will heal on its own>
Tank
conditions normal, present with a cleaner wrasse
<Not a wise
choice... please see WWM re Labroides species>
and lemon peel all
others fine. Should I remove him to a quarantine? Can't figure out this
white spot I feel more a fungal thing doesn't look like a parasite.
<Very unlikely it is... please read through Clownfish Disease FAQs files
re.>
Ill be grateful for any help Jonathan

Clownfish Coloration - 10/13/05
<<Hello Jon,>>
One Last
question because I am definitely losing my mind.
<<I bet. Isn't this
"hobby" a blast?>>
My female Percula Clown, is very healthy and
eating actively, swimming etc. I was observing her the other day
and I saw that on her gills, (which if you look hard at are kind of
frilly looking) have some black toward the bottom. Jet black. I am
assuming that this is genetic coloration since she isn't exhibiting
signs of parasite or disease.
<<Take away her cigarettes. She is
fine.>>
Ps. My male who is in QT, is being treated with Jungle
Parasite Clear, since he wont eat any medicated food.
<<Could not
find Hex Out I assume.>>
I observed on him that he has some brownish
spots beneath his skin behind his pectoral fins. Plus, it looks like his
upper body toward the dorsal is getting a little blackish. Any more
suggestions? The packaging does not explain how long to continue dosage
so perhaps you may know?
<<I am not familiar with that product as I
tend to stay away from that brand for personal reasons. I would follow
their dosage instructions and just keep an eye on him. Let him dictate
your treatment schedule. I would suggest removing the medicated water
and replacing with water from the main display before re-medicating him
though. This give him fresh stable water while decreasing the chance of
over dose and gives the display an excuse for a water change.>>
Thanks for all you do! -Jon

Sick percula clown
- 10/13/05
Hello everyone, sorry to bother again.
<<Hola>>
First off, thank you so much for your time. You people are a godsend.
<<Blushing>>
I've attached a picture of a male percula clown who,
after being quarantined for 4 weeks, was placed in my display tank. One
month later, he has developed some strange symptoms, but his mate seems
unaffected.
He will sit almost unmoving in their anemone, unless I
put food into the water. (He is still eating vigorously) Just in front
of his dorsal fin, in what I would call his 'forehead' he has a strange
swelling, mostly along his horizontal axis, but somewhat upward also. It
almost looks like he has a marble stuck in his head. The scales over
this area stick out slightly, and the skin seems stretched, and the
entire area is slightly clouded by a thin layer of mucous or some other
light colored film. His lateral line in the area has turned rather
black.
<<Hmmm, I don't see the picture and I will need it to get you
a definitive answer. Was there any trauma to the clown? Any blood? It
there any white hairy/fuzzy outcropping on or around the lesion or is it
more of a slimy white coating?>>
The picture is bad, but I outlined
his dorsal fin and then the bulge area (which you can see the white
cloud on).
Tank parameters:
Am, NO2: 0ppm
NO3: 10ppm
Ca: 415
pH: 8.0
O2:
7ppm
The tank is inhabited by this fish's mate, a twin-spot goby, a
frogspawn coral, three rocks with Rhodactis mushrooms, two Ricordea
floridae, one cleaner shrimp, and one peppermint shrimp.
Assume this
is something environmental, I'm doing a 5% water change daily, and am
writing to ask you if you can diagnose what this is and how I should
proceed to treat it.
<<Until I see what we are talking about I would
not worry too much. Feed him well and keep the water maintenance up and
it will hopefully clear on its own. Most fuzzy white head bumps do.>>
Thank you very much, Benjamin Kratchmer

Clownfish - 10/12/05
Hi Bob and guys :)
<<Hello, TravisM
here.>>
I had emailed you a while ago about my yoyos "odd behavior"
and you guys put me at easy with their weirdness. I've been enjoying
them ever since and they are all still living and doing well.
<<Glad
to hear that.>>
I have since started a saltwater tank that has been
up and running for a few months. I have a true perc and a dwarf pygmy in
there that I have had for about 3 weeks. My fish store is a mom and pop
place and they had the true perc at their store for 6 weeks before I
took it home. It was their pet. (I had bought a false perc but it died..
the whole batch did.. bad batch so he gave me the true one).
He has
been eating fine and doing very well. Both fish get along great and
surprisingly swim together a lot.
Yesterday, I noticed the true perc
had some white stuff on it. It's not ick I don't think, it's more like a
patch of dry skin on his "forehead" and on his side.
I've been
reading a lot and I've read through your pages on clownfish. He has also
started doing something he has never done before. I have the return in
the middle of the tank and 2 power heads, one on each side. It's a 55g
by the way with live sand and live rock, 20g sump underneath, skimmer
etc. He has been swimming upwards where the current meets, in the middle
of the tank. He'll do that a while and then go and swim normally around
the tank and then go back there and swim upwards.
This morning, I
turned on the lights and he was laying on the sand. I don't really know
what he does the other mornings but I don't remember him laying on the
sand. It's too early for me to think about it and I'm usually in a huge
hurry, running late as always. I fed him to see if he would eat
but he didn't really budge. I finished getting ready and then by the
time I left, he was swimming around the tank.
I noticed that the
white on his side is gone, his color was good and on his forehead, it's
almost gone.
I also have some polyps and some zoos in there.
What's wrong with him? Is the behavior normal, swimming upwards?
<<Lets hope nothing. Yes, they are clowns and do some crazy things like
swimming into powerhead currents. I call it their treadmill workout.>>
What could be causing the white patches? I thought of marine velvet but
I was unable to find pictures to compare and I'm pretty visual but it
doesn't sound like it would be that.
<<Fish can get some weird benign
things that spontaneously go away. Do keep an eye on him though, if you
notice rapid breathing and the white patches look like the slime coat is
coming off odds are that your clown has brook (clownfish disease) and
you will need to treat him and the angel with formalin immediately.>>
Oh ammonia, nitrate, nitrite were 0, salinity was 1.025, temp was 82.
Sorry this was so long and thank you!!
<<TravisM>>
Sick
Clown!!! - 10/15/05
Well,
Here's the sick clown update. Last
night at 7:00 I put a fourth of a Jungle Parasite Clear Tablet in the
2.5 QT tank. He pretty much acted the same. However earlier in the
day, he developed brown or black marks under his skin behind his
pectoral fins and it looks as if he is blackening along his lateral line
and it does not look natural. He did at one point begin flicking at the
bottom of the tank on his side.
So anyway, put the stuff in last
night. Sat all the way up until 3:15 today when I got home and found the
water very cloudy and filled with stringy slimy stuff I take is his
mucus. It all gathered around the airstone. So I changed all the water
and gave him fresh water with no medicine in it right now. (just
finished).
<<Good idea.>>
I'm not quite sure what to do next,
being I don't want to OD him on Metronidazole.
<<Have you noticed
changes with appetite or feces?>>
Really don't want to put the Quick
Cure in either since I really don't see any specks on him.
<<Good
idea. Never blindly medicate.>>
Nor do I see anything that looks like
velvet. His eyes are still clear, but he still won't eat anything.
<<Have you been trying different foods? Frozen brine or Cyclop-Eeze?>>

Sick Clown Follow-up 10/15/05
Cool, Thanks again.
<<Glad to help.>>
This is quite the hobby. And
I thought I would not exceed 300 dollars. HAHA.
<<Now that is
funny... I don't care who you are!!! I about fell out of my chair, but
it is an all too common misconception. Fish tanks aren't cheaper than a
dog or cat. They are just quieter and less hairy.>>
Do you think you
might know what these spots behind his pectorals are??
<<Not 100%
sure on that. Hopefully the external meds will clear it up. Clowns can
also get melanistic spots, kind of like a rash, from brushing against
corals.>>
He actually is starting to flick the bottom of the tank :(
<<No signs of ich?>>
I really am not sure what's going on! There are
under the skin, so it's not ich, but ahhh. The Parasite Clear has the
Metronidazole in it and says it cure external and internal parasites. So
what's your take on this. I don't want to add any quick cure to the
tank, or do you think I should.
<<Never mix meds. For your fish or
yourself... Always treat the major issue first and then work on the
smaller ones.>>
This poor fish. He must beat this!
<<Keep your
chin up, keep his tank clean and he will have a good shot at it.>>
Thank Travis.

Re: Perc loss
10/20/05
Crew,
<<Jon>>
I want to thank Bob and Travis for
the help they offered me while trying to treat my little Percula
Clownfish with an internal parasite. Unfortunately, he has lost his
color tonight, and is swimming around the surface so Am sure tonight
will be his last night. :'( Thank you for all your help and all you do.
It is truly appreciated.
<<I hope this email finds him well. It is
always hard to lose a fish when you know you have tried everything.
Unfortunately, it is part of the hobby. The best thing you can do is
learn from this and move forward. I hope our advice has given you many
tools to use in the future and I wish you luck.>>

Clownfish with internal parasites, medication -
10/15/05
Good news.
<<About time... :p>>
I got my hand on
some Piperazine.
<<That is good news. That stuff has been very hard
to come by in the aquarium trade.>>
I put a little bit into the tank
(because its only 2.5 gal and 1 capsule treats 10gals.) After I did a
total water change from the other crap.
Let's hope this stuff works.

