Re: Quarantine for fish shipments, Hermits.... Damsels breaking down,
comm. 12/9/15 Re: Injured Lemon Damsel? 6/30/10 heart attack, swim bladder problem? Damsel stressed to
death, env. 5/13/10 Re: Help with Sick Damsel Follow up questions.
5/1/2010 Saltwater yellow belly damsel rapid breathing,
4/20/10
Damsel Disease/Crypt/Ammonia Poisoning
5/14/2009 3 stripe damsel labored breathing and turning colors
01/22/09 Hi my name is Brandie. <"Oh Brandie...
you're a fine girl, what a good wife you would be! But my life, my
love, my lady... is the sea!" Sorry... I love that song.>
I'm new at this, I just started my salt water tank a few weeks ago.
I have read all throughout my book and online but can find no answers.
I have a 30 gallon tank and all I have in it is 2 blue and yellow
damsels and 1 three stripe damsel. <Poor choices for a 30g tank.
They will get big and mean and kill each other or die.> Today when I
got home I noticed my three stripe was belly up at the bottom of the
tank. It now has labored breathing, the white parts of its body are
turning gray and it is completely still but just jerking occasionally.
I am very paranoid and I check my water daily and it is fine so what
could this be? <What do you mean by "fine?" What all did
you check? How long has the tank been set up? What do you have for
filtration? I'm sorry, but I need a lot more information to help
you.> Is it a disease? Please help soon! <I suspect toxic shock
of some sort... but again, I need more info please. Best, Sara
M.> damsels - please help! Hlth., env. 10/14/08 Hello -
<Amber> I sent this e-mail to you 3 or so days ago and
haven't heard anything...I really need your help, please...I'm
really lost. <Mmm, haven't seen this> Here is the e-mail I
sent... "Let me first say that I am new to marine fish, and this
is my first try at setting up a saltwater tank. I completely cycled my
55 gallon tank 2-3 months ago, using the fish-less cycling method. I
have cycled many freshwater tanks using a similar method, so I am
familiar with the cycling process and what to look for during the
process. Once Ammonia and Nitrite levels were both back down to 0, I
figured it would be safe to add a few damsels. I took a water sample to
my LFS and they confirmed that my water was in great condition and it
would be fine to add some fish. I picked out 3 yellowtail damsels, and
after acclimatizing them for 1 hour, I added them to the tank. I did
not quarantine as they were the only living things in the tank at that
time - there was nothing for them to infect. Sadly, after approximately
a week, one of the damsels began showing "white lips" which I
usually would associate with columnaris. <Mmm, no... not this...>
I am not certain if there is a marine variety of this disease;
searching online has given me mixed results. <Can easily do so...
does to/for me all the time> I was told that damsels often get
"white lips" from crashing into rocks, fighting for
dominance, etc. so I kept an eye on it for the evening while I fed them
their mysis shrimp. All three ate normally. The next morning, the
damsel with the "white lips" was dead, and the other two were
showing the same symptoms. They died later that day. <Summat amiss
here... en toto> I did a water sample using my personal kit, and
came out with near ideal readings. <Bear in mind, this set of
results was for what you could, did test for... NOT all
possibilities> I took a sample to my LFS, and they confirmed the
readings. (Ammonia = 0, Nitrite = 0, Nitrate = 10, pH = 8.3, temp. =
76) I was advised by my LFS to allow the tank to set fish-less for a
week <Good advice> and raise the temperature slightly, which I
did. After a week and a half, I did yet another round of tests on my
water, and took a sample to the LFS for them to check. Again, nothing
other than ideal levels. They said I could try again if I wanted to, so
I chose 3 domino damsels <Mmm, this species... can't really be
crowded like this...> (their tank at the LFS was on a different
system than the tank of the yellowtails, since I suspected the fish
came to me with the disease and wanted to avoid buying fish from the
same system.) Again, I acclimatized the dominoes for a good hour, and
released them into the 55 gallon. They have been eating heartily (I am
feeding frozen/thawed mysis shrimps currently) and are exploring their
environment. Tonight, they have been with me for almost a week, and I
just noticed a small, lighter colored area on the largest domino's
upper lip. It is not by any means white, but it is lighter than the
rest of the domino's body color. It isn't as dramatic as the
white on the late yellowtails, in fact, the more I look at it, it seems
almost as if it is natural coloration. Perhaps I am just being overly
paranoid...Should I treat all 3 with malachite green, <? No> or
should I let them be? <Something else...> Their behavior is
great, and they are still eating heartily, though they seem to have
clamped their fins a bit (this might be because I've been worriedly
staring at them for almost an hour.) I don't want to lose them, but
I'm afraid that if I chase them around to medicate them, they may
succumb to a stress-induced infection." Thank you so much for your
time and advice, Amber <Do see your LFS re a product call
"PolyFilter"... place a pad of this in your filter/flow
path... I suspect you have some sort of toxicity issue here... The pad
may change color, give us clues. Bob Fenner> Velvet Damsel seems to float to the top. 5/10/08 I just bought a Velvet damsel the other day. He seemed healthy in the store, he swam around in his tiny area. The store kept him in a tiny box "tank" around probably 3x3x3 inches. <yikes> I then put him into my quarantine tank. He was fine all day yesterday. But this morning I looked at him and noticed he seems to be trying not to float to the top. He swims a little just to stay neutrally buoyant. But once he stops swimming he starts to float up. He wasn't floating yesterday, he just swam around. <Hmmm...possibly a swim bladder problem.> He looks completely healthy otherwise. The quarantine is a 10 gallon tank. The specific gravity is 1.016 (I read that its good to keep the salinity levels low in quarantine tanks, although it might be too low?). <The salinity of the quarantine tank should be the same as the main tank.> I haven't tested other parameters as of yet, but I'll have them by tonight, I work at a pet store, so I can test them when I go to work tonight. Is it possible that the specific gravity is too low, and that's why he keeps floating? Or might there be something more going on that I do not now of? <It's hard to say, but I would raise the salinity and see if that doesn't help.> The quarantine was only set up for about a week, and it was good the other day, all levels were normal. I scraped the bacteria from my main tank and added it to the filter to jumpstart the nitrogen cycle. <Ok, good luck, Sara M.>
