|HLE Suggestions 5/15/10
I have a 90 gallon SW tank, 100 #'s live rock, 4" DSB. Up
since Jan (was established before then with prior owner) You guys
have helped me through Quinine Sulfate treatment on my Blue Tang,
THANKS! Now the same tang appears to have HLE.
<Appears to be the beginnings of>
When I first got the fish it would not touch Nori, he ate any
frozen food, and flakes, no pellets. I've fed a variety of
Mysis, frozen form 2, Spirulina brine, marine cuisine, and 1 and 2
flakes. I finally got him eating purple sea veggies brand Nori
about 2 weeks ago (the same time the first spots of HLE had shown
up) Last week I got Selcon and vita Chem, and am soaking food in
one of those each day (rotating).
I also purchased Emerald Cuisine Frozen (he likes) and Spectrum
pellets (which it doesn't seem to eat).
<Give this time>
I added a grounding probe,
<Mmm, usually not of use>
I do weekly PWC's of about 6 gallons. I run a smallish skimmer
and a UV, along with a Tidepool sump. I use Seachem's phos
guard, as well as Purigen. My water tests Ammonia 0, Nitrite 0, and
Nitrates are now 0 (used to run around 10-20). I'm wondering
what I'm missing to help the fish,
<Likely just time going by... though DSB, "mud" use
can be useful adjuncts>
I tried to attach a picture but he dives in the rock when I get the
camera out. Do I need to treat for a bacterial infection?
Any suggestions are welcome. I do have a QT cycled and running with
a gramma and 2 Sharknose gobies, they've been in QT for 3 weeks
doing well. I "could"
move them to the DT if I need to treat the tang in the QT.
Thanks, Pam Speck

Blue Tang Sick Or Injured??? Please help!
<8 megs of pix?...>
I have a Blue Hippo Tang and I can't really tell if he is
sick or if he has somehow injured himself and I'm not sure
what to do for him. I've had him for about 6 months and have
never had any problems with him being ill before. He's eating
well and he doesn't seem to be scratching himself against the
rocks or anything but he seems to have developed some sort of
red, pimple-looking thing near one of his gills that looks like
it extends to under his skin if that makes any sense. The best
way I can describe the way it looks is if someone had taken stick
pin and stuck it right under his skin leaving the round end stuck
out. So, I don't know if I need to try to treat him for some
sort of disease or try to figure out a way to remove this thing
from him. He is swimming around as usual but does seem to be
favoring the fin on the side where this spot is. I've
attached pictures to try to give you an idea of what it looks
like Any help you can give me will be greatly appreciated!

patient here. Bob Fenner>
I have a hippo tang with it's freckles turned white...
I don't know if it is HLLE or not...

Poor Tang. Hippo hlth. 3/4/10
My Hippo Tang seems to be having some sort of parasite problem. On his
side is what basically looks like a white head pimple (appeared within
24 hours), almost like something attached itself to him or came out of
<Just one such spot? Don't worry>
He is on the rebound (Hooray!) from an HLLE issue, which the folks at
WWM graciously helped me (and him) out with solving, Thank You.
At first I freaked out when I saw the "zit" and started to
lower the salinity, but then decided against putting him under any
excess stress that may send him into an HLLE downward spiral.
I am fairly sure it isn't ich, as it doesn't look like a grain
of sand and as far as I can tell there is only one maybe two (could be
"zits". Appetite and behavior are not affected.
I can't find any good images of flukes to compare, so I turn to
<Not a trematode...>
I should mention one important yet embarrassing piece of
While I wasn't home, a family member introduced a new fish to the
They proudly told me how they acclimated it and made sure it could live
with its fellow tank mates (it was a fish I was looking into
Sadly, no quarantine, my heart sank.
The new fish doesn't have any symptoms or sign of disease, so maybe
the timing is coincidental.
I have a ten gallon quarantine tank that will not house all of the fish
(Hippo Tang, 2 Clowns, 2 Firefish, and a new scooter blenny). If they
need medication (only the Hippo Tang has "zits", should I
just medicate the main tank, while moving my live rock, shrimp, and
snails to the quarantine?

Re: Poor Tang -- 3/6/10
Thank you for such a speedy reply.
The disease has progressed on my Hippo Tang and it almost definitely
looks like Ich now (White dots in various locations on his body).
I purchased Mardel CopperSafe,

<Keep reading... and soon. B>
Re: Poor Tang 3/10/10
My Blue Hippo Tang still has ich, though with
improvements in breathing and activity.
I returned the copper medication, good thing I had second thoughts on
I did purchase Kordon Ich Attack, and have been treating the display
tank for four days (along with a temperature increase).
<What do you think of this (alternative medicine) product?>
I feel foolish for thinking that such a amazing product could exist. It
is true to its word in not effecting inverts and allowing for steady
water parameters. The lack of spike in ammonia probably indicates that
the product isn't even killing other pests (worms) in my tank.
I am going to finish out the directed dosage though, as while no cure
something I am doing is helping my Tang.
I have also pumped the fish's diet full of vitamins in hopes of
boosting immunities. I have read garlic can help, but I must disagree,
I think it only acts as an attractant.
I am in the hunt for an affordable 55 gallon QT tank, hopefully it will
suffice for my Tang, 2 clowns, 2 Firefish, and scooter blenny.
If I still don't have a QT big enough and the Tang still has a bad
infection of ich after organic treatment, I am going to have to
medicate the display tank with non organic medication. I know it is a
really bad thing to do and you already said definitely not, but I
can't just watch my fish die, he is truly part of the family.
<... this runs contrary to your statements re not dedicating
resources for it/their care>
I have read that if treatment to a display tank is a must, the drug of
choice is Quinine (I believe you also recommend using it, only in
<Chloroquine Phosphate is my/the current "genie in a
bottle" here... But should be administered in "bare"