Clownfish diseased
10/5/05
Hi, I've been having a great time with my first
(50-gallon) saltwater tank. All the water parameters are perfect
(8.0/0/0/0). 50# LR and 4" bed of aragonite.
Our two ocellaris
clowns survived quarantine for two weeks and have been doing well in the
main tank for another two. Last week we added a bubble tip anemone; the
smaller clown has taken to it nicely.
Today I've noticed an
approximately 2 mm light brown circle on the hindquarters of the smaller
clown. He seems less active but is still flapping his fins. Still
upright, breathing OK, no other pathologic markings as far as I can
tell. The other clown is doing well.
We're getting the QT ready
again... needs bleaching though because a clownfish recently died during
quarantine. It'll be ready tomorrow night. What do you think's going
on?
<Nothing>
Should I be getting my hands on any medicines in
particular?
<Why?>
Should I perform a freshwater dip
(and if so, when)?
<I wouldn't>
Thanks so much
Daniel

Re: Clownfish diseased 10/6/05
Bob,
Thanks for your response, and in general for being such a wonderful
resource.
<Welcome>
Unfortunately I got up this morning and the
smaller clown was flopping about uncoordinatedly. His color had faded
dramatically and it looked like he had a whitish thin film all over him.
<Yikes... not good>
There were nips taken out of his tail;
these I suspect were from the bigger clown, who usually was all chummy
with him but now was attacking! Aiming to avoid infecting the big clown
with whatever the little one had, I removed the poor little clown and
sent him to his septic grave. The big one looks OK so far, but I'm
going to watch closely. Everyone else in the tank (inverts) looks good.
Any idea what could cause such a drastic and sudden decline in the
little clown's status?
<Need to ask a bunch of
questions, know related items in turn... are these wild-caught fishes?
Were they quarantined? Do you know what Brooklynellosis looks like?>
Do you think I should be worried about the other clown, and if so do you
have any suggestions regarding action(s) to take?
Thanks so much
Daniel
<... have you read over the materials on Clownfish on WWM?
Please do, and quickly. Bob Fenner>
Re: Clownfish diseased 10/9/05
Bob,
I read WetWebMedia a lot.
It's great.
To answer your questions:
Tank raised. Quarantined
for 2-3 weeks. I looked at some pictures of Brooklynellosis on the Web;
I suppose the film on the dying clown did look a bit like that... but
none of the pictures was really clear. Anyway, the other clown
appears to be doing OK.
<The slime on the dead one could be "just"
from stress>
He has always liked to stay near the top of the tank,
and is still doing that. He's got no spots on him and yesterday he ate
immediately upon feeding. There is no other fish in the tank (just
inverts). Given that he's the same species as the dead fish, would
you recommend empiric quarantine? Or can I just watch closely?
Thanks
so much
Daniel
<The latter. Bob Fenner>
A
Ocellaris - trouble with a move 10/5/05
My fish were
stressed by a recent move. Can you help?
<We'll see>
I moved my
46 gallon bowfront tank to a new house last Friday. The livestock and
live rock was out of the tank and in transport bags for a little less
than two hours. I moved most of the original tank water in buckets and
added about 15 gallons of "fresh" salt water so that I wouldn't have to
add any of the water that the livestock had been transported in to the
tank.
<Better to add this water... if not too polluted>
I've
tested nitrate, nitrite etc. daily since the move and found the water
conditions to all to be undetectable or very low, the same as before the
move.
On Sunday afternoon a noticed my female Ocellaris swimming
midlevel in the tank, which was odd for her - she usually prefers the
top. By Sunday evening she was laying on her side at the bottom
gasping. I put her in a five gallon with some of her original tank
water and an airstone - later that evening she started getting a white
"fuzz" on the inside of her mouth. My LFS suggested dosing the tank
with iodine (the suggested does for a reef tank of Kent) and treating
her with tea tree oil,
<Worthless... I wish AP would pull these
placebos>
but by Monday she died and the white "fuzz" had spread all
over her mouth.
<Opportunistic, secondary...>
I've been checking
her mate for symptoms and found the bicolor blenny laying at the bottom
of the reef tank gasping. I can't see any of the "fuzz" on him/her yet,
but... I know it is hard to give advice from a description over an
e-mail, but what would you suggest to treat this fish with?
<Mmm,
nothing... perhaps vitamin addition, soaking foods in same>
Should I
go ahead and treat the male ocellaris even though he seems to be doing
well? Other than the bicolor blenny and the remaining ocellaris there
is a diamond goby and a Kole tang in the tank.
<No>
The
Ocellaris had been with me for a year (female) and eight months
(male). The bicolor blenny about three months and the goby and tang
were the newest additions, from just over a month ago. Until the move it
looked like I had a bunch of happy healthy fish.
Thank you for your
time!

Tomato Clown Behavior 10/4/05
Hello Crew,
Thank you for
your very useful info regarding my Featherduster. He's looking mighty
fine these days. But I have a question about my tomato clown.
I
have 120 gal, lots of live rock and sand, some coral, a percula clown,
yellow tang, sleeping goby, eyelash blenny, a couple of damsels and some
hermit crabs. When I got the tomato, he did all of the usual tomato
things: commandeer the anemone away from the percula, chased away
anything that came near the food, etc. His "fondness" for the anemone
killed it.
<Well-stated>
Since then, he's just been swimming
around like normal. All was well when he just "disappeared" one
day. He was out of sight for 2 days then just appeared one morning
looking pretty beat up. I have no idea where he was hiding, but his
little wounds looked like abrasions (maybe he was trapped?).
<Possibly>
Anyway, he was acting just like normal and eating like a
pig. In the last couple of days he's been swimming strangely. He kind
of hovers in position with his head pointed straight up, kind of like
he's standing on his tail. He'll do that for awhile then start swimming
around like normal. Then he hovers again then starts swimming like
normal again. Is this normal or is he feeling ill? Thanks in advance
for your help.
<Very good description... it does sound like this is
a wild-caught specimen that is internally parasitized (very common)...
it may cure on its own (doubtful), or you could attempt a cure... by
feeding it foods laced with Metronidazole/Flagyl, and possibly a
vermifuge if it's eating... these compounds, use, are covered on WWM.

Percula clown lip/face rot 10/3/05
We purchased three percula clowns at the same time, one has something
horribly wrong with his lips/face. It looks like his face is rotting
away. It started with his lips and is slowly spreading (rotting) away
more flesh. Is there anything that can be done for him? We have
quarantined him.
<Perhaps an antimicrobial/antibiotic treatment
(through the food if the fish is eating), an immersion bath if not...
Likely resultant from fighting damage on placement, by the other
"pair"... Bob Fenner>
Anemonefishes and furans 9/30/05
hi, Bob :)
When you have a chance... do you recall mentioning in CMA
or on WWM that Anemonefishes were sensitive to Furans?
<Mmm, no...
as a matter of recent experience, saw new wild-arrival Amphiprionines
being treated with such at SDC... last week when I was
visiting with
Karl, EricC... delivering NMA bk.s...>
Steve Pro pointed to a BB
thread where someone recited it and drew flak for it.
<Mmm, I'll cc
Steve here... am sans ref.s out in HI... but would check Noga... BobF>
We are looking for sources/experiences to support it.
grazie!
Re: Anemonefishes and furans 9/30/05
Noga simply says that
in general Nitrofurans are carcinogenic, genotoxic, and
mutagenic. Additionally, catfish, loaches, and other scaleless fishes
are sensitive, but nothing regarding Clownfishes specifically.
I
believe the questions came from this article,
http://www.wetwebmedia.com/clownfis.htm
"C) Chemicals: Last and
least. Be careful. Clown fish are like "canaries in a cave". They tend
to be sensitive to the same toxins as their host actinarians (anemones).
Copper, other metal salts, organic or metallic dyes, furan compounds,
and organophosphate pesticides all have deleterious to disastrous
effects. These substances in various formulations, comprise most of the
"medicine treatments" available and used in our aquatics interest.
They do have some limited, appropriate applications in bare marine
treatment tanks. 'Nuff said?"
<Mmmm, must have believed/read this at
some point/place... do agree that Clowns shy on the more sensitive than
average side (often related to organisms that cross phyla in symbioses)
of fishes... Am out in HI, or I'd try to find where I got this. Cheers,
BobF>
Clownfish sick... aquarist ignorant 9/29/05
So much
for a healthy happy clownfish. My clownfish has some white stringy
stuff coming out of his underside. A cottony coating starting to grow on
him and he does not look to good the other one is fine. bottom fins are
tucked in. The pet store gave me PimaFix.
<Worthless, correction...
worse than worthless>
My water quality is great they said for a 6
gallon nano No nitrates etc.
<... this system is too small for
keeping this/these fish>
The sea spider
<... what?>
is
sitting on the rock reaching out for the fish I guess waiting for a
meal. I think it's a spider lat white with 5 white tentacles with red
tips???? Anyhow what can I do to save the fish?????