Damsel Distress 4/25/08 Good morning Crew, I hope everyone is well. Let me start with my tank setup. 125 gal., 100 or so lbs. of live rock, PH 7.8 ( working on raising it ), KH over 300 ppm, ammonia and nitrites 0, nitrates 40. <Hmm, high> Not currently skimming. <I would> The livestock consists of 12 dwarf hermits, about 10 snails mostly Astrea, 1 small Snowflake eel, 1 Cubicus Boxfish juvenile, 1 small Spotted Grouper, 3 Damsels, ( 3 Stripe, Domino and Blue Devil ) a Long spined Urchin, and an orange Starfish. After sifting through FAQ's and Googling for a few hours I am still left with a question regarding my Blue Damsel. For the last 3 days, starting in the late afternoon, he begins to swim around the bottom of the tank looking like he can't get his bottom off the ground, and breathing hard. It looks like his back end has been weighted down while he's trying to swim. During the day he swims fine, the Grouper and the Damsels chasing each other through the rocks, and he comes to the top of the tank for morning feeding but come evening he can't or won't get off the ground very readily. Everyone seems to get along fine since they were all introduced in the same week and are all juveniles. They sleep together, and are only aggressive towards the eel, not each other. I observe the tank for hours each day and get up in the middle of the night just to see what's going on - just a bunch of sleeping for the fish. Is this normal behavior? <The inter-species aggression/territorial is, the butt-dragging, not> I have also noticed the Domino's black color fading to a greyish brown starting from the tail yesterday and today, any suggestions on what might be going on? Everyone is lively and eating voraciously. Thanks for being my complete go to Crew! <I suspect these Damselfishes were poorly collected, handled... not decompressed properly, held, shipped in the usual deplorable ways... In the present setting it is likely they will perish from these influences than be consumed by the growing grouper. Bob Fenner>
What to do with a sick damselfish in a small tank that's cycling 01/11/2008 Hi, <<Hello, Andrew here>> My new 65l tank is in the third week of its cycle (unfortunately, not having researched this hobby adequately, I was persuaded that the damselfish method would be ok -reading your site I realize this is not really the case). <<Glad to see this is realised>> I have 2 blue damsels and 1 blue/yellow damsel. The blue/yellow was never the most vigorous but for a week or so he has been floating around at the surface and not really eating, his eyes are cloudy and quite suddenly white areas have developed around his gills and head. I'm pretty concerned and wonder how to treat him at this stage of tank cycling - the other 2 fish are very strong and eat well. If I was to hospitalize this fish in a separate tank what water should I use? Can I buy special ready prepared water? <<Its not just water you need, you will need a cycled tank to move the poorly fish too. You best course of action is to catch the fish, and take them back to where you brought them from. Then add a raw (uncooked) shrimp or prawn as your ammonia source, instead of the fish, and cycle correctly. This way you don't harm the fish any more than they have been, and you wont be stuck with semi aggressive fish after the cycle>> What would I do with the other fish if this is a parasitic infestation - would I need to stick them in yet another tank? <<As above, you need a cycled aquarium to move them too, which you don't have. Take note from my comment above regarding taking the fish back to a store and get some store credit for them>> Any help would be appreciated, thanks, Sean. <<Thanks for the questions, A Nixon>> Damsel bent, and holy fatness!! 10/1/07 hi crew, if it isn't one tank it's another! I have 3 black and white stripped damsels (Humbug aruanus). I've had them about 2 weeks. 1 of them, after my water change yesterday bent like a banana and became really fat! <Unusual> Looks like he (or she) swallowed a marble. The only thing I can find with that as a symptom is fish TB, and skinny is a symptom there, not fat. I thought that only affected freshwater fish. Then I thought some sort of internal parasite, but no luck on finding anything on that with these symptoms. There are no other symptoms. Scales appear fine, all intact, no spots or dots or holes. Tail and fins are intact. Color is great. Just all bent in the spine, fat and swimming sideways, like swirling. sometimes does a summersault. <Bad> He'll rest on a plant for a while. I watched the tank for a long time, And the other damsels and the clownfish appear to be worried(?). Seriously. They are hanging close to him and if he hides in a plant someone will swim and hover by him or swim between him and the glass. Almost an encouraging/comforting type thing, <Are social animals, both species> he stays in the open water half of the time, no one is picking on him or anything. I've tried to chase him with the net to move him to the nursery tank, Then he swims almost normal across the tank and hides very quickly, but still bent. His breathing doesn't seem to be erratic, but the poor thing is working awful hard to stay upright. He's only a 4 dollar fish so I won't be devastated if he doesn't make it, but if it's something contagious, I need to know what it might be, if it'll spread to my other critters and how to treat it. All other tank mates appear to be normal. Water parameters, 55 gal. Temp. 78 Salinity 1.024 Nitrate 0 Nitrite 0 PH 8.4 Ammonia 0 Calcium 480 <A bit high... are you boosting? How?> Phosphate 0 Carb. Hardness 8-9 (should this be higher?) I don't try to raise it if it's in the normal range. Alk 180 Thank you once again, I'm so glad you here for all of us. Rochelle <Perhaps a gut blockage... From? All one can do is wait, hope here. Bob Fenner> Damselfish Troubles 9/5/07 I recently bought two yellow tailed damselfish. For the first week or so they did great, then yesterday I got out of bed and one was dead. I thought it was just his time, <What would lead you to believe this?> but then I looked at his buddy and I saw that half of his lips were gone and there was some white looking stuff going towards his gills. I do remember when I bought them the one looked like he had bubbles on his lips, but I thought it was just from me putting them in the tank. <Unlikely> Hind site, could it have been a disease of some sort? <Perhaps> I am still new to the saltwater game. I have a 55 gallon tank with 57 pounds of live rock, canister filter, skimmer, and a cleaning crew. Tired of dead fish please help. Thank you <Too much to cover here, I recommend going through our articles in the marine section, especially the ones dealing with Quarantine and disease.