Incredibly deteriorated tang still living
I accompanied a local aquarium maintenance guy this afternoon for
the one and only reason to get my opinion on a sick fish.
This fish literally looks like a swimming "two face"
character. Its a common hippo tang about 8" in length, swims
, eats, and acts as if no stress or pain is incurred.
Massive tissue degeneration, almost completely devoid of any
<Not that uncommon unfortunately... likely what hobbyists
label a very advanced case of HLLE...>
No other fish are affected in the aquarium included in which are
two other like sized hippo's.
When swimming in front of a powerhead on occasion you can see
chunks of the flesh fly off. Appears to be extremely rapid.
The fish owner is emailing me pics as soon as she can get
All she wants to know is name or the disease for reference. She
is willing to try and help the fish all she can without causing
harm to the others. It may very well be a lost cause on this
particular fish sorry to say.

Sick Hippo Tang question 1/27/10
I have a Hippo Tang that seems to be suffering from HLLE. His symptoms
are holes above and below his eyes and along his lateral line (they are
getting bigger). <Ok>
He still has an absolutely wild appetite and only hides when spooked by
out of tank sources, he spends most of the time "schooling"
with the two clowns he shares the tank with.
<Nice behaviour to watch!>
I have taken some steps to cure him, but nothing seems to be
The Nitrate levels are higher than desirable <a factor>, so I
have started doing smaller and more frequent water changes, I also
purchased a protein skimmer.
<Mmmm, you should have had one of these from the start>
I got him to finally eat seaweed by tearing it up and soaking it in
Mysis shrimp before feeding (he doesn't take seaweed from a clip).
His diet consists of Mysis shrimp, seaweed, and flake food.
<Ok. There is no proof as to what actually causes this condition,
but improving the diet and environment can bring about a halting and/
or a reversal. I would start with the diet here: Cut out the flake and
replace with a decent pellet food such as New Life Spectrum. Feed this
as the staple with a little Mysis every few days. I would soak the
seaweed (Nori?) in a vitamin supplement (something like Selcon) before
feeding daily as well. Don't overfeed so that it affects your water
It has been several months with what I believe is HLLE and I don't
know what else to do. I heard that activated carbon can be a problem
(which is what I use), what can I use instead if it actually is the
<Mmmm, I am not convinced by this 'carbon as the cause'
argument. I use carbon continuously and my fish have never suffered
from this condition. I have also bought 'second hand' fishes
with this condition and halted/ reversed it. The only way I see carbon
as being a cause would be if it 'removed' some 'mysterious
but necessary' element. If you do your water changes regularly then
you should be replenishing anything lost. As stated, there is no proof
for any cause, but IMO a clue is that a) Wild fish don't get this
at all, and b) Improving the environment & diet works. Fishes like
Tangs & Angels need space, give them this and a decent diet and you
should see things right>.
My Hippo Tang shares his tank with two clowns, two Firefish, and a
coral banded shrimp, all of which are healthy.
<In what size tank?>
The water parameters are (non reef):
<Non-reef systems commonly show this problem on fishes
(environment). Do you have live rock w/ algae growth? If not, I would
suggest adding some>
Nitrate - 40 ppm
<Too high and probably a contributing factor>
Nitrite - 0
pH - 8.0 to 8.5
Specific Gravity - 1.021
<Too low -- I would gradually raise this to 1.025 -- 1.026>
Temperature - 76 degrees F
<No problem, I think there are a few things you can do. Try reading

<I like helping fishes so it is no bother!>
The specific gravity has been raised, and the nitrate levels are
finally going down.
The holes along his lateral line are actually healing (no healing on
his head yet though).
<Really? Already? Excellent news, as this usually happens very
slowly over a period of weeks, months>.
You asked me about live rock, the answer to your question is yes I have
some, but not much. I have set up a spot to start curing more live
rock, but have not bought any yet.
<Good, this will add much in the way of 'goodness' to your
tank, both seen and unseen>
There is algae growth on the live rock and elsewhere in the tank.
There is green hair algae (which I have to remove by hand), but there
is also a beautiful purple algae all over the live rock.
<Coralline algae. See here:
Is the purple algae good for the tank because I would love to keep
<Yes, is desirable>
After everything settles down in my tank for a while, I think I would
like to purchase a new fish.
I am leaning towards a Blenny, specifically a Lawnmower or a Scooter. I
was nervous about possible aggression towards my Firefish. Do you have
any advice on which would be a better addition to my tank?
<Lawnmower Blennies (Salarias) can be aggressive. Scooter Blennies
will fit much better here, but you need to ensure you have plenty of
'live' food in the way of plankton in your system to support

Blue hippo tang with ich 1/12/10
I need a recommendation regarding proper treatment of my hippo tang.
Pretty sure he's got ich; white sugar-like spots a few days ago,
then they increased in number, ultimately coalescing. He's behaving
normally, and eating. I've moved him to the quarantine tank and
have put in some copper.
My question is whether you'd also treat with an antibiotic to
prevent bacterial superinfection of the parasite's entrance/exit
wounds, or whether that would be overkill/dangerous. If antibiotic,

Re: blue hippo tang with ich -- 01/12/2010

There's no redness associated; just looks like little holes in the
skin. The fish hides in the decorations mostly, but does come out to
eat when I put a few food pellets in.

