Sick Clownfish, New System Stocking Problem - 2/13/07
Hi Guys
<Hi Darren, Brenda here>
I have a 50 gal (US) corner tank, 35-40 lbs live rock, water turn of 900
gal/hr via 3 p/heads and filters, canister filter (Fluval 404) with coral
gravel as filter media all running for 6 weeks or so, 1 Mertensii Butterfly
3", 3 blue/green Chromis all 1", 1 Midas Blenny 3" and a very sick looking
Common Clown 1" (plus a cleaner and a peppermint shrimp, 6 hermits and 3
Turbos). I recently introduced a 3 inch Bubble tip anemone also.
<Your tank is overstocked for a 6 week old setup. It is also recommended to
wait a minimum of 6 months before adding an anemone.>
Temp constant around 77, SG around 1.24,
<1.024??>
pH 7.7-7.9, no ammonia or nitrite and nitrate around 13-14 mg/l.
<Temperature should be 79-81 and salinity should be 1.026 for an anemone
with pH at 8.2-8.5. Nitrates, they need to be at zero.>
Now to the Clown which I have had for about 3 weeks, in which he has been
very bright, alert and eating well. He has been in hiding for a day or so,
I thought it was because I had to make some adjustments to the live rock and
he was startled. He came out for a swim last night and looked in good
health, then this morning I came in and he was lying on the bottom,
breathing heavily and trying to swim but struggling. Since then he has
tried to swim into a secluded area beneath the rock and continues to breathe
heavily. I can't see any slime or white coloration that would indicate
Brooklynella. I did recently lose a Regal Tang to some unknown disease
(rapid weight loss and loss of appetite, stomach swelling and some
accompanying white spot).
<Did you quarantine for 30 days before adding to your tank?>
Could the clown have something similar or has he maybe tried to inhabit the
anemone and it stung him badly, or is it something else perhaps. Please
help, I really don't want to lose another fish in quick succession.
<Bubble Tip Anemones do not sting clownfish. The Regal Tang’s unknown
disease could have infected the clownfish. However, your high nitrates and
overstocked new setup alone could cause this also. I do suggest placing the
clownfish in quarantine and water changes to get your nitrates down to
zero. Please read here for more information on clownfish diseases. http://www.wetwebmedia.com/clndisfaqs.htm

Yellow angel in a bad way. Heat Stroke... 2/11/07
Hi guys,
<Hello.>
firstly I would like to say that your website is great.
<Thanks.>
My name is Janet and I am a novice aquarist.
<My name is Adam and I'm an alcoholic....woops wrong place and time
(kidding).>
I have a 200litre tank about 3 months old. Levels are ammonia 0 Nitrites
1ppm and nitrates 10ppm at present.
<Mmm any present nitrites are no good...could be just a test kit issue
though.>
Just introduced a yellow angelfish 4 days ago and today my chiller has
stuffed up and temps rose to 28celcius.
<Uh-oh.>
Didn't realize there was a problem until i saw the fish lying on the bottom
of the tank on his side. Have cooled it down using frozen bottles of water
but he is not looking good. Other fish in the tank are 2 tomato clowns,
1blue tang, 1 coral beauty, 1 reef butterfly and 1 blue wrasse. Is there
anything I can do to help him?
<I would move the specimen into a stable isolation and keep it there he
exhibits normal behavior...especially dietary wise...and do find a way to
keep the display temp. stable.>
Thanks heaps, Janet.

Velvet Clown... Mmm, no... env. 2/4/07
I'm writing in sort of an emergency. I'm new to marine aquariums, and two of
my fish have recently died and I'm trying to save the last one.
The three fish, a damsel and two clowns, were both in a dirty, 20-gallon tank. I
switched them to a fresh 10-gallon tank about a week ago,
<Too small...>
following all the instructions about acclimating them to the new system
(although I did not dip them between tanks, I've never done that before). The
damsel immediately developed a pop-eye, lost interest in food, and died within
the week. The smaller clown began swimming erratically two days ago, and now is
lying on the gravel, breathing very hard and I assume he is not going to make
it. The third clown has lost interest in eating as well, and he's developed a
sort of yellow powder on him that, after reading your site, seems to be a
symptom of velvet.
<Mmm... environment>
I installed an appropriate size-heater on the tank, and have been fishing
through with a small net to remove any excess food, so I don't understand what
I've done wrong to make water conditions so bad.
<... nitrogenous waste bottlenecking>
I did transfer a handful of gravel from the old tank to the new one; my teacher
recommended it to establish good bacteria in the new tank,
<This and time... likely 4-6 weeks...>
so I don't know if that gravel may have been the trigger. The new tank also has
a heater (the old one did not) set to about 70 degrees.
I read on your site that a freshwater dip could help treat the velvet, but I've
never done a dip before and I'm scared to try something that could overstress an
already stressed fish.
<Good>
Could you give me some specific instructions on how to do a freshwater dip, or
tell me about a more effective remedy for my problem?
<Test kits...>
(Note that I also have three small marine snails in the tank) I'd really also
like your opinion on what's going on in my tank to make my fish so sick; if I
ever get new ones I want to make sure they don't have to go through this. Is
there a cleaner organism I could add to help water quality? The tank's specific
gravity is about 1.017
<Too low>
(if the plastic hydrometer is accurate) and I don't know the pH. Thanks for your
help.