> <Chris> Sick damsel, senescence 8/8/07 Hi, I've been reading symptoms of other people's fish and haven't yet found the same combination as my fish. He stopped eating normally a couple weeks ago, but it looked like he was eating stuff off the bottom of the tank, so we didn't think much of it. Then I noticed him sort of "bobbing" up and down from the floor of the tank to the surface and back down. He wasn't swimming, just floating up and down which he's never done before. I started getting a little worried at that point. Then, two days ago, my husband witnessed the fish spinning in circles and spiraling up to the surface and down to the bottom. He feared the end was near. That day, the fish was very lethargic and would just float around, occasionally bumping into things. Yesterday, the fish was still hanging in there, but I witnessed him do the spiral thing again - which is very frightening to watch since he looked completely out of control. After that, the fish managed to get under a rock and hide. At that point, my husband moved the fish into another tank. He's been in that tank since last night. One of his eyes is extremely dark and sunken in. The other eye looks like the classic pop eye. And it appears he's breathing rapidly. I haven't noticed anything unusual with is skin or fins. Any advice? Or is it too late for him? <Yes, maybe...> My husband tells me the fish is about 10 years old and suspects it's just old age. <Possibly> Oh, my husband did a water test of the original tank and everything was normal, although I don't know what the results were a few weeks ago when the symptoms started. Thanks, Karen <Please read here: http://www.wetwebmedia.com/damseldisfaqs.htm and the linked files above. I suspect the "old age" part here myself. Bob Fenner>
Please tell me what is wrong with my tank! Territorial issues likely First things first - an overview of my setup:I have 2 10G tanks attached to a home built sump in a 10G that actually holds about 7G for a total water volume of 27G. My first tank is setup to be a reef tank with 76W of compact florescent lighting (26W full spectrum, 10W 6000K, 5W 10,000?K daylight and 5W Actinic 03 blue). Approx. 100GPH sump circulation W/ a 200GPH recalculating pump. 10 lb live rock 10lb live sand 5 lb crushed coral over a 1/2" plenum. This tank has always had a peppermint shrimp that has molted 3 times - and has always done awesome. There are 2 small corals but I have not have them for long enough to gage how they are doing. There are several things growing happily off the live rock and a small unknown hitchhiking anemone. The other tank has 38W of full spectrum lighting. Approx. 100GPH sump circulation W/ a 145GPH recirculation pump. 3 lbs of live rock and 3 pounds of porous rock with 8 lbs of crushed coral. There is a peppermint shrimp and an emerald crab that has been in here since the start. My sump has a Fission nano skimmer that I have fiddled with enough to make work well, a 100W heater, a pre-filter pad that is rinsed weekly. I put 4"of sand in my sump along with several clumps of macro algae, and 4 mangrove plants growing quite happily under 80W of plant grow florescent. I also have a DIY coil denitrator. My tank lights are on 12 Hrs/day and my sump runs opposite 18 hr/day. <All sounds/reads good/spiffy thus far> Maintenance: I top off my tank with tap water - which I know is not the best of practices - but I use a tap water filter and I add a de-chlorinator and let it sit in a jug with a bubbler for a few days before using. I add the Kent marine SuperBuffer for PH and KH control along with iodine for my shrimp and Iron for coralline algae growth - again I know it is not best practices to add supplements blindly but I have yet to obtain test kits. I do a 10% water change bi-monthly. I feed my inhabitant's 1/day 6 days a week a varied diet including phytoplankton. Test results: PH - 8.6 - added slightly more buffer and will retest in the morning. Ammonia - 0.1 mg/l - but I just had a fish die and it was probably in there for about 12 hrs before I found it. Nitrite - 0 mg/l Nitrate - 0 mg/l KH 240 PPM Temp: 81 and quite stable I have a bit of a hair algae problem as well, but I have not tested my tap water for phosphates so that could be my problem. So my problem is that I have to date lost 6 fish. A pair of false Percula clowns, a lawnmower blenny, <Need more room...> a Royal Gramma, a Domino Damsel, <D'oh! Am glad I'm not in such a tiny volume with this bully!> and a yellow goby over 2 months. I currently have a surviving damsel but it has only been here for a week. I would think that if there is something horribly wrong with my water that my shrimp would have died/not have molted. <The animals you list all need more space... the Goby, live Acropora...> But at this point I have no idea what to do. please let me know if I have forgot anything relevant, I have probably included far more information than you need, but I hate it when people say "oh it is the typical setup and my test results are all ok" :). Thanks for your help. James Laster <Could be quite a few "things" at play here James... most likely though, all added to with territorial issues from the mixed stock... Perhaps an imbalance of calcium/magnesium for the Lysmata... Please do read re the Systems FAQs for all the species you list above; on WWM. Bob Fenner>Re: Please tell me what is wrong with my tank! Territorial issues likely 5/29/07 I am aware that most of these do not play well together, <Mmm, actually most all those listed "do play well together"... just not in such a small "playground"> but they were not in the tanks together, each was purchased to replace the last. <Still too small a volume... even by themselves...> There have never been more than 1 fish in a tank at the same time, any ideas now? or am I just SOL? <More like FOL, Fish Out of Luck. Look, read re livestock selection for small systems... on WWM. Bob Fenner> Sudden death of a Damsel 4/21/07 Hi crew, <Kwon> Thanks
for all the helpful info you've posted on your site. Here's my
situation: I have a 55 gal fish only with LR. I have one damsel and one
trigger (small, 2-3 inch)...and yes, a bigger tank is in the works.
Today, I fed them with frozen trigger formula like I always do. I went
out for about 4 hours, when I return, I found my damsel dead. I
remember it was eating like a pig, as always, before I left the house.
So I dug him up and did not notice any physical damage. All I've
notice was that the gill portion of his body looks a little bulged.
What do you think might have killed him in such short amount of time?