Sick clown follow up: 10/3/05
You guys are awesome thanks
for answering all my questions. I am obsessed with your site but sad to
say my clown has passed and my daughter thinks I flushed him to the deep
blue. The culprit clown that I did not QT that got my other clown sick
is still not eating and now has stringy poop. I am too much a novice to
try and save him. (Particularly cause I think it's Brooklynellosis only
because after the fuzzy stuff fell off, my other clown had a red
ulceration on him.)
<Can/could be treated with one go with
Metronidazole/Flagyl>
Question is how long do I leave tank empty so
whatever it is can die.?
do I change filters bioballs etc.?
<... no>
Will inverts carry disease or parasites?
<Can, but
unlikely>
what about live rock?
<Ditto... leaving the system
fish-less for a month will likely "solve" any pathogenic problem>
Unrelated------- also what are the flat white things that slide around
on 4-5 tentacles they are carnivorous I think.
I have a few, worried
they are parasitic or such.
<Highly unlikely that these are
parasitic... could be worms, crustaceans, cnidarians...>
When
first clown was dying they kept trying to get a hold of it?
<What?>
may be unrelated. I promise to dip new fish in PH adjusted water when I
figure out how to adjust PH? I use R/O water do I still need to adjust
it???
<Maybe>
Enough questions for now. the little guy is
hanging on I wish I could help him.
Thanks again guys and the LFS
guy told me he never heard of Brooklynellosis and that I was reading too
much on the net!

true Percula 9/28/05
<Please... the beginning of sentences
are capitalized, proper noun "I"... Percula...> hi, I purchased three
false percula's recently and I had a very bad incident. when it came
down to it, one was actually a true Percula (the smallest of the 3). I
had them in a 30 gallon with only one other fish a sixline wrasse, 5
snails and 5 hermits,
<Too crowded...>
1 RTBA, hammer and a fox
coral.
<Incompatible... my friend. You're setting yourself up for a
disaster. Please research the needs, compatibility of livestock before
acquiring it...>
I have been cycling a 60 gallon for about the last
3 weeks with about 90 lbs of live rock, 2 green cromis, 10 snails and 10
hermits. yesterday I transferred the pair of false to the bigger tank,
<Ah, good>
they are doing fine. my smaller clown has 2 bumps on each
side of his first stripe and this slimy film (stress????)
<You are
likely correct here>
he refuses to eat. my wrasse is a pig. I went
to look at him and I have noticed that he is swims in one part of the
tank, very lethargic. my parameters are excellent nothing out of range,
I do a 10-15% water change weekly. what am I doing wrong?
<... too
many possibilities to delve into here... Please take your time, read
over the set-up, maintenance articles, Clownfish Disease, as many of the
FAQs files as you deem necessary... on WWM. Do you have a "complete"
marine aquarium book? You might gain insight from a cursory re-reading.

Re: Sick Percula 9/30/05
I apologize
for my grammatical error, I didn't realize it was that important.
<Sometimes... mostly as "object lessons" for all... but also for clarity
of communication>
I have a 2 year old that was trying to get my
attention. I do have a question regarding my pair of false perculas,
ever since I moved them to my 60 gallon tank, the female has a slime
coating. She is active and eating. Again, I think it's stress.
<Agreed>
I think that it may have started when I removed them from
their host anemone. Can you tell me your thoughts? I am only 3 weeks
into my cycle and I refuse to move the anemone to the new tank for about
another 2 weeks.
I do love your site, it's very informative.

Internal parasite? 9/24/05
Hello there, just one quick question. I have 2 True Percula clowns in a
90 gal with a Kole tang, 2 Banggai Cardinals and 2 skunk clowns. There
is no fighting at all. Ammonia and Nitrite 0, Nitrates 5ppm, Ph 8.1 in
the morning 8.2 in evening. Anyway, my question is about the
Percs. Three weeks ago I noticed a white string of feces trailing from
one of them, and a few days later, the other one had the same. They
were both feeding, swimming and acting normally, with no rapid
breathing. They also had no external symptoms of anything wrong. I
quarantine all of my additions to the tank for 8 weeks, as I am choosing
to learn from other's mistakes. No fatalities so far!
<Congrats...
you're in the superlative minority>
I asked my LFS and read on
WWM, and I came to the conclusion that perhaps they had an internal
parasite.
<Mmm, unlikely>
Hard to really believe though, as they
are both rather plump and have grown to 1.5" from <1" since I purchased
them 5 months ago. I quarantined them after this 'diagnosis' and
treated them by feeding Anti-Parasite medicated fish food for internal
parasites by Jungle Labs, as per the instructions. While I did this
medicating, they had no white feces, and they continued to umm 'go'
normally for the next week (treatment consists of feeding only the
medicated food for 3 days, then regular for 4). I chose to treat them
for only 1 week as opposed to 4, because they began to be more lethargic
in the QT, and I'm still not convinced that they even had a parasite.
<Good>
After acclimating them back to the main tank, the perked
right up again, and were just as before... including the white poo!!! So
I guess my question to you guys is this: considering all this, and that
no other fish have this, could this be nothing more than a digestion
thing?
<Yes>
I rotate green seaweed flakes, Mysis, brine, squid,
krill and pellets...please help!

worry. Bob Fenner>
Sick Onyx Clownfish and Calcium/Alk
9/24/05
Hello Crew,
I have a sick Onyx clown that I have had
quarantined for over a week. I looked on your site and tried to find out
what the little guy has but really to no avail. About two weeks ago his
mouth started to hang open and he looked stressed so I placed him in the
quarantine tank with copper so my other clowns wouldn't be exposed to
him.
<Will/would affect all if biological, pathogenic>
After a
week of quarantine he really didn't look any better and some kind of
white lump formed under his mouth, so I have been giving him a daily
freshwater dip with formalin-3 cause I thought it was clownfish disease.
<Uh, no... the lump likely "just" stress, the move, treatment>
He
started to look better but the lump has come back and I am wondering if
you guys have any clue as to what this is. He also isn't able to close
his mouth, kind of looks like he has something holding it open but of
course nothing is there.
<Most likely genetic (defect)>
I am
worried cause as you know this is a rare and expensive clownfish and I'd
hate to lose him. He doesn't seem to be breathing all that heavy but he
doesn't really go for food either. Should I just continue with the
freshwater dips with formalin and hope?
<I would move the fish back
to the main tank and hope>
I was also thinking of lowering the
salinity in the quarantine tank. I have 4 clowns total, 1 onyx who is
this ones mate, and two percula clowns and they all seem fine eating and
swimming, so I am assuming I got the sick one out in time to avoid
further damage thank god.
One more question if you don't mind, my
tank is a 46 gallon reef tank which has been setup for 3 years, but I am
having a heck of a time raising my calcium level which is about 200
meg/l.
<Please read on WWM re calcium, alkalinity, replenishing live
rock in aging systems>
The alk level is off my charts and my test
only reads to 5meg/l which is the norm, I'd say mine level is almost 10
meg/l!!!
<...>
I have read on your site that the calcium and alk
level are always opposite each other (one low one high).
<Good way
of putting this>
My corals and the coralline algae are spreading and
look fine but I want to get the alk down and the calcium up to 400
meg/l, and I can't afford or have room for a calcium reactor. I add
liquid calcium just about every day following the bottle directions and
the level always stays at 200 meg/l. When I add the calcium my corals
close, I am assuming that this is bad.
<Yes>
I am thinking that
when i add ph adjuster (about once a week) the alk level keeps going up,
keeping the calcium level down.
<A clue here>
The coralline is
growing all over the back of the tank, rocks, powerheads, and overflow
and even some in the refugium, so I am debating if I should even mess
with it cause the tank seems very stable and don't want to start
stressing it out but I could be wrong on that.
My levels are
ph
8.2
alk 10 meg/l (estimate)
ammonia 0
nitrite 0
nitrate
0 to 5 ppm
cal 200 meg/l
magnesium 1300 meg/l
phosphate 0
<Mmm, the coralline are taking up available calcium, you're likely out
of balance with magnesium... you're bolstering alkalinity....>
Here
is my live stock:
the clowns
1 yellow tang
1 painted fairy
wrasse
1 sandhopper blenny
1 neon Dottyback
2 peppermint
shrimp
1 huge cleaner shrimp
approx 50 lbs of live rock
4
inch crushed coral/live sand bed
1 pink leather coral
10 red
zuma mushrooms/ 5 fuzzy mushrooms
about 3 zoanthid colonies
1
torch coral with about 5 heads
1 frogspawn coral with 4 heads
1
Alveopora (not doing to well)
1 cool neon orange plate coral