Cloudy <Asfur> eye problem
1/16/07
Hello Crew:
<Eric>
Happy 2007! I would like to ask for your expert diagnosis of this
particular case... hope you all can help me a little bit.
please see the attachment.
<See it>
I have an Asfur Angel fish, QTed it for 20 days and was put into my
FOWLR 5 days ago. 3 days later it developed cloudy eye, so I first
dipped it with FW and formalin+paraguard.
<Didn't I respond to this recently? This problem is unilateral correct?
One-sided?>
During dipping, I noticed 15-20 tiny little circular "stuffs" appeared
on both eyes, and also behind the fins next to the gills, these "stuffs"
are circular, about3-3.5mm across, like hanging onto the fish. I scrub
most of them off the fish gently
<You're joking... please tell me>
with a toothbrush in the dips, but the cloudy eye was pretty severe. I
could see 3-4 of them attached onto that eye.
for the next couple of days I have dipped it once a day with
formalin+paraguard in FW. all other "stuffs" have gone from the fish's
body but the cloudy eye still remain, although it is getting a "little
bit" better, I would like to know a couple things:
1. what are those circular stuff? and is it contagious?
<Is highly likely the fishes cornea... please stop scraping, dipping>
2. what would be the best remedy to treat the cloudy eye? I am currently
dipping it once a day and lowering salinity in QT... is there additional
things I should be doing?
<To do your best at providing an optimized, stable setting... nutrition>
3. for ID-ing disease, can you please suggest me some readings/books and
a place for me to purchase a microscope?
<A QX5... see the Net... and Ed Noga's Fish Disease, Diagnosis and
Treatment to start with>
thank you very much!
Eric
<No more scraping, dipping... or I'll hope you're reincarnated as a
pet-fish! Bob Fenner> |

Koran Angelfish melting like the wicked-witch
1/13/07
Hello:
<Hi Beth, Graham T. with you tonight>
I have about a 2.5 years old Koran Angelfish that over the past year has
slowly been losing it's color and fins. It has lost most of its
fins but is still able to swim around and eats well.
<Sad story so far...>
I have had the water checked and is fine.
<Mmmm... fine. I read that a lot here on WWM. Usually closely followed
by, "Fine is a relative term. Can you be more specific?" You need to
include some numbers here, and invest in some kits for more
accurate/frequent testing.>
It is a 55 gallon tank with only a Clownfish in with it. What could be
causing this and is it treatable?
Attached is a picture.
<Oh my GOD! That poor fish... what a shame. A whole year he has been
rotting away like that? Let me start with what I see in the background,
and speculate with what I don't see. Plastic plants and the large shell
are actually poor choices for decor in a mini-reef. (Big shells are
known to cause more problems than their attractiveness is worth.) Was
this setup based on a freshwater-to-saltwater conversion? If so, you may
not know that there are many freshwater substrates and decorations that
are totally unsuitable for marine use, due to saltwater's corrosive
nature. To maintain a successful marine aquarium, you need to have some
basic test-kits to allow for frequent and reliable testing of water
quality, mainly ammonia, nitrite, nitrate Ph and specific gravity. Many
are discouraged from the hobby by the impression that you need a
doctorate in chemistry to achieve this success. While the degree
certainly gives you a clean grasp of the fundamentals (and more) of
what's going on in you tank, the basics are all you need to know.
Remember where these animals come from: clear pure waters. Please reply
with any specifics you are able to provide about your system including
filtration, skimming, presence/amount of liverock/live sand, frequency
and composition of water changes, and ANY test results you have,
including but not limited to salinity (specific gravity), ammonia,
nitrite, nitrate, and Ph for starters. I want you to get the fastest
turn-around on your replies from WWM, so I grabbed this email as soon as
I saw it. *BUT* I am not the best qualified crewer to answer questions
about treatment of pathogens, so I may hand this off on it's return if I
suspect something other than environmental by your reply. I apologize
for my shocked response to your poor angel, but it seems that a year of
this wasting away is just bit long and, frankly, awful.
-Graham T.>
Thanks,
Beth |