Please help!! What's wrong with my PYTB tang!
First off I must say I love your site, it has been very helpful
in most of the questions I have ever had about my tank!
Second, I hope you can help me, there seems to be something wrong
with my new PYTB tangs dorsal fin. I did do a search, but other
then Lymphocystis I have no idea what it could be.
I have a 75Hex tank
<Mmm... Not ideal shape or volume for Paracanthurus>
that has been set up for a little over a yr. I have a canister
filter, skimmer in the sump and power head. About a 2" sand
bed and about 100lbs live rock. I do water changes only about 1-2
times a month 20% at a time Last water change was a week ago
right before I added the two new fish. Temp 78, Nitrites,
nitrates, phos. all 0. I am unsure of the ammonia because I ran
out of that test a couple weeks ago. ( I will go get one
Sg 1.024 PH 8.2 Calc 500 it's always a little high I think
because of the rocks (about 50lbs is that Texas holey rock which
is limestone I think?) I don't supplement it.
Coral= about 7 groups of various Zoas, a Small group of Palys, a
Duncan that has grown from 1 head to 8 in just a few months, a
small hammer and a small torch, Favia. and a red/purple
gorgonian. All have been doing fine.
Fish= a pair of Perc. clowns, a 6line wrasse, lawnmower blenny
and a scooter blenny(I think that's what it is) and a 3 line
damsel that I just can't seem to get rid of! I had him in a
10 gal for 3 yrs prior to setting up the 75 and he is quite the
<Ah yes. Dascyllus species...>
He always bites me when I have my hands in the tank, but at least
he is well mannered with the other fish.
Then the 2 new additions a Foxface lo and a PYTB tang.
There's about 20 or so blue leg hermits, a 4" cleaner
shrimp who has now become lazy and won't clean anyone
actually the anemone shrimp cleans better then he does... 5
peppermint shrimp, olive snail, horseshoe crab, 2 emerald crabs,
a porcelain crab, and a few other small snails.
I also just added a few 2"cleaner clams to the sump.
There is about 7 mango grove plants in the back of the overflow
box since they grow out of the water.
A few months ago I had a huge hair algae breakout, (right after
the UV broke..) mostly due to over feeding I think though.
Nitrates were around 20+ so I worked on getting them down and had
been scrubbing the rocks best I can. Since the Zoas and other
coral are attached I can't really pull them out to scrub
them. Most of it is gone/dead but some still lingers on.
Because there was/is dead hair algae clumps that have gotten
stuck on the sand, red slime started to grow on it. I treated a
few times with ChemiClean. It seems to help.
<Dangerous... are the chemical trade offs worth it here? I
would look to other remedies>
Ok on to the biggest problem. I got a 5" Foxface lo and a
4" PYTB tang to try and help with the remaining algae. QT
for 3wks. The tang and Foxface are buddies and a lot of time the
swim together. The tang is very outgoing the Foxface is a big
baby and hides if people walk past the tank but he does eat the
algae all the time so that's a plus.
When I put them in the main tank (about a week ago) the tang got
a few spots that may be ich but they look like it's under the
skin so I'm not sure what it is and it they haven't
multiplied. She has been swimming to all the shrimp and has
rubbed against the rocks a few times, but the only shrimp that
even climbs on her is the anemone shrimp. ( I had no idea they
<Indeed these Hippolytids are>
The skunk shrimp was also getting ready to molt again so I
suspect that may be why he wasn't so interested in her.
I have had ich in the tank before when I first added the clowns
(no QT since the damsel was the only one in the tank at the time)
but everyone seem to get over it. Every once and a while I'll
see a white spot or two but it never spreads and always goes
away. I am aware that it will always be present as long as their
are fish in there. For the most part the UV(when it was working)
and the skunk shrimp had made sure I don't have an
So after going to bed last night everyone was acting fine and
this morning when I turn on the lights the tang comes out with
this swollen bumpy dorsal
fin. She is not her happy self and is swimming awful slow around
I feed the fish mostly frozen food. (marine 2 and vitamin
encapsulated Mysis) and Nori for the tang but when ever she eats
it she spits it out and then eats it again. Sometimes she
doesn't actually eat it though... I just now feed them a cube
of Mysis to see if she would eat it and she darted for them so
she is eating but otherwise she was swimming pretty pokey.
The only thing that had changed from last night to this afternoon
was I added a few cleaner clams to the sump(all still alive) and
I put in a dose of ChemiClean (last dose was over 2wks ago)
because there was some red slime on the sand again.
<Mmm, do read here re:
and the linked files above till you sense you have a good grasp
of what your options are here>
I turned off the skimmer and I changed the powerhead to add more
air in the tank.
There is definitely something wrong with her dorsal fin. It looks
like there's a weird growth in it.
<Yes... have seen this before. Often associated with
"stings"... Likely this fish has had a brush with your
Zoanthids, perhaps a poke from the Siganid. At any length, this
is "untreatable", and will improve, resolve itself over
time with good care, propitious circumstances>
It's not exactly white though. She did have a little bit of
frayed fins when I first added her to the main tank but those are
just about healed. Her color seems fine and no spreading of the
spots/bumps (look under the skin for the most part)
Everyone else is normal, even the coral is all opened up and
seems happy enough.
Is it possible she got hit by the Foxface?
They do sleep in the same area and he does get spooked a lot.
When he gets spooked he'll go and hide in their sleeping area
and change to spotty black and put his spines up. But he always
gets over it pretty quick. It's only been a week so I figured
he'll eventually get used to us moving about in the living
The only other thing I can think is she has Lymphocystis but it
doesn't exactly look like that either. Please help me if you
can! I really like her a lot!