True percula clown
with suspected HLLE disease 9/22/05
Good morning to whom
ever responds. <Good morning Lucas> I have just noticed that my true
percula clownfish has a very small pit on the top of her head. It is
very recent and did not notice it a week ago. I feed my fish
Mysis shrimp daily and use flake food 2 times a week ( she eats like a
pig ). All of my water parameters are good, SG 1.024, Ammonia 0,
nitrites 0, nitrates 0, I do not test calcium as I do a 5 Gallon water
change each week (30 g tank). I do not think it is stray voltage.
<Won't know without a test> I have just ordered Selcon from my LFS and
they tried to sell me some garlic extreme product. Can you use
fresh garlic to achieve the same effect? <No, the concentration is much
lower in Garlic Extreme.>What are some known food additions I
can add?<The Selcon is a good one, look no further> I believe that my
fish might not eat enough algae, what are some good algae's that my
fish may eat? <The fish you have aren't really algae eaters.> Are there
alternatives to algae that might be easier to obtain at my local
grocer? <Sushi Nori at the gourmet department> Can it be my corals
causing stress? <Unlikely unless they are dying.> Current invertebrate
inhabitants are, 2 green bubble tip anemones, a green tipped
torch coral about 300 various zoanthid polyps and 3 types of mushrooms,
and metallic green star polyps. Fish are, 1 large green Chromis, the
sick true percula clown, 1 spotted mandarin, and a mated pair of yellow
tail damsels. My clean up crew is 10 blue leg hermits, 4 turbo snails,
and 1 Sallylightfoot crab. My equipment is 1 marineland 300 series HOB
filter, 1 red sea Berlin airlift in tank skimmer, and 2 zoo med power
sweep 220 gph powerheads. and 20 lbs of Aragocrete and 24 lbs of pokeni
live rock. The only thing I do not have, is a RO/DI water filter. Am I
missing any thing you can think of, as far as equipment I may need? I
appreciate ANY and ALL advice that the staff at Wetwebmedia
can provide. <I'd google the WWM, keyword, "maintenance" and read
there. James (Salty Dog)>
Thank you,
Lucas in Denver
Stressed or diseased Clarkii 9/22/05
Hello Wet Web, Bryan
here <James here> with a question about my Clarkii and Long Tentacle
Anemones, but my tank setup:
55gal, crushed coral substrate, 40lbs
of live rock, Seaclone 100 skimmer, 330 BioWheel, MaxiJet 900 powerhead,
2 ea 110 VHO bulbs (1 Actinic 03 Blue and 1 Aqua Sun white)
Fish
include a Clarkii Clown, Purple Anthias, Yellow Tail Damsel, and a small
Yellow Tang (Tang will go to a big tank when he gets bigger), Other life
forms are a beautiful blue LTA and a Green/Purple LTA, 12 hermit crabs
and 1 emerald crab
Water conditions Ammonia-0, Nirite-0, Nitrate-10,
Salinity-1.022, Temp-77
Alkalinity-260 to 280, pH 8.5, and
calcium-500.
Hope that sets the stage. First, I had a T/R Percula
Clown but from the moment he was introduced he did nothing but tread
water at the bottom front part of the tank, did not eat, developed white
spots and died,<sounds like no QT used here.> never going to the top and
gasping for air. The white spots and death occurred with a 24 hour
period. At the first sign of the white spots on the Percula, the
clarkii stopped eating, and started to tread water and breathing
rapidly. Later on I added my LTA's that were on the way. I placed the
blue one on a rock and he took to it very well, as did the Clarkii after
5 hours. Since then the Clarkii has not left the LTA for past 2 days
and is still not eating. I did notice a small bit of slime hanging off
him, NO white spots, and his breathing is still rapid. What is wrong
with my Clown? <difficult without seeing. Could be producing the slime
coat needed for protection from the anemone's sting.> As for the blue
LTA, he has moved, but has not attached to anything, just resting on the
bottom fully open. The green/purple LTA, is having a rough time, he
can't seem to get settled, and looks like he is trying to hide in
between rocks. Is that normal for a LTA? <Upon introduction, yes> It
did have some shrinkage, change in color, and expelling left over food,
but now seem to be a normal color, just not settled in. Should I be
concerned with the LTA's not settling down and attaching to
anything? Just one more thing kind of off the health subject, is there
something I can do to keep my Seaclone from sending tiny bubble back
into the tank? <need some sort of bubble trap, even a piece of sponge.>
I have tried to adjust it for 3 weeks now, and can't get it to stop
filling the tank with tiny bubbles. <Your anemones won't be around much
longer with your current lighting system. No where near enough
light. See lighting and anemones on the WWM. James (Salty Dog)>
Thanks, Bryan
By the way, you have an excellent site for
information! <Thank you>
Killer of Percula Clowns
9/21/05
Hello Crew, <Hello Doc>
I have written in the past
regarding my reef tank (120g), I have a question about my second dead
percula clown. I have several other fish (hippo tang, yellow tang, flame
angel, 2 fire fish, orange spotted goby, black blenny, royal Gramma, and
a percula clown) they are all doing very well. I had a second percula
clown that stopped eating, became very thin, and then subsequently died.
I placed it in my sick tank and tried to treat it with Maracyn. Needless
to say it did not work. It did not have any plaques on it, ich spots, or
other noticeable changes. I am concerned because this is the second
percula clown I have lost in about 2 months. The other clown (that is
still alive) I have had for about 6 months and has been doing very good.
Is it something I should get VERY concerned about or chalk it up as a
percula clown thing? The other critters in my tank (several corals,
shrimp, and clams) are doing very well. <Weekly/bi-weekly water changes
help the overall health of fish along with a good diet. Wouldn't be too
concerned, were they tank raised? They seem to fair much better than
the trues. Any harassment by other fish? James (Salty Dog)>
Dr. M
Killer of Percula Clowns
Thanks James.
I do 10% water change
every 10-14 days. The other fish in the tank did not
seem to harass
the clown, even while it was sick. I purchased it from my LFS
and I
have to assume it was tank raised. <Doc, I wouldn't assume that it was
tank raised, could be the wild variety. Sounds like the death of the
clowns can't realistically be traced to anything, just one of those
things that happen in this hobby. James (Salty Dog)>

Clownfish with Cauliflower Growth 09/17/19/05
Dear
Crew: HHHEEEELLLLPPPP! I noticed a growth on my large 2" clownfish. I
have him quarantined and have medicated with Furacyn for 3 days with no
results. The growth is on the left lower side of his "chin" and looks
like cauliflower. It is a dull white. The clown acts normally, is
eating like a horse, swimming and nuzzling his anemone. Can this be
treated and is this the proper course of action.<<Quarantine is the
correct 1st step. The growth could be Lymphocystis. If it is
lymphocystis, it will sometimes cure itself with improved tank
conditions. Please see this FAQ (http://www.wetwebmedia.com/lymphfaqs.htm)
and search WWM for "Lymphocystis". Good luck - Ted>>
Fiendish
Firefish? Unquarantined Clown - 09/03/2005
I have a well cycled
(6 months) reef aquarium (keeping a Mandarin and Firefish with no
problems- I
<PLEASE, everyone - capitalize your "I"s! We have to
fix these errors, you know. Takes forever.>
breed Copepods for the
Mandarin in separate culture tank).
<Just be sure it's enough to
keep the fish fat and happy.... Easier said than done.>
The tank is
only 30 gallons but I thought I should be able to keep about three fish.
<Smallish, peaceful fish, yeah.>
I just bought a false percula
clownfish and it died 2 days later :( The fish never seemed to be able
to swim upright from the time I acclimated it and the fins deteriorated
(or seemed to be tattered).
I am wondering if the purple firefish I
had may have damaged it (when the lights were out as I never saw any
aggression during the day)?
<Whaaaaat?? You didn't
quarantine the clown? I mean.... that's a sure invitation for
disaster.>
I know mandarins are not aggressive in this way, but
before I get another clown, I would like to be sure the Firefish wasn't
the cause.
<It is very highly unlikely that the firefish had
anything whatsoever to do with this. Just hope the clown didn't die of
something communicable which has by now passed to the other fish in the
tank.>
Thanks for any info. I think I just got a fish that had been
moved too many times- the LFS store had just brought them in the day of
my purchase.
<Your next purchase really ought to be a small
quarantine system. It will save you money, time, grief, and work in the
long run.>