<Mmm, impossible to say... perhaps a rupture in its blood/vascular
system... a "heart attack"... Fear of the trigger
tankmate...?> I see him every day and there were no symptoms of any
thing wrong. My trigger seems to be fine for now. He is sleeping in the
rocks. Should I perform a water change? <I would test the water for
what you have kits for...> Please advise. Thanks. Kwon. <Do know
that such rapid deaths in Damsels are not uncommon... especially when
small, good numbers of these fishes "do just die" w/o
apparent reason at times. Bob Fenner> Only Damsel fishes with ich? 4/16/07 Hey Crew, <Rachael> I have read your website for hours upon end and found many answers to many questions. <Me too> I am always appreciative of good info. <We do have quite a bit in common...> I have a 20 gal nano reef... the tank has been great for 2 mths. Today, I added two new pieces of coral, and within an hour, I had a blotchy and lethargic YT damsel and a white spotted clownfish. <Mmm... likely related events> The only other fish I have is a PJ Cardinal, and he shows no signs. <Less affected... thus far> I am setting up a bare bottom HT today (read the WWM specs) and going to dose with what I am sure will stain the tank, and stains will be permanent (gotta give and take). So here is the question... why is the ich so sudden on only the damsel family fishes? <More "stressed" in this case... perhaps more easily afflicted by whatever the cnidarians introduced are releasing... I would go so far as to speculate that Pomacentrids are more sensitive to such from their close/r association with Anthozoans in the wild...> Also, should I dose all fish in the HT, or just the two symptomatic fishes? <Mmm, all fishes must be treated... and your system left fallow (fish-host/less) for a period of time...) as your system itself has whatever this is (likely some protozoan...> As a side note, I am also going to try the Kordon organic ich treatment to find out if it has any credibility. <Worth a go. Bob Fenner> Thanx!! Rachael Blue Green Chromis Dying 1/8/07 Bob, <Leslie here this fine evening> Searched FAQs. Found a few regarding the red spots (look like internal bleeding) on Chromis. We turbo started our tank and bought 2 false clowns and 4 b/g Chromis. One of the Chromis got a red spot - and very quickly - one would die another would get it - until it wiped out all four of them. Clowns are still alive and doing great and a blenny too. This was 5 weeks ago. We test the water weekly at the store - everything is great. 90 Gal Tank with about 14 lbs of live rock - with a refugium. We just bought another 6 b/g Chromis from another store Friday night. Same thing - one died Saturday - one is at the door of death - and I can't get to him Sunday - probably dead today - three of them I scooped out - not taking any chances - rather loose the money - than loose other fish. One seems to be healthy no spots and swims with the clowns. Whatever it is - it only seems to bother the b/g Chromis. Clowns are still fine and our lawnmower blenny is still fine. As well as several invertebrates (snails, crabs, shrimp). Do I need to worry about treating my water to avoid infection on other fish. <It's not really advisable to treat the main tank. Sick fish are best treated in a hospital or quarantine tank.> Or where these fish already doomed somehow? <Not necessarily. However I would keep a close eye on them.> Any input is highly appreciated! Brian <It is always a good idea to do some extra water changes when there has been a problem like this in a tank….. "dilution is the solution to pollution" as it has been put in quite a few other articles. This goes for pathogens as well. You could place UV on the tank for a while. One of your best ways to avoid problems like this in the future is to quarantine all new additions for a minimum of 4 to 6 weeks. to avoid problems like this.

for helping me with this situation. I purchased two yellow tale
<tail> blue Damsels and put them through 4 weeks QT.
<Good!> The day of the move to the main tank to minimize stress I
did not turn the lights on in the QT tank and had to chase them a
little bit. The next morning when the lights came on in the display
tank I noticed that one of the Damsels has a white line that runs from
behind his eye to the bottom of his chin. <Mmm, just "night
time" coloration?> I also notice that it appears to be peeling
off. I thought that it might be an injury but now that it is peeling I
am not so sure. Other than that he is perfect. Great color, active,
breathing normal, and eating fine. Could this just be an injury from
the move? <Yes...> Should I try and get him out and put into a QT
tank? Any advice is appreciated. Thanks again for all you do, <I do
think this line is/was the result of a physical trauma... and that it
will likely "heal over" in a few days. I would not further
stress the one fish, or the system by trying to remove it. Bob
Fenner> "Hole" in My Damsel - 10/23/06 I have searched about and found the HTH description. I have 2 damsels in a 30 gallon one is a blue and the other is a blue/yellow. When I first got them the yellow had a yellow tail and a yellow spot right before his tail. I thought nothing of this but today my daughter pointed out "Hey daddy that fish has a hole in it". <<...!>> To my surprise she was right; the yellow spot is now a "hole" clean-through. <<Perhaps not a "spot" at all then. Possibly was a parasite, or some other physical trauma that developed in to a bacterial infection. If the hole continues to grow your best option may be to euthanize this fish>> This fish has always been on the docile side as compared to the other. <<As would be expected. Though not a "gentle" fish, the yellow-tail blue damsel is on of the more peaceful of the damsel species>> Sadly these fish have been used to cycle a new tank. <<Mmm, not necessary...can be done without subjecting fishes to this treatment>> Tough little buggers. <<Indeed...but still no excuse>> Could this be a disease or just because of the stress I had put them though? <<Hard to say...but whatever the cause it will certainly have been compounded by the stress of a new/cycling system>> Any help would be great. <<Regards, EricR>> I shot the sheriff, no, I killed a damsel? 9/26/06 Wow, what did I do? <Is this that Blondie pop singer writing me again? My wife doesn't approve> Ok, so I've been keeping a fish/invert tank for 4yrs and am setting up another predator tank. My cycling fish that will fit in well, is (was) a jeweled damsel. <Not a good idea... am a fan of fish-less cycling> He was about 2.5" long. Anyhow, I have some scattered liverock in a 20gallon quarantine tank to which he has been residing. The tank has been running for months and previously housed my Royal Dottyback for 2 months. I do water changes about 30% twice a month and the new water is directly from what is soon to become my reef tank. I have no new liverock in my quarantine. My pH 8.2 No sign of nitrates, nitrites, ammonia. Salinity holds steady at around 1.024 (1.0024?) <The former> and the water temp steady at about 26oc. The damsel was aggressively feeding up until two days ago. He was dead and stuck to the powerhead (a small MaxiJet 900) yesterday. The day before he was alive and hiding in a small cave of the liverock. The day before, he was hanging out at the top of the water level waiting for me to feed him... to which he aggressively gobbled everything down. I've been feeding a mixture of flake, krill, shrimp, etc. Alternating every few days. He looked pretty healthy. There's nothing else in the tank with him and there's no marks on his body. He lasted 4 weeks and his behaviour change leading up to his death was over the course of maybe 30 hours. I did an immediate water test when I discovered him. The only thing I can remotely even think of is that over the past 10 days, a small Cyano colony on my live rock turned from a fuzzy purple to a dark green/grey. <Mmm, this could "do it"> It looked kinda sickly. Water parameters stayed excellent. Any thoughts? <Yes. Hopefully this fish hasn't infested the system with parasites. BobF> Regards, Dave Brynlund Blue Damsel - Danger? 5/12/06 Dear WWM Crew - Hello from Central Florida.... <Hello from rainy Chicago> We have searched for an answer to our dilemma on all sites we could find with FAQ's on Blue Damsels to no avail.... So, our query is this -- our Blue Damsel has suddenly sprouted a 'growth', for lack of a better description, on his back. It looks like a whitehead pimple. Is this dangerous? He eats and swims quite normally....hmmm....can you help? <Hard to say without a picture, but I would guess Lymphocystis, Google this and see if it fits.> Mark and Tom of Lakeland, FL. <Chris> Domino damsel/s sick - 03/12/2006 Hello, I was hoping you