Re: Please help!! What's
wrong with my PYTB tang! 12/21/2009
I do hope I am not a bother. Three emails in a day seems a
bit obsessive, but I seem to be overwhelmed with questions
all of a sudden.
Just before switching from dusk to moon lights I noticed
that my tang was breathing quite rapidly (at least twice as
fast as normal) and her dorsal fine looks awful now.
<I see this>
It almost seems that toxin/sting is spreading.
<Actually, the reaction series to it>
The discoloration is also spreading to her body. She is
constantly wanting to be cleaned by the anemone shrimp. But
he happens to live in the Duncans which are on the same
rock piece as a patch of Zoas... The Zoas are closed up at
the moment because it is night, but is this causing further
irritation to her wound?
<Possibly... I would be moving this fish if you had
another largish established system>
Also the shrimp seems to want to pick at the stung area and
she darts for a second but always comes right back to him.
Is the shrimp going to do further damage?
Also if I may, a question about the clowns. They were/are
supposed to be Amphiprion percula but they seem to have
quite a bit of black on them which happened around the same
time as I upgraded the metal halide lamp ( I did so using a
screen over time, to acclimate everyone to the more intense

Dipping a hippo! 11/21/09
I ordered a hippo tang from LiveAquaria. It is supposed to be here

Hippo tang vs. the net 11/11/09
Two days ago I moved my Hippo tang to QT to treat him for ich.
The net got caught on his spikes by his tail and I had to cut the net
to get him free.
In the meantime, one side of his tail is very red and I'm afraid of

Should I treat this with an antibiotic and can an antibiotic and copper
be administered at the same time.
<I would not>
There is still a small piece of netting stuck to his tail. Should I try
to get that off now or let him relax before I stress him out again.
<I have seen this sort of trouble with many fishes over the years,
particularly Tangs/Surgeonfishes. I would leave the bit of net on the
fish for now... it will rot off in time. The redness too will cure of

Hippo tang still sick? 11/10/09
<Reuben... on rye a fave>
After taking your advice and putting my yellow tang into a colander for
a few days and putting my hippo back in the tank not a lot changed, he
did start to eat a bit of food if I put it near his mouth, so after 5
days I decided that I didn't want to leave the yellow tang in the
colander so put him back in the tank but put a panel in to separate the
tank in two.
It's now been nearly 3 weeks since I put the hippo back and
although he has been eating a bit of food if it is put near him he
still hasn't started to swim about the most I've seem him do is
swim up a little go White and then quickly 'fall' back down
almost like he may be struggling to swim properly or he has gone blind.
What could be causing this?
<Mmm, damage from collection/shipping, genetic heritage,
Thought he may recover because he started eating but he seems to be in
the same situation as he was when I put him back.

Regal Tang Breathing Problem 8/5/09
I have a small regal tang (3 inches roughly?) that was first in my
quarantine before my display. It was in there approximately 5 weeks,
and I had used PraziPro for 2-3 days... did a water change.... then did
a treatment with Cupramine because it had ich from the transport from
the store to home...
<Fish do not contract ich on the way home, this fish had the
infection before it left the store. Why did you use PraziPro
(Praziquantel), did your diagnosis indicate the need for this
particular med? This medication is generally used for treating flukes,
flatworms and Turbellarians, and treating tapeworms in our four legged
pets. The recommended 5-7 day treatment isn't nearly long enough to
effectively eradicate ich, generally 21-28 days to ensure an entire
kill. Did you monitor the Cupramine level with a test kit? Although a
little safer than copper, the toxic level of Cupramine is 8mg/L with
the minimal effective dose being 2-3 mg/L. Tangs are very sensitive to
copper and therefore should be treated at the 2-3mg/L level. Another
problem I see is combining medications, no other medication should be
used with Praziquantel. I'm sure your water change did not remove
all of it.>
After all of that, I noticed the fish had HLLE ( vitamin lack I
believe... I try).
<And water quality.>
I then proceeded immediately to order Selcon, Boyd's Vita Chem, and
I mix those into it's food now in a small dish with water, as well
as add some drops to the water.
<One is all that's needed.>
My question is - the fish seems to be breathing a lot faster than
Did the Cupramine destroy it's breathing ability? I don't know
what to do in order to judge if it's breathing is too fast - or if
the Cupramine made it always breathe this fast.
<I'm guessing the fish is no longer with you by now. The rapid
breathing is an indication that the gills are infested with the ich
parasite causing the fish difficulty in breathing.
Generally the last symptom before death.>
The rate at which it is breathing is doesn't seem to vary much. I
can't judge how many times it's moving its gills, (but it would
be as if the fish swam very fast across the tank and then stopped).
I should note that I am writing this only a few hours after adding it
to my main display. It was in a 40 gallon tall quarantine tank