<Wishing you well, -Sabrina>
Fiendish
Firefish? Unquarantined Clown - II - 09/07/2005
Thanks for the
reply.
<Of course.>
While upset about the loss, I (capitalized)
<YAY! Thanks.... Really!>
am unable to keep a quarantine tank at
this time having only a 30g with fish stocked from the same store- all
of the LFS's tanks run off of a single large filtration unit behind the
display so I didn't think much of it. This was probably stupid as every
new batch of fish they get could bring in a new disease (smacks self).
<Yup. You got it. And since ALL the tanks are run off a single
filtration system, if ANY fish in the store has ich.... then
potentially all have ich. See? Quarantine Is Good.>
Frankly, a
quarantine tank would be almost as large as my main- and I'm moving to
my first house in about 1 and 1/2 months.
<Ahh! Congratulations!>
I already have 4 tanks to move ranging from 60g down (all others are
FW).
<Believe me.... I feel your pain....>
I
understand the reasons for a quarantine tank and will wait until I can
set one up at the new place rather than just replace the fish.
<Very, very good. This will save you time, money, grief.... life....>
Hopefully it was just stress rather than disease :/ I'll be watching my
tank closely for a while.
<A good plan indeed.>
Thank you for your time. I just wanted to be sure a firefish is
non-aggressive to clowns as some as the advice I have received from my
LFS is suspect (sure a mandarin will be fine in a 30g with live rock-
you don't even have to feed it).
<The firefish should be perfectly
compatible. I do hope your copepod farm is very productive! Wishing
you and your fish well (and thanks for the
punctuation/capitalization!), -Sabrina>
Help with Clownfish...
induced health troubles 8/18/05
First off, thank you again for
the advice on my previous question. I have since run a full treatment
of Formalin
<... formalin>
on my 55 gal. system, performed a 30%
water change, and purchased 2 more false perculas (1.75 - 2 inches in
length) from my LFS.
<... this size, not likely captive-produced...>
I did check with the owner about the specific gravity of his tanks
(1.020) and now have my tank matching that. Nitrates are nonexistent,
Nitrites and Ammonia are very low,
<... should be zero>
pH is
roughly 8.0, and the temperature ranges from 78ºF to 86ºF
<... too
much vacillation>
(during the day with lights on) - yes, I'm
thinking I need to get a chiller unit. The lighting is a 300W JBJ
compact fluorescent, 2 actinic bulbs run for 8 hours and the 2 daylight
bulbs run for 2 hours. I am feeding the clowns frozen Mysis shrimp,
Spectrum pellets, and soon live brine shrimp (waiting on the first
hatching now). I am treating all the food with Seachem's Reef Plus
Concentrated Vitamin and Amino Acid Supplement every several days.
These two fish seem a lot healthier and more energetic overall (I've
even seen the male "stutter" for the female while they were playing
"tag"). Both are eating 2 - 3 times a day, (in the small amounts I feed
them). My concern, after the last fiasco, is that I have noticed some
small spots on the male.
<... you didn't quarantine...>
I've
seen Ich before, and I don't feel that's the case here, these are small
gray spots on the fish... about the size of a scale. He has one on one
side and 3 on the other (2 near the front dorsal fin and 1 near the rear
of his back fin). The male is the only one with these "dots," and none
of them are pronounced, or raised off the skin like I have seen Ich do
in the past. As I mentioned, both fish are eating, swimming around the
tank, interacting with one another, and are very vibrant in their
coloring.
I'm hoping that this is nothing,
<Maybe>
I'd rather err on the side of caution after losing the last four clowns
I had within a weeks time (before the tanks Formalin treatment). Again,
thanks for any help that you may be able to provide.... and keep up the
great work with the website.

Occasional
stringy feces for months 8/15/05
I've had my ORA captive bred
female black ocellaris since early January. To this day she and her ORA
captive bred male counterpart (which I've had since late March) have
show signs of stringy feces. They don't display it everyday, and they
have had various types of feces (e.g., powdery reddish
brown, to a
clumpy brown, brown and stringy, and stringy and white).
<Could be
the food...>
When they were in my display I fed them Spectrum
Thera-A pellets, Mysis with garlic and Mysis with Metronidazole (for
three days)
<I would not repeatedly expose fish livestock to this
anti-protozoal>
in their food, and Pepso food per directions
indicated on the package. None of these foods/medications made the feces
consistent (still white and stringy on occasion). Early on, I also gave
the pair several months of doing nothing (treatment-wise) to see if it
would clear up on its own.
<Mmm...>
They have been in my 10
gallon quarantine tank twice for the months of June and August (In July
I moved them back to the display to see if it was a water quality
issue). In June I treated with two cycles of Pipzine in the water, and
one cycle of hex-a-mit,
<Also Metronidazole>
also in the water).
In August I treated them with PraziPro and saltwater Maracyn two in the
water (per package instructions). Note that in between each type of
medication I ran carbon for at least 48 hours and did a 50 % water
change to avoid mixing meds.
They have been very active this whole
time, utilizing all levels of the reef (I have even observed the female
biting on rocks). Their breathing is normal, and they have clear eyes,
great color and fins are always erect.
They are, and have always
been hearty eaters, being fed 1-3 times a day. The female and male have
also grown considerably (~1inch) since January and the female's face has
gone from a bright orange to almost completely black. If they did not
have the strange feces I would consider them perfectly fine.
<They
are likely "perfectly fine"... will not be if continually handled,
"treated">
They are fed frozen Mysis, frozen Spirulina enriched
brine shrimp, formula 2 pellets, formula 1 flake, spectrum Thera-A
pellets, Hikari marine-S pellet, steamed broccoli flower tops, and
Cyclop-eeze.
<Wow! I want to live at your house>
All foods have
been soaked in Zoe (heavy Spirulina formula) and Zoecon and sometimes
garlic. I don't think
it is a diet issue, because my gold stripe
maroon clownfish is fed the exact same items and does not have the same
feces.
<Different species>
The parameters in the display:
Amm: 0
Nitrite: 0
Nitrate: 0
pH: 8.2
salinity: 1.026
temp: 80-81
The 10 gallon quarantine tanks has the same parameters
except the salinity is ~1.024 and the nitrates may creep up to no more
than 5-10.
I have tried to contact some research institutions in my
area for examinations. These include; Florida tech, Harbor branch, ORA,
and have had no luck. (Harbor branch and ORA are about 20 minutes away
from my house and i would be willing to drive there and pay for a fecal
examination).
I really like these fish and want them to live a long
life and eventually breed. What should my next move be? Move them back
to the display? Keep them
in QT longer? Any suggestions welcomed.
Thanks,
Bryan
<I would re-place these fish... very likely there
is nothing wrong with them... Bob Fenner>
Ill Clownfish 8/6/05
Hello again Crew!
Thanks in advance for your help.
Four days ago I bought a mated pair of percula clowns, and after
36 hours I fed them. The male would not eat, only go up to food and
look at it, but the female fed well. The male began to defecate, but
produced a green stringy matter, which trailed behind him for several
inches and slowly lost its color, but still left a hanging residue.
This morning, both fish are displaying this symptom, and the female
has white mucous flaking off her in several places, and seems to have a
light glaze of this over her whole body.
Assuming the worst, I'm
giving them a formalin dip to treat possible Brooklynella, but am
wondering what to do about the eating and pooping. Is this a side
effect of the protozoa, or is it internal bacteria?
<... likely
neither>
I was unable to find the crew's recommended Spectrogram
or Kanamycin <Likely Kanamycin. RMF> at any LFS, is there a substitute
if this is internal bacteria? Would the Epsom salts work here to loosen
things up? Please advise.
Thank you.
Ben
<Please (re)read here:

Maroon Clown is Vertical 8/6/05
Hello from the AZ desert- I have a relatively new (3 months) 300 gal
tank.
After cycling, damsels & a yellow tang, we just received an 8"
queen angel, a 5 " powder blue tang and a 3" maroon clownfish. After 24
hrs, they seem to be adjusting well, except the clown. Though they all
ate well, last night, it chose a far wall of the tank and has been in a
vertical swim position it seems all night and this a.m. Is this normal
stress?
<Likely so... could be a puncture/wound from
decompression...>
What else might I watch for in the event a problem
is percolating?
<Not much else to do, or that I would do... Bob
Fenner>
Clownfish with White Bump 8/5/05
Hi,
<Hello there>
I have noticed that my Ocellaris Clownfish has a white
bump on the bottom side of his head. There is only one bump. I don't
know what this could be as I have never seen it before. I have also
noticed that a small part of the dorsal fin looks a little ragged & that
part of the fin has white tint to it. My other clown in the tank is
doing fine with no problems. Also My tank has been set up for 5 months.
I have heard that a single white bump might be a viral infection
<Maybe>
but I don't know this for sure. Please let me know if this
is cause for concern. This is my first saltwater tank ,but I have kept
freshwater for about 5 yr.
Thanks,
Scott
<Could be resultant
from a physical injury... a bump... might be an internal complaint
manifesting itself. Please read here:

Dead
Percula Clown 8/4/05
Hello Crew,
<Dr. E.>
I am in
mourning, last night one of my percula clowns, I have had for 4-5
months, died unexpectedly. I noticed the night before he/she was
swimming in place and breathing very fast and was not interested in
food, which was a first. The next day I came home from work and it was
getting its final cleaning from my skunk cleaner shrimp. My other fish
(yellow tang, hippo tang, 2 firefish, royal Gramma, flame angel, and
perc clown) are doing very well in my 120g reef tank. I checked my
parameters (ammonia, pH, SG, Salinity, Alkalinity, Nitrate, Nitrite)
they are all normal (or haven't deviated over the last 6 months). I
haven't added any new fish in over 2 months. I have live rock and
assorted corals and clams. Do you have any clues of what might have
happened?
<Mmm, not really... mysterious... but does happen with
these fishes>
I inspected the body of the dead clown and there was
no evidence of external parasites or trauma. I get a lot concerned when
a fish dies, especially a hardy clown.
Thank you.
<Me too... I
do suspect some aspect, internal complaint... not easily detected by
gross necropsy... Perhaps a genetic disorder. From your writing, I take
it you have at least another clownfish... and that it seems fine... I
would replace this lost one with another of the same species, tank bred.
Size, smaller. Bob Fenner>
Clown colour and filtration 7/30/05
Hi there WWM crew!
<Hello Matt>
Firstly, stellar job on your
website. Stocked to the rim with golden advice, and always a pleasure to
read.
I have two questions, totally unrelated to one another. I have
searched the web for answers to these, one of which I have found heavily
contradicting info, the other zip. So, I thought I'd milk the teats of
your mind and hope you gurus can shed some light :)
<Slurp>
Here
are my specs to give you some background:
24 gallon (approx
18"x18"x18") tank just over one month old. 30 lbs of live rock. Two 36
watt high compact fluorescent lights (50/50 actinic). Saline Solutions
40 hang-on skimmer (counter-current airstone type). pH = 8.2, Ca = 450,
Nitrite = 0, Nitrate = 0.2, Ammonia = 0, Gravity = 1.025, Temp = 83,
Phosphate = 0.1, Alkalinity = 'High' (Red Sea test kit unfortunately
doesn't give me a numerical reading).
<Mmm, you might want to read
over re synthetic salt mix brands...>
I conduct weekly water changes
of 10%. And twice a week I add Seachem Reef Calcium.
<I would wait
on the changes, supplements... for another month or so>
On one
occasion I added rotifers and phytoplankton.
My livestock is: 1
Turbo snail, 4 Astrea snails, 2 Nassarius snails, 3 blue-legged hermits,
1 red legged-hermit, a brown brittle star, a Lysmata amboinensis cleaner
shrimp, and a percula clown. I also just recently added a small frag of
green daisy/clove polyps, to test my conditions. They seem to be doing
well as they have grown about 5 new stalks in one week. My live rock
when purchased was brown, and now it is nicely coated in purple and
green coralline, and loads of life in every cranny. My plans are to add
1-2 more small fish, and some soft and LPS corals.
<All in a 24
gallon system...>
My first question relates to my filtration. My
tank is a Nanocube DX. Its design includes an existing filter in the
back housing that contains a large 16" sponge pad, ceramic rings, bio
balls, and active carbon. The intake is an overflow that is governed by
a power jet on the other end that provides a flow rate of 290 GPH. I
recently added my skimmer (removes some nice gunk on an every other day
basis) and was advised by a friend to remove the sponge pad, ceramic
rings and bio balls.
<I would also wait another month for this
change... and not add any more livestock for at least this period of
time>
Leave the carbon in and place live rock in the chambers. To
which I did. (slowly adding live rock, so not done this part yet). All
is well so far, but I have read info on websites, including here, that
advises people of similar tank sizes that they should add a hang-on
filter when just using a skimmer.
<Yes>
I'm wondering if you
feel my current setup is fine, or if I should revert back to the
mechanical/chemical filtration the tank came with, while also keeping my
skimmer going?
<I would>
Second question concerns my clown. When
purchased he was a rich orange through and through. But as the weeks
have unfolded, he has begun to darken. Starting at the top spinal area
and it is evenly working its way down his body.
<Stress... from the
conditions, transitions of a new system>
A dark brown colour. Smooth
in transition, not splotchy. He seems in good spirits, curious and
explorative. I'm wondering if this is a concern that needs to be dealt
with, or if it is natural, and if so will it return to orange one day?
Thanks so much for your time. And cheers to the whole crew at WWM!
Matt
<Thank you for writing so clearly, completely. Your clown will
revert to brilliant orange with good care, nutrition and time. Bob
Fenner>
Spotted clown 7/27/05
I purchased two tank bred
ocellaris clowns a few weeks ago and they never got along well.
<In
how large, set-up, established system?>
For awhile I let them be
hoping they would "work it out" as they are both juveniles. The one who
was constantly being picked on slowly started to develop black spots
which I attributed to stress/melanism as the aggressor never developed
any spots.
<A good guess>
This same clown would also have a
ragged fin once in awhile, presumably from being picked on. Last week
the more aggressive fish would not stop biting and chasing him and he
developed many (approx 10) black spots and was hiding in the corner with
very ragged fins. I separated them (the aggressor moved into my
neighbor's tank) and both are doing really well now as they each have
their own tank. The poor little guy's fins have healed up and he is
more active and eats well, but he has kept all of his black spots (no
new ones, though). He really looks funny!
<Am not laughing>
Water quality has remained normal (amm, nitrate, nitrate =0, SG=
1.024, ph= 8.2). Will these spots resolve or is he destined to be a
spotted clownfish?
<Will likely "go away" with time (a few months),
growth, good care>
He is now the only fish in the aquarium (12
gallon nano). Thank you in advance for your knowledgeable advice. Your
site is what has guided me through this venture!

Clown getting better 7/29/05
Hello WWM Crew,
<<Hello, Ted here>>
I got the water tested and
performed a water change. My clown got better. It has started eating a
little. I wanted to know whether to use dechlorinated tap water or
mineral water? My dealer recommended I use mineral water. I would be
thankful for your help.
<<In the long run, you are better off
investing now in a RO/DI filter. It is more money up front, but you can
then filter and produce high quality water whenever you need it (which
should be frequently since you should be regularly changing water). If
you are going to buy water, buy RO/DI water (not mineral water). Use
dechlorinated tap water as the last choice. Good luck, Ted>>
Clownfish Woes 7/27/05
Good day Mr. Fenner.
<Mike G here,
Bob's a tad busy lately.>
I have a 10 gallon tank with coral sand+a
powerhead+a rubber airstone.
<Airstone is unnecessary, in my
opinion. Perhaps a skimmer is in order, however?>
I put a orange
finned clown in the tank.
<Cycled?>
it is my first fish.
<And a good choice at that.>
It has been there for over a week now.
It does not eat anything.
<Not a good sign.>
I tried almost
every thing.
<Which entails...?>
Yesterday it got covered with
white spots.
<Related to an unidentified stressor. Take your water
to your pet store to be tested, ask them for the actual numbers. Make
sure your tank has cycled.>
I increased to 30c.The white spots have
disappeared but the clown does not eat any
thing.
<They'll be
back, most likely. Since you don't have any inverts, why not dose a
copper-based ich medication, coupled with a decent water change? Good
luck, MikeG>
Re: Clownfish Woes 7/28/05
hello WWM crew
<Mike G again>
I will get it done as soon as possible.
<Good to
hear.>
thanks for your timely help.
<Welcome.>
can I add a
anemone and another clown.
<Yes, you can add another clown (once
this problem is solved), but you'd need proper lighting for an anemone.

Help with clownfish 7/26/05
Recently, I did a
renovation of my 55 gal. tank. It had been running for several years,
using UV Sterilizer, protein skimmer, standard wet/dry filter, JBJ
compact Fluorescent lighting, and about 70 lbs of LR. I performed a 75%
water change, scrapped the algae off the glass, let that settle and
vacuumed most all of the debris out, and scrubbed most of the filtration
equipment with tap water and a rag. After the revamp, I had a black and
gold Chromis (the only fish that had been living in the tank, apprx. 2
inches long), and added 4 false percula to the tank (2 from a chain pet
store roughly an inch in length, the other 2 were from a privately owned
pet shop, about 1.5 inches in length). After a modest amount of
aggression from the Chromis, things seemed to be going well. Then
trouble hit, both of the smaller clowns died within a day of each
other... now several days later, one of the larger percula's is laying
on the bottom of the tank - with the occasional burst of energy, is not
looking well. All levels are great, salinity 1.019,<Salinity is a
little low, Joe. What was the salinity of the water where the fish were
purchased.> pH 7.9, ammonia and nitrite are non-existent, nitrate is
about 40ppm, and water temp is 79 degrees F. The one thing I did
notice, once each of the 3 percula's started to swim a little funny (the
latest was swimming almost vertical for a few hours today), they stopped
eating. I also noticed that the remaining, healthy percula doesn't seem
to be eating either. I've been feeding them mostly flake food (which
they did eat when first introduced to the tank), some frozen brine, and
just picked up Spectrum pellets and some frozen Mysis shrimp, which have
also remained untouched. Taking the LFS owner's advice, I've separated
the Chromis (using a freshwater breeder net I added to the tank). Not
sure what the cause for this is, but I'm at wit's end; short of
disposing of the sand and LR, completely draining and restarting the
tank, I have no idea what to do. Thanks in advance for any help/advice
you can provide. <Would like to know how the fish were acclimated and
what the dealer's tanks salinity is. Sounds like a shock problem to
me. James (Salty Dog)>
Al
Sick Amphiprion ocellaris...
actually mis-purchased, crammed into inappropriate setting 7/24/05
Hey folks:
I have a wild caught Amphiprion ocellaris, he/she is
rather mature and about 3 1/2 to 4 inches in length.
<Wow, a big
specimen>
I am in the process of setting up a 70 gallon diamond tank
and when I saw this unique looking clown (the white stripes do not fully
circle this fish, they start at eye level and cover the top of the fish
ending at eye level on the other side, kinda looking like a hat!) I knew
he'd be perfect for the tank, but unfortunately the tank won't be able
to support livestock for quite some time. So for now he's staying with
some friends in my 28 gallon bowfront tank. This tank is really
peaceful, I have 2 smaller juv. ocellaris's (approx. 1" in length) a
cleaner wrasse, a scooter blenny, a young coral beauty, bicolor blenny,
a small yellow tang, and a small scopas tang.
<Real trouble here in
terms of crowding, aggression...>
There are plenty of hiding
places/caves, two anemones (Condy and bubble tip), frog spawn & flower
pot corals.
<Even more, worse troubles...>
The problem I'm
having is that the new clown has a greyish look to him, he's not a
bright as the other two that I have (they all do get along), The clear
tips on the ends of his fins are starting to disappear, almost
completely gone on his tail fin. What can be doing this?
<... mainly
the fact that the animal is poorly adaptive, adapting to captive
conditions, is housed with toxic cnidarians...>
I was hopeful that
he'd be fine for a few weeks until I can transport him to the other
tank. I've tested the water and the only thing that outta whack is the
nitrites (normally zero) they've jumped up to about 30.
<Mmm, you've
got this turned-around>
The nitrates & ammonia are both perfect. The
ph is at 8.2 or 8.3. Any advice or suggestions?
Thanks,
Ross
<... large wild-collected marines of all species poorly ship, adjust...
mixing anemone species, keeping Goniopora... in small systems is a
recipe for disaster... I would "spread" these animals out, return/trade
some in... quick. Please read on WWM re these species care... Bob