If Adding Salt, One Must Also Add Knowledge... 1/11/07
Hi
<Hello John, Mich here.>
after owning and maintaining a freshwater tank for three years, I decided to try
a marine tank.
<Welcome to the briny world.>
I set it up, and did what I think was doing everything right.
<How did you know what to do?>
But about a week later, every living thing in the tank died at the same time.
<Sorry for your loss.>
Six creatures died.
<That's a big loss.>
I was wondering if you could tell me what happened.
<Well, more information would be helpful, but with what you provided, my
assumption is that you did not cycle your tank and your animals died because of
this. Unfortunately, their death may have been caused by your ignorance. The
concentration of toxic ammonia would be peaking after about a week, which would
fall into you time frame. Nitrite, which is also toxic to livestock would soon
follow. Generally it takes at least a month to go through this process. How
much reading have you done? There are many differences between freshwater and
saltwater aquarium keeping. If you want to venture in the marine world, you
will need to make a big commitment to educating yourself to the system
requirements and the livestock in your care. My first recommendation to you
would be to read a book called "The Conscientious Marine Aquarist" by Robert M.
Fenner. If you only buy one book this is the one to buy. There is also a
tremendous amount of useful information on this website. Here is a list of some
suggested readings. When you've finished the list, please realize that this is
merely drops in a bucket and that you must continue to educate yourself to the
complexities of this hobby.

Maroon Clown Fish's Face is Rotting Off!?! Env. dis. 12/19/06
Hello-
Looked through questions on your site and couldn't find one that mentioned this
particular problem.
I have a pretty large (4-5 inch) maroon clown. He was healthy as could be in my
55 gallon with only one other resident (a porcupine puffer).
<Incompatible... and not enough space for a Diodontid...>
Tank parameters are fine, feeding and breathing habits, all fine. I noticed what
looked like a gill infection about 2 months ago. It seemed to be spreading from
the inside out in sporadic bumps. They open up into cauliflower like growths,
and then he loses skin around the area. He is now literally missing skin and the
rest is shredded and torn up.
<Environmental in cause/cure>
In the beginning, I took him to where I got him and asked their advice. They
said it was an infection and to treat him in a hospital tank.
<... dismal>
Which I did, for a week. NO improvement. I treated him with an anti-bacterial.
Then gave it a rest and treated him with an anti-parasitic.
<Why?>
A freshwater dip merely stressed him out, and didn't change anything, either.
Putting him back in the main tank seemed to help him out for a couple days, but
alas, he is now worse than ever. He is swimming around and eating and breathing
fine. No lethargy or any other signs of sickness. I am thinking this is just a
chronic viral infection.
<...>
Could it be that he got this from eating a bad clam that I had unknowingly put
in the tank? How can I help him out? I don't know what else to try??
<What re your set-up, maintenance, water quality tests, testing? Please read