Re: Regal Tang Breathing Problem 8/05/09
I'll go ahead and answer your responses if you don't mind.
<Not a bit.>
I didn't mean to say the fish contracted ich purely on the ride
home - I did the treatment because I did see ich but also as a
preventive with tangs.
As for PraziPro... I had read that PraziPro can be used safely as a
preventative measure as well, so that was the reason I had used it for
3 days before doing water changes to start the Cupramine treatment.
There was no intention of eradicating ich with this, but rather to be
sure it wasn't flukes (shook head side to side in QT - could have
been ich causing this as well).
<Would have been better just to start with the Cupramine.>
The Cupramine worked very well and all white spots were gone. The
treatment lasted 15 days at .5ml and then I did many water changes.
<Good to hear.>
I observed the fish for another 1-2 weeks and saw no signs of the ich
so that is why I put the fish into the main tank.
<Now it makes sense. Wish your email would have had this information
from the start.>
I had also read that copper can cause a fish to breathe faster, along
with having HLLE and water quality - so I assumed the main tank
environment along with other fish and a proper diet would help settle
it down. I still have the fish and it was breathing slower last night,
or at least varying it's breathing rate from what it was
<Good, and hoping the tang makes it. Is it eating well?>
Water parameters are:
So just wanted to clarify a few things...
<I'm glad you did. You may want to increase your water quality
by filtering the water through Chemi-Pure. Do you have good water flow,
say about 10x your total tank volume? Tangs do prefer good flow rates.
You never mentioned your tank size, type of filtering, etc.,
makes it difficult to see the whole picture.>
<You're welcome. James (Salty Dog)>
Re: Regal Tang Breathing Problem 8/6/09

I did mention my tank size in the first email I believe,
<Yes, you did, sorry.>
however it is a 125 gallon with a 90 gallon sump and a 20 gallon

On a side note - The tang isn't seeing the Nori I am putting in so
I have moved it's position near it's hiding cave. I did place
the Nori on the sand but my turbo snail mowed it down first...
<If it is eating other foods, it may well recover. I have had very
healthy tangs that would not touch Nori and then some that did.>