Clownfish <actually, crowding, mis-stocking...
iatrogenic disease> 7/20/05
I just purchased a clownfish from my
LFS. I also have one blue yellow-tailed damsel and a large hermit in a
20g marine tank.
<... the last not to be trusted>
At first the
clown was fine, but recently he has stopped eating and seems to swim
vertically (his head pointed to the surface). It seems that he has some
trouble swimming as likes to hang out by the filter in the back of my
aquarium. I've been looking all over and I can't seem to find out what
is wrong with him. I would really appreciate your feedback. If you
could email me at XXXX
I would be most grateful.

Ocellaris with fuzzy fin 7/18/05
hey there. Every couple of days
something fuzzy, cotton ball like, shows up on a fin. It will drop off
within 24hrs, but takes a bit of fin with it. It looks like bites but i
am sure it is not. She now has about 20% of her tailfin missing and a
bit of dorsal and a bit of pectoral missing. Otherwise she is in
excellent health. Tank conditions are 80-81 degrees, 1.025 sal, Am - 0,
trite - 0, trate - 10, calc 400, ph 8.0-8.3. She lives with yellow tang,
coral beauty, lawnmower blenny, corals, inverts, etc. She doesn't have
an anemone, but she hangs out around the torch coral a lot. Any ideas? I
haven't found anything like it in the posts. The loss of fin is
outpacing the regrowth and i am concerned. should i dip? If so in what,
and how is a dip prepared (can't find recipes anywhere), thanks.
<Bizarre... maybe this specimen is particularly prone to some sort of
microbial trouble... I would hold off dipping it unless you have another
system to move it to afterwards... the real root of the problem is
likely the system itself... Something there. I would try the usual
bolstering of the fish's health with vitamin soaking its foods...
Perhaps see if slightly lowering the spg (a few thousandths) will favor
the fish, not harm your invertebrate livestock. Bob Fenner>
Sick Percula 6/29/05
Hello ~
I have a percula fish who has
recently displayed dark spotting on his face & front fins; his mouth is
lined in black too. Other than the discoloration, he appears fine. I
was hoping that you could please recommend a purifier or any other
necessary measures I could take with the water and/or the fish to help
him get well.
Thank you so much for your help...

- My Clown Isn't Acting
Very Funny! -
Bob,
<JasonC here today.>
I have a two
plus year old tank and fish. We have check the salt level and pH and
everything seems to be fine. We do however have a nasty green thick
algae we have been fighting for 9 month's or so. Up until recently our
two Clown fish have not acted any differently with the algae. Until 3
days ago, the female was at the top of the tank floating on her side,
then the past two days she has been face down at the bottom, rear corner
of the tank. She doesn't even come up for feeding. Our poor male just
stares at her all day. I see that Clown fish have many different
diseases to choose from, how do I narrow the long list to see what is
bothering her. <Hopefully there is some external sign - spots for
instance.> Help, we do not want to loose her.
<Would suggest you
start with a large water change. I'd start with a large change [50%]
right now, and have another one prepared for a day or two from now.>
2nd question, what should I do about the algae, the pet store keeps
telling me the water is fine and I just need to change it more often.
<Please read here:
http://www.wetwebmedia.com/algaeconMar.htm and here
http://www.wetwebmedia.com/avoidingalgaeproblesm.htm >
I cycle
out 20% per week and that isn't getting me any better results.
<5% a
week is plenty. Could be you're stressing the fish by changing so much
water at such short intervals. Would make sure you go through the water
you're adding to the tank to make sure it matches the tank water - pH,
salinity, temperature, etc.>
Sincerely,
Debra
<Cheers, J --

Re: My clown isn't acting very funny!
Me again,
In
speaking with our local water friend store they thought she possible has
bladder infection.
<What?>
Now our second Clown is floating.
Both now are floating on their sides, no signs of body fungus, fin &
tail rot, Popeye or gill disease.
<Water quality... what are you
feeding them?>
The recommend we give them Maracyn.
<For what?
This is an antibiotic...>
We started that on Saturday and they both
look worse. I think based on reading your website we have Clown fish
disease.
<...>
Am I killing them with Maracyn? I've spent hours
on line reading about fresh water dips for Clown Fish disease. Should I
do a fresh water dip.....HELP I love my fish and I think I'm killing
them.
Sincerely,
Debra T. Grobaski
<Check your water
quality, relate this and what you've been feeding these fish to me. Bob
Fenner>
Re: My clown isn't acting very funny!
Bob,
<Debra>
Let me first say, Thank you....
<Welcome>
Feeding:
Omega flake food for Salt water tropical fish (Pinch once a day for
past 2-1/2 years)
<Do try frozen/defrosted or live brine shrimp for
a few days... and maybe a teaspoon of Epsom salt per ten gallons of
water... and see if this relieves the floating, bloat>
Specific
Gravity right between 1.021 and 1.022
PH. @ 8.2
Temp. 77F
What else should I check for you? We do have the skin
like green algae still (past 1 year)
<Mmm, there are a few ways out
of the algal blues... these are posted over and over on WWM. Bob Fenner>
Sincerely,
Debra T. Grobaski
Re: My clown isn't acting
very funny!
I'm taking off early from work to give this a try. I
love my little guy's and will do everything it takes. If you think of
anything else I should try Do not hesitate calling me on my cell as I
will be out getting the brine shrimp and Epson salt for my little
clown's...
Sincerely,
Debra T. Grobaski

A Real Life Nemo?
-- A Percula Query Fest
I've yet to come up with an e-mail title
that you all choose to actually implement on your site.
<Me? Am most
times too lazy to change...>
I'm crossing my fingers this time, but
by all means, change it if you so desire.
<Heee, a bard of fishes,
oh boy!>
Be it known, I've more than copious reverence for you all.
<Hope this is a good thing>
Here's the dealy-o. I have a True
Percula with one pelvic fin significantly smaller than the other one.
<Happens... and not just in Steven Jobs stinky feet features>
It's
almost half the size. Despite this, she gets around without
complication. The fish was purchased in this condition and has been in
my tank for 3 weeks with no sign of regeneration or deterioration on the
fin. It's approximately 2" (The fish, not the fin. :P)... Could this
be a real life "Nemo", if you will?
<... are we... serious?>
Also, on the male Percula, I noticed a spot of darker colored scales
dead center on his body. This spot healed within 2 days but now I
notice another one further back and a little higher. I suspect it will
heal like the previous one did but I am unsure of what this is and what
could be causing it. The only other fish in the tank are a Yellow Goby
and a Rainford Goby, along with the Perc's mate. Possible culprits in
the next few paragraphs...
<Actually, very likely this is akin to
"zits"... stress markings... will go of its own accord>
I did have a
slight nitrite spike recently with the addition of a 10 pound live
rock. The spike never rose above .2ppm and is now back at 0. The
duration of the spike was approximately 3 days. While this corresponds
with the dark spot temporally, I don't believe the nitrite is the direct
cause.
The only other thing of note is that my pH is a mere
7.9. I've been using a buffer as directed for the past 2 days and
anticipate getting it to 8.3 over the next week. Perhaps this is the
cause?
<This, the nitrite, being new...>
I have a
Fire Shrimp in the tank as well but the aforementioned fish has yet to
"request" a cleaning.
<Might not>
So the question remains: What
the hell are these darkened spots appearing on my precious fish?
<A
temporary blemish, a tattoo of duress...>
Thanks as always for the
insightful input. I don't know how you all manage to field the influx
of e-mails you must receive but you do a fantastic job of providing
intellectual, honest replies. Do you accept donations?
<Oh yes...
we have an Amazon "begging bowl" on our home page, indices at the
bottom... Thank you for writing... so well, thoroughly, whimsically... a
delight. And not to worry re your Clown. All will be fine in time. Bob
Fenner>
Brown spots on my
clown fish Hi, <Hello> I have a 55 gallon reef tank
which I started about 4 months ago. I currently have two clownfish
in there and about a month or so a go I started noticing brown spots
on one of them (on orange colored stripes only) then both of them
became covered in these brown spots within a week. The fish are
eating aggressively as usual and are very energetic, everything
seems normal aside from these spots. The spots are not raised out
of the skin and the fish's scales seem in good shape. <I see
this> I have attached a picture so you can have a look and maybe
figure it out? We feed them brine shrimp about once a week and Red
Sea Marine Gro pellets everyday. I have searched for advice on the
web and other sources and no one seems to be able to explain this.
Some suggested that it might simply be a pigmentation anomaly?
<Yes... this is what it appears to me> Anyway thanks in advance
for the help and you have a great web site. I have been able to
found lots of useful info on there to help me out with my new tank!
Nathalie.B <I would not be concerned here. In all likelihood
this coloration will change with time, growth, and your expanding
your fish's food selection to include more vitamins and protein. Bob