could help me. I have never had good luck with domino damsel fish for
some reason and this one is no exception. <Unusual> I bought him
about 3 weeks ago and he was doing fine but now I noticed his color is
fading and he is breathing rapidly with reddening near his gills. This
has happened to my previous dominos last year when I was starting my
reef tank. Now I have a wonderful established reef with near perfect
water, 0 nitrate, 0 ammonia, ph 8.3 checked weekly. Everyone else is
doing fine my rusty angel, blue and zebra damsel, and 2 small Chromis
are thriving. Is there something dominos specifically need or do I just
have bad luck with them? <Not luck> What would you recommend as a
medicine to help his problem? Are there any non-copper medicines I can
use or than won't damage the inverts? Any help would be great. tank

Fenner> Pot bellied Blue damsel - 2/28/2006 Hi, Thank you for all the information I've absorbed over the past couple years. <Ah, good to read that you have gained by our efforts> I have 6 tanks all doing well, all fish doing well. (Short of my own procrastination of water changes , 20% change sort of weekly) LOL. I do have one fish that has sent me to your site on several occasions with no answer to be found. This blue damsel has looked VERY pregnant several times now. Once again he's all bloated looking but seems just fine. When I look on your site ...searching with: "blue damsel looks pregnant" I get a long list of letters/responses having nothing to do with my search I hunt down the list and find what I kinda need deep in the list maybe I just search improperly <Do substitute "bloated" for "pregnant" and look at the cached versions (for highlighted key terms)> All I've been able to find is that it could be a parasite or gut blockage <This/these are most likely... along with "mis-feeding"... too much dried food at a time> this phenomenon has happened before and gone away so I'm not worried just frustrated about not knowing the cause of this "bulging belly" what do you think? David Conway <Mmm, another possibility... just that this fish is "anxious" due to living in more stressful setting than the wild (in large numbers with arborose coral to dip into)... and overfeeding due to this. Bob Fenner> Gold tail damsels changing colors - 02/25/06 I am cycling a new 110 gallon saltwater tank. <There are other, better ways w/o fish present> I notice a couple of days ago that my one gold tail damsel was getting darker while the other stayed the same color. I test my water to see if there are any changes. Everything is cycling as normal. PH @ 8.2, NIT @ 10, and AMMO @ 0.1 The darker on eats normally does seem sick. But now I notice that the damsel that was normal colored is slow becoming darker. I've looked all over to see if they change color as they mature. I don't think they should. Could they have an internal parasite that could cause a color change? Heather from Wahiawa, HI <... could, but much more likely just stress-coloration from being present in a toxic environment. Please read here: http://wetwebmedia.com/estbiofiltmar.htm and the linked files above. A hu'i hou! Bob Fenner> Pink sore on green Chromis... env. dis. 2/17/06 Hi all <John> I have a 250 litre (c.60 gallon) tank with a 40 litre (c.10 gallon) sump that I've been running for about a year. Last addition was over four months ago. Contains: 2 tangs <Too small a volume for....> 4 green Chromis 1 Banggai cardinal 1 orange-spotted sleeper goby 1 pygmy angel 1 tomato clown 2 cleaner shrimp 'big pile' of rock, mushroom leather, small bubble, clove polyp, anemone (aka clown sleeping bag) ... 2 romantic starfish and about a zillion starfish babies... and one or two very shy red-clawed hermits and some slug-like hitchhikers <Good descriptors> Equipment: UV, skimmer, refugium in sump, 2 powerheads in tank + return pump, metal halide 10 hr/day, night light in sump. Has been going really well, zero mortality since a heat wave last July, but this evening my daughter spotted a 2-3mm raised pink sore on the smallest Chromis. Behaviour (the fish, not the daughter) is normal, so far. He fed fine this evening. Parameters a little off as I've been topping up with RO but not changing very frequently: NH3 = 0 NO2 = 0.3 <Mmm...> NO3 = 100 (yikes!) <Yeeikes!> pH 7.8 <A bit low> SG 1.025 (more RO needed!) <And buffer, and water changes...> Any idea what this sore might be? <Environmental and social stress> I have no QT/hospital tank - what could I do in the main tank? <Fix your water quality> What is the size and time lag of water changes I should do to get that nitrate down to acceptable levels? <Posted... and not the entire approach I would take...> Thanks for your time and help! JC <Do start those water changes, reading re Nitrate control/reduction. Bob Fenner> Dead Four-Stripe Damsel -
2/4/2006 Hello, crew! I love your website and have gained much
information about damsels there. But now, I feel like I'm a bad
mommy. I found my four-stripe damsel at the bottom of the tank this
morning. Here's the info: January 14 I purchased two damsels: 1
blue damsel, 1 four-stripe damsel. I had just set up a 55-gal tank with
live rock and sand. <Not good to place fish life in uncycled
systems> I waited a week after set up before purchasing the damsels.
<Not long enough> The first week the four-stripe would nip at the
blue if she came near him, swim to the top for food and exhibited a lot
of personality. The second week I noticed the four-stripe had stopped
nipping at her. Then, I saw a white string coming out of him but I
thought he was, you know, using the bathroom. A few days later I
noticed a brown coloration on the wings on his back. Last night I saw
another white string coming out of him. I have been feeding them flake
food in the morning and frozen brine shrimp with flake food in the
evening. I hadn't seen him eat for a few days and he was keeping
close to a plastic decoration I have in the tank, but articles I read
about damsels said the four-stripe doesn't eat much and sometimes
they do stay in one part of the tank. I also noticed, two days ago,
what looked like pieces of white flake stuck to one of his wings (or
are they called fins?). <Yikes... I hope you have not introduced a
parasite into the system... no quarantine...> I do have a water test
kit and here are the levels, which have been consistent: Water Temp
76-78; pH 8.2; Ammonia 0; Nitrite 0; Nitrate 40 or less. I purchased
the saltwater from an aquarium store -- took two trips. <I'll
bet... is heavy to lug around> My question is: what could I have
done to prevent his death? <... not placed into non-ready
environment, dipped/quarantined...> My blue damsel seems quite
healthy and hearty (or should I say greedy!) but I want to make sure
she doesn't get whatever he had. By the way, a few days ago I added
romaine lettuce (small amount) because I read they like that. I was
hoping it would tweak his appetite. Brenda Truitt <Mmm, very likely
the damsel/s were "challenged" health-wise before your
purchase (common), and the added stress just worked itself out here...