Power Outage/Oxygen Loss - 10/28/06
Hello,
<<Howdy>>
Last weekend, a fuse blew in the room where I keep my aquarium. My
girlfriend came home from work to find the temperature at 73 degrees (I
keep it at 79) and all the fish gasping near the surface.
<<Lack of oxygen...either the power had been of for quite some time or
the tank has an excessive bioload>>
She turned everything back on and the fish came down from the surface
and the temperature gradually rose back to normal (I realize that a
slower increase in temperature would have been preferable, but I wasn't
available to deal with the situation at the time).
<<I see>>
I came back after being out of town for 3 days to find that my pygmy
angel had been killed by ich (no surprise) and my red general star was
pretty much just a pile of goo.
<<Hmm...I wouldn't think a temporary drop to 73-degrees to be all that
problematic. I have heard of/experienced lower drops during extended
power outages without loss of life>>
What I'm concerned about now is that my snowflake eel and my Sargassum
frogfish are both still very lethargic and not eating (the temperature
drop/rise happened 5 days ago). The eel barely comes out of the rocks;
but when he does, he seems very weak and sluggish--and not at all
interested in any food I offer. The frogfish has been laying around on
the bottom--often on his side--gasping regularly and not eating. Is
there anything I can do besides sit and wait at this point? How long
should I expect for it to take for them to return to normal if they're
going to recover?
<<I think there is something else wrong here. Have you performed any
ammonia/nitrite testing? The fact your fish were gasping at the surface
suggests massive oxygen depletion, I'm betting your biological filter
was severely damaged and the fish are being poisoned. A series of large
water changes and the addition of a bacteria culture (either seeded from
another healthy system or a commercially available product) should
help>>
Also, the frogfish looks pretty uncomfortable; is there a point at which
I should consider euthanizing him rather than letting him starve to
death or suffocate or something?
<<Maybe, but hard to say when...do try the water changes/bacteria
first...and soon!>>
The temp is back to 79, SG is 1.024, alkalinity is about 130, pH about
8.3, nitrates <10.
Thanks.
<<Regards, EricR>>
Nano Reef Emergency 10/27/06
Dear Mr. Fenner,
The heater in our 20 gallon nano reef tank malfunctioned three days
ago. The temperature went from 82 degrees to 95 degrees. We noticed this in
the morning. As soon as we did, we took steps to correct it. We replaced
the heater and floated a bag filled with ice in the tank, as instructed by my
LFS.
<Mmm... better (unless organisms were obviously dying...) to let the temp.
return slowly...>
I had to leave immediately afterwards, on a previously scheduled 3 day
vacation with my parents. The tank was left in the care of a person who is
knowledgeable about salt water aquariums. Upon my return, I found almost
everything dead or dying, except for my two ocellaris clown fish and a yellow
tail blue damsel fish. I have yet to see the Firefish.
<These are inappropriately placed here>
My question is, is there anything I can do to save any of the corals? Here is
a list of corals that I have.
1 pagoda cup coral
1 Lobophyllia
1 hairy mushroom
1 xenia
several small colonies of star polyps
several small mushrooms
Most of the corals look beyond hope.
As a warning to anyone who has or is thinking about buying a heater.
DO NOT GET AN AQUATIC GARDENS BRAND!!!!!!! I will everything I can to save
any of the corals, considering the combined value of them exceeded $400.
I appreciate any help or information that you can give me.
Thanks for the help,
Michael

Coming to my question - I have recently added 1 yellow wrasse , i was
acclimatizing it in a container above my tank , when i returned i saw the
container empty!!
<Jumped!>
i searched in vain that whole evening in the nooks and crevices of the tank ...
i was just praying that the yellow wrasse may have jumped in the tank while
acclimatizing and survived... The following morning the yellow wrasse appeared
and i was glad ..it was eating too! it was swimming the whole day until it
disappeared again by evening (even though the 2 NOs PL lights were on) it didn't
appear in early morning today during my feed time....am worried...am in office
now and hoping to see it swimming when am back home late evening. Question 2 - I
had also purchased a cleaner wrasse which was also introduced simultaneously,
<Labroides sp.? Poor choice>
it never took into hiding and kept swimming the whole day till it vanished in
the evening 30 minutes after the yellow wrasse vanished. It hasn't appeared
today morn whilst feeding... Is this normal?
<To die mysteriously? Yes>
In case they hide in evening how do they get to know its evening considering the
lights still on! Lights MH and 1 PL on from 7 am morn to 7 pm evening and post 7

10/3/06
Hello Bob
I'm a new comer with a query. I have a small tank of 38 litres, 2.5 kilos of
live rock,
1 anemone about 3inches circumference (called Fats),
1 bubble anemone 1 1/2 inches circumference (called Mr. Willys)
<Anemones are largely incompatible cross-species... no matter what they're
named>
1 star fish (called Miss Movie Star)
1 ocellaris clown (Snoopy 2.5cms long) for this time. but only 2 months ago
added Fats because he never went in to the Mr. Willys).
Once I got Fats he seemed happy and complete so after a couple of weeks I added
one tiny domino damsel (Spots 1cm long),
<Let's call him Mr. Biggee, the Terminator>
which he constantly chased around the tank.
Snoopy was getting more and more aggressive so I purchased another ocellaris
yesterday (Tony - 2.5cm long).
<Too much...>
Now Tony is the boss of the tank chasing snoopy away from Fats, they locked jaws
fighting for the first few hours on off yesterday. Today doesn't seem as bad
but Tony chases Snoopy constantly and they both do this twitching movement on
there side (Snoopy does it more) Tony is forcing Snoopy behind the rock and
then returns to Fats only for a few seconds then hangs around Snoopy and back
and forth it goes. Snoopy is a bit ragged today and doesn't look happy. Snoopy
tries to return to Fats but Tony is on to him and doesn't let him stay for long
and then with the twitching again. Is Tony going to get him or what's going on.
Thanks Terri-Anne