Snail Search...
Hi Crew,
<Scott F. here today!>
Thanks
for the reply to my last questions. I had an unsolved death a couple of
days after I sent the last E- mail. On Sun. I noticed one of my clowns
had a little nick in her tailfin. I had also noticed her swimming around
the top of the tank in the current with clamped fins. She was
eating well and she would come down and swim with her friend so I let it
go. I also noticed her jerking forward a few times, other than the nick
in the tailfin she had no visible symptoms of anything. I awoke a couple
of times that night and checked on her. She was on the bottom, she was
upright but would sometimes stop moving. I had seen both Clowns on the
bottom after lights off ,so I did not find that too strange. What was
strange was her tailfin was even more ragged. Still I waited, I was
hoping she would swim up in the morning and I would get a qt ready. In
the morning, however, she seemed more listless and breathing heavy. I
moved her and ran out for some antibiotics. [I could only guess
a bacterial infection] I had read Clowns are sensitive to Furan
compounds so I got Kanacyn. She died later that afternoon. I had her for
almost five weeks and she had seemed fine. Its been a couple of days and
so far the other fish seem fine. Any ideas?
<Hmm...In the absence of
visible symptoms, it's so hard to guess. The difficulty in breathing
seems to be indicative of either a parasitic disease or an environmental
lapse of some sort. I'm afraid that I could do little more than guess at
this point.>
They were supposed to be tank bred but now I'm kind of
wondering about that. I stocked up on Spectrogram, Kanacyn and already
had Furan-2. [the guy at the LFS said Aquatronics is going out of
business?] I had added about 24 Nassarius Snails on Sat. but I believe
the tailfin was already nicked. I was hoping to add another Clown if the
other fish remain healthy. [ after 4 weeks in qt. of course]
<Yes...quarantine is the way to go! Do buy form a source that can assure
you that they are captive-bred.>
Another quick question, if you
don't mind. I made an E-BAY impulse buy! I had been on a role, I had
already bought a [very] used 40 gallon for $25.00, a new large hang on
refugium with light and pump for $ 130.00 [ I really want to build a
sump with one of my 30 gal. but I am scared, with my luck I would flood
the living room] So my impulse buy was 100 Ilyanassa snails. I had read
great reviews on E-Bay from other buyers and bought them, THEN checked
your website. I did not find much. I have since read mixed reviews on
another site. The bad I read was that they are predators, they carry
Flukes, they don't live long in warmer waters. Then I would read the
exact opposite! I put them my 20 gallon for now. Any info you guys have
on these snails would be very much appreciated. Thanks so much,
Kim
<Well, Kim- my best recommendation would be to do a search on one of the
larger search engines. To get the most accurate information on these
animals, it may be better to turn to academic sources like university
biology departments, etc. Sorry I could not be more specific, but this
is a species that I have no personal experience with. Perhaps one of our
other readers could share his/her experiences on this one. Good luck!
Regards, Scott F.>
False percula this time 05/07/2005
Thanks for helping with my skinny yellow tang. fed her once with
Metronidazole and she is fattening up after only 24hrs!
Well the
clown is in quarantine with another false percula. They have both been
in the hospital tank for 14 days. Two weeks ago they were about the same
size and temperament. One has eaten well and is growing fast, the
other's eating has declined and has appeared to become very shy. They
both exhibited signs of pairing. The smaller male will shiver on his
side in the presence of the "female". They are still quite small, one
just over an inch and the other smaller than an inch. Well the smaller
clowns behavior has started to concern me. (The larger clown is very
active and not at all shy, she responds rapidly to feeding - Mysis with
garlic and vitamins) He spends most of his time hiding under the coffee
cup, or pressed up against the side of the tank and resting on the
bottom, or up in the corner pressed against the power head. He does eat
some and can get perky every now and then. I just noticed tonight that
his mouth looks a little puffy, white film or mucus, and one eye is a
little cloudy, seems to be enlarged too. I can't pin it down to any one
thing. Velvet, Brook, Nutrition, water quality?
Two days ago,
Chemistry was NH - 0, NO2 - 0, NO3 - 10ppm, PH 8.1. Right now it is NO2
- 0.25, and NO3 - 80. PH is at 8.0. I have been changing water (20%)
once a week. and monitoring chemistry every few days. I don't know what
caused the change. I have been slowly lowering the salinity, it is
presently at 1.020. I will make a 25% change right now and see if this
helps at all. I am changing with water with cycled water with good
chem. Do you think i should begin any medication treatments.
<Is the
female beating him up? Sounds like a recent problem I helped someone
with where the female would just kick the crap out of the male.. Make
sure to watch for that...>
Thanks again. Robert <Yep EricS>
Now
I REALLY Need Help! - 06/17/05
Thanks for the help, but my
situation has gone from bad to extreme!
<<Uh oh!>>
The one clown
that was struggling has died, and I couldn't find the body for a couple
of days. Later, I did find part of its corpse stuck to the sponge
element on the hang-on overflow. But, during this time the ammonia level
went from 0.25 to 8.0+ (the color test card doesn't go higher)!
<<Mmm...am suspicious of your test kit, that little clown shouldn't have
caused this kind of spike.>>
I did a partial water change, added two
bottles of Ammo Lock, and 17oz of AquaScience Ultimate (the LFS said
this worked the best for ammonia).
<<Not saying some of these
products don't have a purpose...but depend more on large water changes
(dilution) and good husbandry practices to reduce pollutants rather than
on "magic in a bottle.">>
All of this only reduced the ammonia level
to 4.0.
<<Try another and/or different brand test kit.>>
I don't
have a quarantine tank (I know I should though).
<<Yes>>
So, I
have the remaining clown floating in a plastic bag with freshly made
saltwater, and an air pump blowing air into it. I'm trying everything
that I can think of to save its life. I'll change the water everyday in
the bag, until the tank becomes safe again.
<<Do this fish a favor
and give it to someone or take it back to the store.>>
The owner at
the LFS said he's never heard of ammonia levels that high.
<<Me
either.>>
Again, he said to add $500 worth of live rock, but I don't
have that kind of money right now.
<<You don't need to add ANYTHING
to this tank until you determine what is going on and correct this
problem.>>
Then he suggested turning my sump into a wet/dry system,
and that this would also solve the problem. Do wet/dry systems work that
well?
<<For FO/FOWLR systems a wet-dry can be quite useful...not
recommended for reef systems.>>
Also, how could the ammonia level go
so high, so quickly?
<<That's the $64,000 question. Do try a
different test kit to confirm.>>
Sorry for the extra questions, but
I'm feeling quite disillusioned
marine tanks at the moment, and
desperately need some guidance to keep my favorite hobby going.
<<If
new tests determine your previous measurements were correct, Then maybe
changing out the rock is the best thing. But I find it hard to believe
that after three months the rock would suddenly cause this kind of
problem. Get another test kit (I like Seachem) and see what it tells
you. The we can go from there.>>
Like I said before, you guys are
the only people a trust with my fish. Thanks again! Derek.
<<Will
try to live up to that trust <G>. Regards, Eric R.>>

Clownfish Problem -
I just purchased two percula clown fish
today. They were swimming fine at the pet shop, however when I put them
in my tank, the smaller clown began gulping for air and stays at the top
of the tank, in a vertical position with its mouth at the
waterline. I'm not sure what is wrong, can you help? <Time will tell...
perhaps something you did in the way you acclimated this fish or even
something in your water that is causing this fish distress. If you don't
have the test kits, would suggest you take a sample of water to your
local fish store and make sure everything is on the level. You may need
to execute a water change if things are off kilter. Cheers, J -- >