But I do encourage you to read re quarantine, foods/feeding/nutrition
of marines... and of course investigate species, groups ahead of
purchasing. Cheers, Bob Fenner> Damsel help 1/18/06 I have two neon blue damsels recently one started to get a bubble around its eye then two days later the other eye. It's also losing its scales and seem not to be eating is this a disease or something else. And if it is a disease should I take him out of the tank so not to contaminate the other fish? <... these are signs of poor/unsuitable water quality... Perhaps "things" for which there is/are no ready measures (test kits...). I would "do" the usual water changes, add chemical filtrants to the water flow, supplement foods... or move them to another system, stat! Bob Fenner> Damsel fish respiration/breathing rate 1/11/06 Hi, <Hello Chris> I have 2 humbug damsel with what I think looks like high respiration. I know lion fish normal respiration is 30 breaths per minute, could you please tell me what the normal respiration for a damsel fish is per minute, thank you <The humbug is rather active and what you are seeing isn't abnormal. I really don't know what the respiration rate is, never checked. Please do not ask what the blood pressure might be:):) <James (Salty Dog)> Chris Sick damsel 9/19.5/05 My blue damsel has big internal lumps on both sides of his body that have distended him outwards and are whitish. They look like they're about to penetrate the skin and he gasps. He's still active and eats well. I've read about the Epsom salts cure for intestinal blockage. I have 2 other fish doing well in my 10 gal. as well as a hermit crab and a new bubble anemone but the damsel has been with me about 3 yrs. and is by far the oldster. I have no idea about ammonia levels, nitrites, etc. I change the tank infrequently and feed fish pellets every 3 to 5 days. I've had small marine tanks for about 11 yrs. and do well with them generally. Thanks for your help. Geralin <You've been pretty lucky as I see it. Water changes infrequently, no idea of water parameters, a bubble anemone in a 10 gallon tank?, a steady diet of fish pellets (not a good diet), and, as far as the damsel, he is getting old fast with all the above conditions. James (Salty Dog)> Damsel in distress, Dascyllus are social animals 08/08/2005 Hi, <Hello there> I purchased a four stripe damsel five to six months ago and have had continuous problems with it ever since. When I placed it in quarantine and it always preferred hiding behind the heater or other equipment rather than the PVC pipes or the artificial branch coral I placed in there. <... Dascyllus are social species... live in groups> She has also always been a very scared fish, and always hides except at feeding time. About three days after I got the fish in quarantine dark areas started forming on the white stripes just behind the gill plates and the last white stripe on the tail. the fish has been this way ever since. By the way the fish did lose an eye while in quarantine from injury most likely while darting to a hiding place when I entered the room. I kept the fish in quarantine for an extra two weeks and administered a copper treatment because she just was not acting right. <Starting to sound like the U.S. military's confinement of folks...> The copper treatment seemed to work somewhat the dark spots became more vague, but did not disappear. <... poisoning> However, she was still a very scared fish. After a month in quarantine I moved her into a 46 gallon tank (where she still is) with live rock and numerous hiding places but she still prefers to hide in the equipment at the top of the tank except at night when she goes down to hide in the rocks. The dark areas are still present and seem to grow in darkness when stressed (during water changes and when I clean the glass). There are no outward signs or parasites, but I do sometimes see her scratching on rocks. She is the only fish in the tank. The water quality should be excellent (I use RO/distilled water) and all parameters are good and consistent. She eats and seems to be a very greedy fish and is not shy around feeding time. So my real question is what could cause all these symptoms and this extreme fear of people and movement. The best answer I can come up with is stress, but I can not find the cause. Please give me your opinion. Also would it be safe to add another fish in this tank with her in this condition. Thanks for the great service, Jed <Thank you for writing to well, thoroughly... to reiterate, the one simple fact that you apparently are unaware of is the need for others of their own kind... Take a look at Dascyllus species pix in the wild... they are always in close association with others of their own kind. Bob Fenner> Sick Domino Damsel 7/22/05 Hi, We have a 92 gallon bowed corner tank. I'm not sure of the brand, but, we have a underground 30 gallon wet/dry filter. Also included is a rainbow lifeguard 25 watt UV sterilizer, as well as a protein skimmer. <Sounds good> We perform weekly water changes and check the levels every 3-4 weeks. Last tests performed about a week ago and water quality was perfect. <Perfect being?> Anyway, my problem is we have a large domino damsel; just tonight we realized that his left eye is huge! He looks and acts completely healthy, and the eye is not cloudy or covered by a film. I tried to take a picture to show to you but, the little guy just wouldn't stay still for a clear shot. Is this maybe the beginning of a Popeye infection, or something else? I know this might seem like a redundant question but since it does not look exactly like Popeye I'm not sure how to treat him. Thanks again, you guys are always quick and informative. <Observe him for a while to see if it gets any worse or better. If it starts getting worse, move to a quarantine tank and medicate for Popeye. If not, then I wouldn't worry about it> -Heather <M. Maddox> Saltwater Aquarium -- Damsels Dying :( Hi, I used to have several yellow tail damsels and 3 stripe damsels...all small. The tank also has several black mollies. For a while the damsels were doing great....then suddenly one died and within a matter of days, all the others died. After testing the water, I saw that everything was normal -- salinity, ammonia etc. I noticed that all the fishes died the same way -- they would get lethargic and hardly swim until they eventually just gave up. I could not see any visible signs of disease or anything and the mollies remain healthy. We did a 100% water change and then we tried again with the damsels, this time we only put in 2. Again, they all died in the same manner. I also noticed that the mollies were nibbling on the damsels. Should we remove the mollies from the tank all together? Please help!! <The mollies are not likely a real problem here... they're just hardier re whatever the root cause of the real difficulty is... probably water quality related... I would place a pad of Polyfilter in your filter flow path and check for resultant color for clues here... Possibly a bit of metal has gotten into your tank? Maybe a clamp... a misplaced decor item? Bob Fenner> Damsel Illness WWM crew, Sorry to write again, but the problem has changed. I did as you said and purchased a product to raise the pH and used it with the water change. The corals now appear much better, especially the mushroom. <Good to hear!> However, my striped damsel now appears to be under a lot of stress. He seems to be gasping for air, his respiration very quick. He also won't eat and is usually ravenous. <Under stress indeed.