Star Polyp Color Loss... Allelopathy in a crowded, small, mis-stocked nano
9/2/06
Hello Crew:
<Richard>
I am writing to you concerning a very odd star polyp issue. First, my tank:
10Gal Nano - 2 inch sand bed, 17lbs live rock - 8 months old
55 Gal Power Filter (set 1/4 on) - run one side with carbon constantly
1 20 Gal Power Head
Heat at 78 - fluctuates 77-79
96Watt Aqualight 50/50 PC
Weekly - Biweekly 1 gallon water change
C-Balance every 2-3 days
<With testing...>
Liquid Calcium every 2-3 days (alternate from C-Balance)
PH Buffer 2 times/week
<Dittos>
Ammonia - 0
Nitrite - 0
Nitrate ~0
PH 8.2-8.3
Calcium - 300-350 (a bit low but it just seems that this tank stays low)
Phosphate - 0
Mates:
-Percula Clown Fish
-Linckia Star Fish (Didn't realize at the time that 10 gal is too small - I
think he is hungry and appears to be shrinking, but I'm cycling a 37 that he can
move into soon).
<Still too small...>
-Blue Maxima Clam 2"
-Teardrop Clam 2"
<... these Tridacnids are misplaced here>
-3 Blue Hermits
-4 Astrea Snails
-Xenia - 2 types
-Button Polyps - many colors
-Ricordea - 3 heads
-Mushrooms
-Toadstool Coral )Getting big now!
-Star Polyps
I feed the clown flakes - he will eat out of my hands which is cool. I feed DTs
twice per week for the clams, and feed frozen Cyclop-eeze to the star polyps 2
times/week.
Absolutely everything is the tank is growing at a great rate (except the
starfish).
Now to my question: The star polyps were given to me by one of the guys at my
LFS (just tore off a piece growing on the sand!). The polyps have white centers
with long green tentacles. The underling color is brown. Ever since I've had
them, they have grown at an amazing rate.
<... dangerous in such a small volume>
They have never had any problems opening fully and continue to grow like crazy.
However, over the past 3 months, the green color has been disappearing from the
tentacles (leaving them brown). Now the green color is nearly completely gone. I
read one forum article where a respondent stated that it may be that if the
animal isn't being fed enough that the symbiotic algae was taking over the
feeding chore - providing energy for the coral and as a result, changing the
pigment through sheer reproductive growth. This seemed to make since and I
increased feedings of Cyclop-eeze to no avail. Any ideas would be appreciated.
Thanks for the great articles and FAQs.

Not Very Successful, no apostrophes? Small reef, mis- and over-stocked,
about to crash 8/29/06
Hello.
I read your web page frequently. I've had a 20 gallon saltwater aquarium for
approx 10 months. I've had many things occur that I wasn't prepared for. After
battling everything thus far the tank has zero nitrates, zero ammonia, zero
nitrites, low phosphates, never tested silicas, 350-400 calcium, 12 dKH, 8.2 ph,
salinity 32, and temp stays at 78F. I change the water weekly with 20 percent DI
water and Red Sea salt mix and Prime.
It has 65 watts of total light from two 20K with one actinic T5s and is of the
shallow variety.
<?>
The lights are on for 10 hrs a day. I think I made a mistake in buying the
SeaClone150 Skimmer.
<Fine for this small system>
Of course I only discovered that reading your web page AFTER I bought the thing.
It doesn't really skim anything. Its better at making a protein layer on the
surface that must be broken down! Which I do. Also an AquaClear hang on the back
filter that has mechanical filter, carbon (in two weeks out 2 weeks), and poly
fiber. Two 600 powerheads provide the current.
It has: toadstool, mushrooms, sun polyps, yellow polyps, brown polyps,
frogspawn,
<A bunch of Cnidarian species for such a small tank>
feather duster, royal urchin, peppermint shrimp, brittle sea star, hermit crabs,
snails, and amphipods. I've had flatworms, eradicating them with
FWE. Unfortunately I found your site after I had set up the tank, so I made
another mistake of using crushed coral as the substrate, although it
isn't deep.
I have 21lbs of live rock.
I have a red slime issue. Mostly accumulates on the substrate in high current.
I've used the medication and followed the directions with no luck.
Slows it down, but it builds back up. Also hair algae. It doesn't grow tall on my
live rock even though I can see a green hue on the rocks.
<These algae issues are thoroughly gone over on WWM>
It also mostly grows tall on the substrate and some small rocks.
It looks like the toadstool is synching its stem and receding from the bottom.
<Allelopathy...>
Its polyps go in and out and it changes shapes frequently.
The frogspawn recently started dropping arms and I noticed the skin around the
branch was receded in slightly but still hanging on. That was a few days ago and
it has ceased dropping arms and doesn't expand too much except for a big stinger
from the middle. Im currently setting up a hospital tank.
<Not what's needed... see below>
I turned down the current around the frogspawn to none.
The snails are dying, they just stop moving. I put 8 in along with 4 hermit
crabs to help with the algae. All the other creatures are fine.
<Mmm, not for long>
The mushrooms even multiply frequently, I see molts. The feather duster has also
lost and regrown his feather twice, is that good or bad?
<Indicative>
I feed DTs every other day by using a baster and squirting the corals directly
with no flow.
Also using Reef Plus and Reef complete. What am I doing wrong here?
Thanks!