Re: Regal Tang Breathing Problem 8/6/09
James.. you won't believe this....
<I bet I will.>
I saw my tang lining itself up in front of a rock and then.... you
guessed it.... flashing it's side on the rock a few times... I
can't believe it. I went 3 months with a fallow tank...
hyposalinity for my 2 clowns... Cupramine at the proper dosage.. and
<I'm certain the tank was clean after three months. The disease
was introduced into the system by some means.>
I certainly cannot tear down the entire tank again. Do you have any
suggestions as to what I can properly do to combat this? I know the odd
tang will scratch in real life and not have ich... but I'm not
certain with this one. I also know that skunk cleaner shrimp do NOT get
rid of ich under the skin, but could they help alleviate some
"annoyances" the tang has?
<Likely not enough to matter, as you say, they will not eliminate
the parasite but may alleviate some discomfort.
My suggestion would be to quarantine all fish and maintain treatment
dosage for 28 days.
This will ensure all hatching cysts will be killed. Copper/Cupramine
has no killing effect on the unhatched cysts and is why a 28 day
treatment plan is advised. As long as no fish are present in your
display tank, the parasitic infestation should cure itself in five
weeks. The ich parasites will die soon if no host is present. Any nets
or other cleaning tools should be sterilized in a solution of 20%
chlorine bleach and 80% water. We do not want to transfer any disease
into the display tank by way of implements. Have you read here?
Thanks for all your help
<You're welcome. James (Salty Dog)>
Re: Regal Tang Breathing Problem 8/7/09
There are only 2 possible solutions then. The hyposalinity treatment
either did not work (months ago),
<No guarantee's here, just a preferred first step.>
or the Cupramine treatment did not work. With that said, I did properly
calibrate the refractometer before I performed hypo on my clownfish.
They stayed in there for 3 months! Tank had no fish...
As for the new tang - I only held Cupramine for 15 days because the
bottle says 14 days and then get all of the chemicals out of the tank.
Are you saying that I should extend Cupramine treatment for 28 days at
<To ensure a total kill, yes.>
Other than that, I do not how to transfer the fish from the QT to the
main tank? I simply used a clean net (after Cupramine treatment) and
netted the fish, then let it down into the main tank. All of this of
course, under the presumption that the ich was killed off, and not
thinking ich could attach to the net during a transfer..
<The parasite can attach to and be transmissible by any wet object.
Is a good practice to make sure the net used is sterile before
transferring the fish back into the display tank. I say this only
because some folks have multiple systems and may use an infected net in
On a side note - the fish is still breathing slower, no more
scratching, and one tiny white dot I did see near it's tail is no
longer there (hard to tell otherwise.. you think you see little white
dots under the skin from certain angles) I'm not certain as to
whether or not it was ich because I have seen little particles stuck on
a fish for some time and then when the fish swims fast or changes
direction suddenly it clearly falls off. So I'm quite stumped as to
how the ich got back in the tank... sigh.
<I'm thinking you did not read the article I linked you to. Will
explain the life cycle of
the parasite. Also go to and read the links posted at the end of the
article, "Steven Pro's excellent ich articles".>
I think catching them all again would be very stressful? I also do not
know how to measure the Cupramine levels in the quarantine tank once a
water change is done.
<You must use SeaChem's test kit, it is designed for Cupramine.
The tests should be taken twice daily to ensure and effective dose is
There are different copper test kits on the market, some measure
copper, some measure chelated copper. Using one of the later kits can
result in erroneous readings.>
This could of contributed to the original HLLE on the tang.
I had gotten the copper level correct measuring with SeaChem's
test.. and then left it at that because I wanted to be certain the
copper level always remained around .5.
<Ah, good, you do have the SeaChem kit. Again, test twice daily to
ensure the recommended dose is present.>
If you could offer some advice that would be great.
<I had given you plenty of advice, read the articles I linked you
to, more reading,
less writing. There is no easy way out.>
I think for now since the tang is calming down.. I am going to leave
them in the main tank for now, using garlic and vitamins boosters... as
well as add a couple cleaner shrimp to help with some alleviation.. if
it doesn't re-occur then it should be alright... if not... I'll
have to net them again.
<OK, you're call. James (Salty Dog)>
Re: Regal Tang Breathing Problem/Not Reading/Remembering
So if I understand you correctly James in regards to transferring the
1) Net fish from QT
2) Place fish in bucket or some sort of transfer holding tank
3) Sterilize net (while fish waits in bucket)?
4) Scoop fish from bucket and place into DT?
<I've only mentioned item 3. You are making this more difficult
than it actually is. All I was eluding to is not to use a
"dirty" net in other tanks to prevent disease transmission.
We have already been through sterilization a few threads back. My
personal method is to keep my net in a container of Methylene blue and
fresh water for a few days after use, then rinse, and hang to
Wouldn't the parasites fall into the water (in the bucket from)
when being transferred from the quarantine tank?
<When the transfer occurs, there shouldn't be any parasites in
the quarantine tank if treated properly.>
Then when I scoop the fish from the bucket they would re-attach
themselves to the sterilized net? I'm not sure why I'm having a
hard time getting the right steps down.
<Same as above.>
I did read the article, perhaps just so much information at once :)
I was also under the impression that using Cupramine for over 14 weeks
would permanently damage the fish. Otherwise I would have used

Thank you so much for your quick reply!
My dad just got back from the store a while ago with a 2-gallon plastic
tank. I know it isn't much, but it is something. We have filled it
with the water from the main tank and have put Dory the Second in
(haha! Yes I know, the "second". I hope my parents will take
your advice on not getting a third).
<Please do put some pressure on them about not getting a third. This
fish really should be returned to the fish store when recovered. It is
much too large for a fifty gallon tank. Additionally, this two gallon
tank is not going to work for long term quarantine. Not only will the
water quickly become toxic from the waste produced by this fish, but it
is too small psychologically, even in the short term of a few weeks.

quarantining small tangs.>
Now that my dad has moved her to the Q Tank, we can see her better and
she's gotten worse from being up against that Power Head. Hopefully

recovered please either return the blue tang to the fish store, or find

Not looking good for my baby Blue Tang 5/13/09
I have a 55g saltwater tank. This tank has in it 1 Blue Tang, 1 clown
fish, 1 Scooter Blenny, (now) 1 damsel & 6 crabs. I got her on
Sunday, 2 days ago, and she did very well at first. Monday, I changed
20% of the water, this was the first water change I had done in the
seven weeks since I started putting fish in the tank. (Yes, big mistake
<Better late than never.>
I noticed that the blue yellow tail damsel I had in the tank until
today, was really aggressive toward my baby tang.
<Can be the nature of this fish.>
Sunday night she came up with one white spot, this morning she had
several. So I took her from the tank and put her in a container to go
with me to work, to keep and eye on her and go to the pet store for
them to see.
<Bad move here.>
After just one hour, she seemed to be much better. The spots went away
and she seemed happy. The manager of the pet store advised me to treat
her for ich. After much drama to find Ich-Attack, I put a small amount
in the container she was in
<I do not like the sound of this.."a small
and had my husband pick her up from my studio. He put her back in the
tank for me, as I thought she would be ok. I also raised the temp of
the tank to 78/80 and turned off the lights, as I was advised to by the
manager of the fish store. Now that I have taken the blue damsel out,
the spots seem to be subsiding.
Great, but she is very lethargic and appears to have a hard time coming
down from the top. She is breathing and will move if provoked. Any
advice on what I can do next? This tank system was a present for my 6
year old son (He wanted a killer whale and we settled on Nemo) and he
would be heartbroken if anything happened to her, as would I. (p.s. if