> I have two hang on filters running to change water flow for the corals, and one has venturi air action (I think that's what it's called). <Could it be a skimmer? :-/ > These have been up working together for months with no problem. He appeared stressed before I added anything but now is much worse. <Then his getting worse was likely brought on by the additional stress of the rapid environmental changes, even if they were for the better. The fact that he looked bad before the changes is not good.> I don't know what could be wrong? The mushroom was the first to be unhappy; could he be poisoning the tank? <I doubt it. I think the fish was already in bad shape, as you indicated earlier. I think the stress of changing conditions opened the door to illness.> Damsel blues Follow-up Okay, here is some more info that you asked about. Please see below. Hope you can help! <I'll do my best! Okay first thing I see is that you have GOT to get that temp. down. Is the heater set too high? Can you put a fan across the top of the water? Perhaps some more surface current? At this point what I would do is take out the carbon cause that is really messing stuff up. Yes definitely replace it with sponges. I'd do a 20 percent water change and then let the levels start over again. It should be fairly quick because a lot of the bacteria is in there. Next you need to get your salt up and I would suggest getting a hydrometer that is more accurate or getting a reading from the local pet store. I cannot imagine it going down that quickly. Its hard to imagine that you have nitrate readings already but this is okay, we can work you through it and it should help the cycle go a bit more quickly. The reason I'm suggesting the water change is that your damsel does appear to be having a hard time with it and I personally don't like the idea of having to lose animals during a cycle. If you slow it down you should be able to sustain your damsel and continue on with the cycle. Let me know how this works for you and we will go on from here. Good luck and don't worry you are GREAT parents.> Damsel sickness or health? Hi, I have two yellowtail damsels and one of them has developed a white growth on his mouth right on the lip it looks like. the fish has no other signs of problem and is eating and swimming great. Today I prepared and administered a freshwater dip for him but I'm not sure if I helped or not, the white growth is still there. Thanks for any help <Sounds like a "secondary" infection (microbial) from a physical injury (a bump in the night)... will hopefully heal with time. No real medicine to administer that is worth the stress of application, netting the specimen. Bob Fenner> Domino damselfish is turning blue on the
fins....acts like blind Hello...my domino damsel is 1 year old. he
has lost an appetite but, no thinness is shown. He swims really slowly,
and up against the glass, if you put your finger there he acts as if he
can't see it. there is no cloudiness in his eyes. but the edges of
his fins are turning blue. and the spot on his forehead is blue
completely. <Mmm, well, the blue coloring may be nothing to worry
about, but the other good observations you offer do worry me. What have
you been feeding your fishes? What sort of water quality test gear do
you have/use? What can you tell us about your set-up... the filters et
al.?> HE doesn't mind the other 4 fish he'll just swim into
them sometimes and they won't even go after him. he acts like he is
blind sometimes but there is nothing wrong with his eyes that I can
see. All my test are exact, I even had a local fish store check them
for me. <Good> My mom wanted to see if he could respond to
anything.. so she took the fish net and put it towards him he swam
away, but so slowly my 3 year old brother could have caught him.
Nothing seems to bother him. and he will casually bump into stuff but
then slowly turn around. He tried to swim through the plastic plants,
as soon as his top fin bump it he just turned around like he
couldn't get through.*****please tell me what is wrong*** I've
never lost a fish ever in over a year. And I don't plan to start.
Sorry but I'm new to this. I started last Christmas. And the pet
store I go to seems to be doing really well for it is an all saltwater
fish store. He tells me to keep my salinity low to prevent parasites.
1.010. is that too low all my fish seem to be use to it. ---Erica age
13 <I would not necessarily lower the spg here... but would
definitely try changing out a good part of the water (25% or so) while
gravel vacuuming, and look into adding a vitamin mix to the food you
offer. Often blindness is a result of a lack of nutrition. Bob Fenner,
much older> Damselfish with white spots I have had the Atlantic Jewel for 2 weeks. Just this evening (November 17, 2004) I have noticed on both sides of the fish large white areas, somewhat circular, about 1/2 inch in diameter. They are about in the center below the midline. The tank is a mini reef, so I'm hesitant to medicate. How do I start diagnosing what is wrong? << Wow that is tough. If he is behaving normally and eating then I'm not sure I would do anything. Although adding garlic to the food is a great idea. >> > I have a 58 gallon tank with 40 lbs live rock, several snails, hermits, > shrimp, a pick tipped anemone, large feather duster and a coral.

Scott F. here today!> I just set up a Quarantine tank after a bad case of Ich. I will quarantine all new arrivals. <Awesome! Another quarantine convert!> But my question is: I have only two fish left. A Black and white Percula Clown and a Blue Green Chromis. I was able to catch the Clownfish and put him the hospital tank, but I can not for the life of me catch the Chromis. (he never shows any signs of Ich looks and eats just fine) Is it possible to let the tank go fallow with just one fish in the tank. I don't think I will be able to catch him. Any suggestions would be greatly appreciated. <Well, you asked...Really, a "fallow" tank means just that- fallow! No fish at all. This is the only way to carry out the process of interrupting the life cycle of the causative protozoa. I'd use any means possible to contain and capture this guy. Often times, fish like Chromis can be more easily captured at night, after the lights are out. You simply shine a flashlight on them, and use whatever fancy netting technique that you've developed to capture them. The only other option is to take advantage of their natural tendency to head into rocks when you try to net 'em. You simply remove the rock that the fish is hiding in, and place it in your treatment tank. Unfortunately, it's easier than it sounds...But definitely worth a try! Good luck! Regards, Scott F.> A damsel problem In my marine biology class, we recently got 4 blue damsels, 1 yellow tailed damsel, and 2 4-striped damsels in. They were distributed blue blues to each tank, the yellow in one, and the striped in the other. Within a few days one blue damsel in each tank got the "lockjaw" that I have been investigating. They were each in separate environments for about 2 to 5 days, so I don't think it has to do with the environment, and it hadn't injured itself on anything. Both fish had died by the next day. We dissected one and nothing was stuck inside to prevent the mouth from closing. Today another blue fish has this same lockjaw, and we don't know what to do to cure it, if there is a cure. So unfortunately we assume it will be dead in the morning. Could you email me back with what you think the problem is and the solution, if there is one. Thank You -Paul Hooper <Mmmm, don't know of this ailment "lock jaw" in Pomacentrids. Some do die shortly after arrival (all are wild-collected) with their mouths "stuck open"... perhaps a manifestation of these specimens inability to generate sufficient oxygen, or loss of osmotic integrity... consequent