I have had this tank up and running for almost one year and have had a pretty
good deal of success with very minimal deaths. All of which were early on! The
Coralline Algae growth is beautiful and not overbearing as I've read it can be
in some systems. I don't have many of the issues that I read about such as nasty
hitchhikers, temperature spikes/drops, Cyano (Red Slime) but I do get the
occasional brownish/orange algae on the sand bed. What algae is this and what
will reduce it?
<Very likely mostly BGA/Cyanobacteria... see WWM re>
As good as things have been I still have a few issues that sprang up out of
nowhere. Wouldn't you know it. the winds of change are upon me and recently I
have been experiencing the fact that I cannot keep the water quality where I
want it! Although the parameters NEVER exceed what you see listed above, they
tend to hover around that same mark. I thought it may have been overstocking
<Is mostly... that/this and insufficient filtration>
issue but that was never an issue before and I have had these fish for over 6
months.
<They've grown... and your hard substrates have lost surface area and
solubility>
My maintenance schedule is very regimented and I've always follow what was
working for so long but I think that I need to add or remove some steps and/or
additives because the parameters are just not quite right and may be
contributing to some other issues. Can you please add some tips about what I
written that may or may not be working for me based upon the specs I've listed
above or below?
<Mmm, what you really need is a much larger system... with a sump/refugium...
much more live rock...>
I recently read on your site that keeping Yellow Finger Gorgonian is not
recommended. I was shocked to read this given the number of these that are being
sold everywhere here in South Florida.
<Easy to collect nearby>
How sad that we are raping the sea of these beautiful creatures to put them to
death this way. I was reluctant to buy this coral
<Mmm, not really a coral... a Sea Fan>
to begin with after my experience with a Purple Frilly Gorgonian dying but after
I lost the first one and now am worried about losing the second, it is fair to
say that again, you were definitely correct. These are not very easy to keep and
I fear that may be impacting my water trying to feed this guy. Reading that
they are doomed to death was good to know but between him and the Carnation
Coral (also struggling, I have spent a lot of time feeding recently and still
cannot get positive results from these two. Are there any specific foods you
would suggest and/or feeding schedule they should be on that are not already
being fed?
<Mmm, you are doing very well to have kept these this long... likely in part due
to the "insufficient filtration" along with your diligent efforts at feeding.
Again... a refugium is the single best chance for improvement... along with
larger quarters>
Additionally, I have some polyps (considered in the hobby as "easy to keep")
that are starting to wither away also. Is this some sort of cyclical occurrence
being that they are the oldest ones in the tank?
<To some extent... but more/mostly "succession"... with "winners" winning out
over "losers" allelopathogenically>
I cannot pinpoint what the issue is but I am losing Brown Buttons Polyps and
Star Polyps and cannot revive them either. My water parameters are not that
"off" the desirable levels so it is even more difficult to pinpoint. The Torch,
Mushrooms (still spreading like crazy), other newer Polyps, Brains, Blasto
Merleti, and Sponge are doing really well and opening up quite nicely.
Do you have any suggestions about what the issues may be?
<Yes. Please read here:
http://wetwebmedia.com/cnidcompfaqs.htm>
Is it water related in your opinion or could lack of adequate lighting be an
issue?
<Mmm, a few things... read the linked files above the above referent>
The lights in the current fixture are 50/50's and produce 130 watts but are
about 11 months old. Could they have lost their effectiveness?