I just discovered your site and the amazing amount of information it

<Happy to hear you find it useful!>
I've spent the last eight hours reading through numerous threads
and I only wish I had found your site prior to purchasing a Blue Hippo
Tang; for now I realize the mistakes I have made up to this point, and
I could have surely avoided what might turn into a big problem.
<Ok, lets see what the problem is.>
I have a 125 gallon tank with a 25 gallon sump, mostly fish and a few
corals (Xenia and Zoanthids.) I never realized the importance of a QT
for new arrivals until now, you have truly enlightened me to the point
<Sadly, this is a lesson that is usually learned the hard
My question is regarding the Blue Hippo I purchased yesterday. Prior to
purchasing I did a little research (not enough) regarding
compatibility, diet, behavior, and general info on this beautiful fish
and decided he would be a acceptable addition to my tank. I read they
are more susceptible to marine ich than most so I was careful to make
sure he looked healthy before purchasing and was assured by the LFS
owner that the fish was quarantine for several weeks upon arriving in
and has been eating and healthy for 2 additional weeks since leaving
<Sounds encouraging so far.>
As he was ringing me up he went into long detail about drip acclimating
(which I always do for several hours already) and feeding the fish with
garlic soaked food to prevent an ich outbreak.
<I personally have doubts about garlic preventing Ich.>
Garlic was a new one to me so I wasn't sure what to make of it, but
the LFS owner swore by it and told me all the success he has had in the
past treating ich using garlic, so I purchased a bottle.
<Fair enough, it certainly cannot hurt.>
On the drive home the excitement of purchasing the fish started to wear
off and I started to get a little nervous. All this talk of ich and
preventative garlic and previous ich in the LFS was far different from
any previous fish purchase I have made and
it began to spook me a bit.
Upon getting home I got even more nervous when I noticed the Tang had
gotten kind of scraped up during his attempt to avoid being netted at
the LFS (he tried to hide by wedging himself under a rock.)
When I started the drip acclimation, I decided it might not be a bad
idea to try do something now to help prevent my new little buddy from
getting ich, so I thought adding some medication to the water might not
be a bad idea.
<It was a bad idea.>
Since it was 7:30 pm by this time I had to go with what I had on hand,
which left two choices: Copper or Acriflavine. I figured Copper might
be too harsh and stressful since he wasn't showing any signs of ich
and would be in the acclimation tank for the next few hours so I went
with the Acriflavine which I had used with success in the past on
Discus and was also for marine use.
<It does not treat Ich>
I added a few drops at a time to make sure he didn't negatively
react (in an obvious way) to the medicine until I got to about 1/2
teaspoon then used the incoming drips to slowly dilute the water during
the acclimation period of two hours. He didn't seem to be overly
bothered by the process.
This morning he was swimming around the tank getting used to his
tankmates and began eating the garlic soaked food enthusiastically,
however the scraping on body looked worse than it appeared through the
plastic bag upon his arrival last night. He has white patches
(abrasions not the salt grain look of ich) so I'm afraid he is more
susceptible to an ich breakout. I run a UV Sterilizer on the tank 24/7
and have never had any ich outbreaks in the tank since inception 4
years ago so I'm fairly sure there is no ich in the system unless
it has been introduced by the Tang. What has me concerned is that after
reading through your site I now understand the lifecycle of ich and
also the trouble it is to properly treat once an outbreak has begun. It
seems to me that garlic might offer an infected individual some benefit
in fighting off an infection but it would do nothing to eliminate the
parasite from a system once introduced, so if the LFS owners method of
ich treatment is garlic then I think I'm in trouble. Since the Tang
was in a tank with some coral and shrimp at the LFS there couldn't
have be any copper treatment in the system. On to my questions:
1) I read on your site that Acriflavine isn't an effective
treatment for ich but do you think a two hour bath in a highly
concentrated solution would have any effect at killing the ich parasite
if it were present?
It appears it might have removed his slime coat so the stronger
concentration might have made it to the target.
<Removing the slime coat makes the fish more vulnerable to
infection, so you do not want to damage the slime coat any
2) Since by the time you respond to this e-mail he'll have been in
the tank for over 36 hours is there any reason to try to remove him now
or am I past the point of no return.
<I would not move or stress this fish further unless you actually
see signs of Ich or an infection from the scrapes.>
I thought about trying to remove and quarantine the Tang today but I
have around 150lbs of live rock in the tank and catching him would more
than likely be impossible and only stress him further and probably lead
to more abrasions so I decided to write to you first.
<I agree, leave the fish be and observe. With a good diet and good
water quality, it should heal up fairly quickly.>
3) If removing him is your suggestion do you have any tricks to netting
Thank You so much for taking the time to respond, and thanks again for
the wonderful site. I'm confident with your sight as a reference
I'll avoid making many truly unnecessary and preventable mistakes
in the future.