<To some extent>
Could it be lack of proper flow seeing that I use 600gph and 400gph Maxi-jet's
only?
<Not nearly as important a factor as the size/volume, mix of organisms...>
I was thinking about increasing my flow by ditching the two lesser flow
Maxi-Jet's and getting 3-1200gph Maxi Jet's instead with those rotating flow
tips that simulate tidal changes...any suggestions about this?
<Mmm, I would not do this... too likely to have no discernible improvement...>
Note: I recently started using water from Glacier (you know, the Clear Blue 5
gallon drinking canisters) bought at a vending machine in my local grocery store
to do water changes and mixing in the Instant Ocean salts. I did this instead of
using my home water (home water was found it to be loaded with undesirables).
Although the sign on the machine states that it is filtered RO/DI water, not
kept in copper vats, UV sterilized, etc. coupled with the fact that all of the
tests I ran on it came back favorably, I'm wondering if this water is a problem
somehow. I am now considering using seawater collected from a local reef (about
10 miles off shore) and then sold at a very reputable dealer here in Florida
even though the cost is considerably higher per gallon and they are located (as
Shrek would say) "Far Far Away, Donkey!"
<... see WWM re this issue as well. Not suggested>
Do you have any suggestions about using seawater or any experience regarding the
Glacier water? There is also an "oil" slick collecting at the top of the water
and I don't have anything to break the surface and Maxi-jet's just aren't good
for this. Should I employ a surface skimmer or some other agitator to better the
gas exchange and could this be a contributing factor?
<All covered on WWM... the search tool, indices...>
Lastly, I just ordered 4x96 Orbit Power Compacts and am going to get rid of the
2x65 Satellite's. The new lights have been well reviewed by what I've read and I
anticipate that they will be much better than the old lights.
<I predict they will likely bring about a crash in your system... You need to
READ my friend... you have an extremely incompatible mix of life (the Cnidarians
mostly)... and changing the light make up will shift too much too soon the
metabolism of some over others... resulting in their poisoning the less
favored...>
Those were good at keeping everything healthy and alive but nothing seemed to
grow. By the same token, most of my corals have done fairly well with them so
I'm a little scared to change. I don't have heat problems generally associated
with hotter, higher wattage lighting units and have not needed a chiller as a
result. Do you think that I may have heat issues now with the new lights?
<Almost assuredly>
How about the algae. will it be harder to control with stronger lights? Oh yeah,
can I grow any SPS or clams so long as they are high in the tank?
<...>
I do realize that there will be an acclimation period for the corals to adjust
to the new lighting but am not sure how to go about acclimation due to the fact
that the tank is very meticulously "aquascaped" and corals have started growing
on rocks that I cannot move without ruining the design. I absolutely care more
about the fish and corals thank I do the rock formation but it was a PITA to do
it this way and I really don't want to take it down if at all possible in fear
that I can never get it back this way. Are there any other methods to acclimate
the tank to the new lighting without having to move too many corals or depriving
them of the amount of light they need in a given day? Will reducing the number
of hours per day the lights are on for a period of time allow the corals adjust
and if so, will you please offer any tips about how long I should run my new
lamps and in what intervals. Also, please note which corals should be moved or
shaded. I don't want to shock my critters or corals by almost quadrupling their
lighting overnight. Do you have any recommendations about how to proceed with
this upgrade?
Thank you so much for your assistance!!!

Gerald V. Catalano

*~60+ lbs of LR
*~3-4 inch live sand bed
Filtration:
*10% water changes every week.
*Rena XP3 canister filter (not my favorite, but I was in desperate
need of an upgrade with short notice... would love to upgrade to a
sump system with a refugium, but my tank's stand is separated down
the middle underneath)
<Mmm, might consider placing somewhere else...>
(rated at 350 gph)
*MarineLand Emperor 400 hang on filter (my original filter during
initial LR cycle... still installed in addition to the Rena) (rated
to 400gph... yeah right...)

*NOTE - lack of a skimmer... will soon be getting a Aqua C Remora
hang-on skimmer. I've heard good things.
<Good>
Lighting:
*Coralife AqualightPro - 2x 150W HQI + 2x 96W Actinic + Moonlight
LEDs
*HQI's are on for ~10 hours per day
*Actinics are on for ~1.5 hours before and after the 10k's
*Moonlights on all night (is this correct???)
<Is fine... I would leave on for the hours you're about mostly... if
there's some other minimum light otherwise present in the room>

on the substrate) (would gladly bring him back to the LFS if
incompatible
though)

<Future troubles with allelopathy with this mix>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Ok, sorry for the long intro, but I wanted to make sure you had ALL
the info I could possibly give you.
Thank you for looking at my e-mail, I am in dire need of advice.
I discovered recently (4 days ago) that my snowflake moray had some
terrible wounds.
<Ah, yes... likely from scratches, stings from all the hard
invertebrates, cnidarians>
I don't see him that often as he usually hides under a large piece
of liverock so it is hard to say when they first presented. There is
one massive laceration midway down his back followed by two smaller
ones into his dorsal fin. All are evenly spaced about 1.5 inches
apart. The main wound has since caused the skin to turn white in a
band reaching around his body to his stomach on his right side. My
first thoughts were that he had gotten "stuck" in my Squamosa
clam... but the wounds were on his back... and the spacing isn't
right for the scutes of the clam. Secondary thoughts included that
he tried to burrow under a rock and caused the wounds himself (he is
quite a burrower), or that the new Rabbitfish "got" him with his
spines.
Last night I spotted my green brittle star climbing for the top of
the tank (unusual for him, he usually never moves from "his" rock)
after the halides had turned off and saw that he too had horrible
looking open wounds (you could see right through his body).
<Trouble... in this tank en toto>
The only *known* option I can see that could cause both wounds would
be the Rabbitfish.
<Mmm, no... much more likely the entire system is in mis-arrears>
I knew Rabbitfish stings were horribly painful, but I am unaware if
they cause flesh decay or recession. Could this be the case or do I
have some horrible parasite or something. It would seem odd that a
parasite would attack both an eel and an echinoderm though, yes?
<Agreed>
These injuries are truly terrible looking and I need to isolate the
cause and eliminate it ASAP. I can't stand seeing my pets in this
condition, I was sick to my stomach all night.
Thank you again,
Eric
<... read quickly on WWM re the Compatibility of each species/genus
listed above, separate these animals just as quickly... you need two
tanks for what you list, or one very large one (hundreds of
gallons). Bob Fenner> |

Re: Something truly Horrible is going on in my tank. Please
advise. 9/15/06
Thanks for the response Bob!
<Welcome Eric>
I pulled the snowflake out and put him into QT the other day.
<A good start>
He'll likely be going back to the LFS if/when he gets better. I'm
trying to move more toward a reef tank instead of focusing on
vertebrates and motile inverts...
and he is most likely going to get himself killed or kill other
things.
<Yes... very likely>
Unfortunately I had to euthanize the brittle star in the freezer.
<This is/was best I assure you>
His disk was nearly completely gone last night when I got home and
he wasn't moving at all.
I will remove the Condy as soon as I can get at him easily since he
has already decided to climb on top of the Galaxea and nearly died
from the stings.
<Yes... Oculinids are the big/gest "winners" in such encounters>
I added the skimmer (Aqua C Remora w./ Maxi-Jet 1200) about two
months ago.
(sorry, I copied the list of equipment from an earlier e-mail
because I was in a hurry and worried about my inhabitants. The
occupants list is 100% up to date though).
<I see>
Am I interpreting properly that the skimmer should *help* cut down
on the allelopathy issues by removing a good amount of the
contaminants?
<Yes, but not sufficient to "turn the tide here"... need more
room... chemical filtration, the use of live macro-algae (best in a
tied-in refugium...>
I use a good bit of carbon (about four cups worth in one filter, two
cups worth in the other).
<Wow! Of high quality? This is a bunch!>
Should I add PolyFilters to help remove contaminants as well? Do
they really DO anything?
<Yes and yes>
Upon more thoroughly reading the compatibility sections related to
these corals I have determined that the Green Finger Leather is the
most noxious,
<Correct>
but that, the Corallimorphs are right up there with it,
<Close seconds>
and that the Galaxea, polyps and the Zoa's are also very toxic...
<Bingo>
I've been looking around, is there a chart or a scale for this sort
of thing?
<I do wish there was. Not as far as I'm aware... Would be great
(hint, hint) if someone were to assemble one... sell as an
article...>
I'd like to have happy inhabitants, but I can't figure out who is
more toxic than who, who threatens who more, or who to remove from
the system.
<Ahh!>
Everything I read seems to suggest that they are all a danger to
each other.
<This is fairly accurate... there are only some general approaches
one can take... start with small specimens, less "stingy" ones
first, not add much more up to a point...>
Could you make some quick suggestions?
<Mmm, a boat load... they are part and parcel WWM>
One thing I noticed while reading through the FAQ's today is that
starting all corals as small colonies and allowing them to "grow up"
together can help dull chemical sensitivity issues.
<Yes, this is so>
None of my coral inhabitants are of significant size except for the
Galaxea (about 3 inch diameter) and there is easily 8 inches between
each specimen. Any chance they could grow up happy together?
<Always a chance, chances>
Thanks again. I'm going to continue reading now. I gotta' figure all
this out.
-Eric
<Thank you for your earnest, intelligent participation/sharing. Bob
Fenner>