Re: Hippo/Regal Tang Health: Quarantine
Thanks for the reply Mike,
<Hi Alex, no problem.>
I guess my most pressing concern is trying to avoid introducing the ich
into the system.
<Ich is already in your system and has been since day 1, the trick
is keeping all of your livestock healthy enough so it does not
Since the article on the lifecycle of ich says that it spends seven
days on the host fish growing and multiplying before popping and
<This is true.>
I was curious if I have an opportunity window of seven days to remove
the Tang if he starts showing signs of ich. OR, if it's already too
late and if the ich was introduced via the Tang is already there and
removing him would be of no value.
<Removing the fish would be of no value at this point, unless it
actively shows signs of Ich or starts showing signs of
Another question, sorry!
My hippos has ich, as does my Foxface etc.... I assume everyone is
screwed at this point.
Anyways, I was told by everyone that NO MATTER WHAT Hippo tangs will
get ich over and over. NO MATTER WHAT!
<... No, not so>
So I am thinking of the best course of action right now. I dread the
thought of leaving the tank fallow for 2 months, and then having to buy
another tank to treat the infected in (smallest size?) I have a 29
gallon in my crawlspace right now but with my small house I am
wondering where the heck I will put it and will it be big enough?!
I will be very upset if I do the whole treatment of curing the fish
while fallowing the tank and then I put the hippo back in and it gets
ich again as I am told that is what will happen. I know you are
thinking this is what you get for not QTing, but I did
QT. My tank is new (not new to me but brand new) and these are the
first fish added after QTing. I don't know where I went wrong?
I am so pissed right now. I wanted a really nice system and bought a
super nice looking stand, bubble king skimmer180, 2 Vortech MP40's,
etc... My total must be near about 8000.00 right now. I feel that if
the ich knew that they would just die a horrible death and leave me
with a nice tank. But NOOOOOOOO, that is not the case. So I guess my
question to you is if I go through the hassle of QTing/ medicating
again! will the hippo just get ich again when added back to the tank
starting this whole saga over again for me?
<Is possible... however... there are some better approaches to
treatment that might work>
Should I flush it down the toilet now? ha ha, not really. And what do
you find the best treatment for ich?
<Heeeee! Sorry... Maybe quinine for you here:
Hyposalinity or copper, and if copper what brand is best to use? Is
there a copper that is a tad safer?
<Mmm, yes... please take a gander at WWM here... chelated varieties,
brands... matching test kits...>
I want to make sure I kill the ich dead, but not the fish! I am so
sorry for the rant, you must get tired of all the questions
from people. I have Bob Fenner's book on order, I have a few sw
books already but the more you can read the better I figure.
<Mmm... perhaps. Gots to toss in the proviso that we are indeed
time-limited, task directed only to extents>
Thank you so much for your eagerly anticipated answer!!

Re: Ich 03/26/09
Thank you very much for your answers. Sorry again for the rant. Who
knew this could be so frustrating???
<I'll admit to knowing the likelihood... but, am hoping we can
help you get beyond this trouble...>
I am going with Seachem's copper treatments with the matched up
copper test. Hope that does the trick for the sick fishes.
Can't wait for your book to come in the mail, should be today!

Seemingly ill Blue Surgeonfish 3/25/2009
Good day WWM crew,
I have a concern regarding one of my long time fish and I was hoping
you could help me with some ideas.
The problem is regarding my pacific blue tang / Blue Surgeonfish /
Paracanthurus hepatus. The fish physically looks healthy (no odd
markings, scale problems, bloating, discolouration, or fin problems)
and yet it is acting as if it will be dying soon (swimming upside-down
in quick bursts and mostly laying in vertical stillness in corners of
the tank; as well swimming in strange circular patterns when it appears
to get spooked).
<Yikes... I hope I am not too late...>
I noticed that approximately two months ago, the fish became very
passive (basically overnight) usually staying in the back corner of the
tank and only coming out to eat. Due to its healthy physical
appearance, I was hoping that the fish was doing this on a temporary
basis. It kept this act up until the other day (which I did not like,
but I could not think of anything that would be wrong with it). It was
about a day or two ago that it started to act very strangely as
Any help regarding this would be much appreciated. I feel that the fish
may not recover, although I still hold some hope. Please note that as I
mentioned above, the fish physically looks as healthy as I've ever
<Something is very wrong if this fish is inverted... I would be
checking your dissolved oxygen, or better, just executing a large water
change, lowering your Spg, adding circulation, surface agitation...
This tang is easily mal-influenced by low DO... this is likely the
problem here. Bob Fenner>
72 Gallon tank with 1/5th live rock and about half a dozen small-medium
corals (none with strong stinging capabilities).
5 fish in total including 2 clownfish, an angel fish, a yellow tang,
and the pacific blue in question. The tank has about 3 hermit crabs, 5
snails, and 2 brittle stars.
Water quality is not perfect but is fairly good. It has been fairly
consistent for over a year.
The tank has been running with very few changes for around three-five
The surgeon fish in question has been living well in the tank for over
two years now. It was about 5cm in length when it was added to the
tank. It is now roughly 12-15cm in length.
In terms of lighting, the tank has 2 150W 10k metal halides that run
for approx 9h a day, and two 96W actinic power compacts that run for a
total of 11h per day (on 1h before the halides and off 1h after the
Tank temperature is maintained around 78F + or - a degree through the
course of the day.
Filtration and water flow in the tank includes: A UV sterilizer,
protein skimmer (always on), canister filter (always on - currently on
a variable flow output, but had been maintained on a constant flow up
until a month ago), and a pump (always on) for additional water
Fish diet currently consists of two types of flake food (not the best
diet I know...). Those are Prime Reef Flakes and Formula Two Flakes, by
In terms of tank deaths, it has been over a year since I've had a
fish die, and about 6+ months ago a clam I had in the tank died
I believe that about covers the situation. Any thoughts would be much