to poor, rough collection, shipping trauma. Fishes have very high (relative to terrestrial tetrapods) hematocrits (packed cell volumes) and live in a world/environment much less oxygen concentrated (at most about 7,8 ppm of O2)... and can have real troubles if the availability of oxygen drops, other influences to its uptake occur (e.g. drops in pH, elevated ammonia in shipping containers, slime wiped from their bodies...). Much more could be mentioned as possible sources of mortality, but I strongly suspect these anomalous losses are due to environmental stressors. Bob Fenner> Ill Damsel I have a 40 gallon tank that is around 4 months old. All levels are fine and most of the fish have been in there for at least 2-3 months. <Define fine please> The only thing newly introduced around a month ago have been some cleaner shrimp and some tiny crabs (hermit & baby stone). In the last week my Electric Blue Damsel has gone from being extremely social and having his little areas to hide to floating towards the surface and barely being able to swim straight. He has also lost the vibrancy in his color. I was sure he was a goner last week because all he did was float sideways at the top of the tank looking as if he was gulping at air. He has held on like this for over a week, rarely eating food, if any. I have separated him from the other fish in an isolation tank within the same large tank to try and revive him somehow, so the other fish won't eat the food so fast, but he does not seem to be getting better. Is this common? <No actually it sounds like he is sick> Is there something I can do to help him? <I would suggest an antibiotic, perhaps something like Melafix, can you see any signs of ANYTHING on him? dots, or anything out of the usual on him?> Or is he just on his way out? <Hopefully not> He looks so pathetic I feel awful for him. <A quarantine tank would be idea where you could treat him in isolation but if not treating the tank. Just be very careful that you don't treat with something so strong it wipes out your entire bacterial bed.> Any advice you could give me would be greatly appreciated. <Good luck, MacL> Regards, Tina 3 spot domino damsel Hi there, Just a quick question: One of 2 dominos seems to have a whitish thing between the two bottom front fins. Has it overeaten and busted, is pregnant or sick? It's behavior is normal, swims around and still eats as usual. Any advice would be appreciated. Thank you. ***Hello Minh, It's been a few days since you sent this query. Sorry, it was a busy weekend! How does the fish look now? It could be ich in which case you will need to treat the fish with hypo, or it could be a piece of sand in the slime coat. Please update. Jim *** Red Spot on Chromis (7/12/04) Hi Bob <Steve Allen with you tonight.> Great site, but I cannot find a reference to this problem. I have just noticed a small reddish spot about 3mm on one side of one of my green Chromis. So far he looks fine, should I be concerned? regards, Ian <Well, it could be an abrasion of some sort, or the start of a bacterial infection. You might want to try saltwater coating (Stress-Coat-type) solution that might help it heal. Bear in mind that you will need to turn your skimmer off for a couple of days. On the other hand, if you are keeping your water in tip-top shape, you might just watch and it could heal on its own. If it starts to spread, you would probably be best moving to a hospital tank and treating there. Hope this helps.> Damsel with mouth stuck open I have a
damsel that's been in my tank for a good 3 months, and today I
noticed his mouth is constantly open. My other 3 damsels all open &
close their mouths constantly. This one has not been like this for more
than half a day, because he was eating last night. I put some food in
the tank a little while ago and he swam to it, but didn't even
attempt to eat it. Is this lockjaw, or is that only when the mouth is
locked shut? Any help you could offer would be greatly appreciated.
Thanks, Dean <Good observation. Not "lockjaw" as in a
paralysis from an infection, but likely either an injury resultant from
banging into something in the tank or something lodged in an
articulating joint in this fish's mouth. If this is still the case
(that is, if the situation hasn't remedied itself within a day) I
might try catching the fish, gently opening the mouth a bit more, and
even more gently trying to close it. Bob Fenner>
Damsels in Distress! >HI there, >>Hi there yourself. >We have just set up a 55 gal. saltwater tank in our office, and had it running no fish for a few days, the salinity was 1.025, pH 8.4, nit. 0 & ammonia 0. Temperature is 75. >>There *should* be no ammonia, nitrite, or nitrate in an empty tank. You need to add something to start culturing nitrifying bacteria in order to get those readings to do their thang. >Well we then added 5 damsels. 1 large 4 stripe, 1 tiny domino, 2 yellow tail and one blue. >>Oh, crap. Well, that'll do it! For future reference, it's now the accepted method to cycle fishless. Do search our site for "nitrogen cycle" and "cycling" to understand both how and why it works. Methods used are via food of some sort, raw shrimp, frozen, et al, placed into the tank and allowed to decompose - test for subsequent spikes first in ammonia, then nitrite. When those FALL, and nitrate comes up, you know you've established colonies of nitrifying bacteria. >The domino didn't look well on the trip home and when we put them in the tank, he stayed near the bottom and didn't swim around much. >>This doesn't sound too good. If it was a short trip, the shop should give you credit on this animal, as it clearly wasn't healthy to begin with. >The other damsels appeared to be healthy and swam around and ate a few marine flakes. >>Right, but maybe not for long, eh? >Being fairly new to the hobby, we did not set up a quarantine tank but that is definitely on the next to do list before any more fish are added. >>Ok, I'd like you to know it doesn't have to be an "aquarium". Rubbermaid makes great stackable containers that are about 30 gallons and perfect for "q/t on the fly". A filter and a heater and you are set to go! >Anyway, we lost the domino the next morning, and that same day the lighter yellow tail what appeared to be a white mustache. No other spots but he seemed to not want to swim and stayed near the bottom of the tank and wasn't swimming very well. Well, he died the same night. >>Too much too fast, my friend. The domino wasn't well, as I mentioned, but the next damsel likely succumbed to high ammonia/nitrite. All too common in this size system without water changes. >When we removed him from the tank he was completely white. >>Fish decompose VERY quickly once dead, as in FAST BAM! >I looked up on your site to see what possibly was going on. I don't think it's ich, possibly velvet? >>You would definitely be seeing other signs in my opinion, but their presence absolutely cannot be ruled out. >I don't know though the domino had no lesions or white spots or any signs of disease other than his behavior. Could the yellow tail have had a fungus? >>Much less likely, though I would be interested in seeing how that whole batch of fish is currently doing (what remains at the shop)! >It came on quite rapidly. Anyway, while I was at home my boss said that the 4 stripe had also died. He had shown no other signs of disease, no white spots lesions etc, but had suddenly started staying near the bottom and hiding. He wasn't white either when he died. Now the other yellow tail is hiding and acting like the others did but is also scratching himself on the rock. I decided after reading about parasites/disease to try a fresh water bath for the remaining 2 damsels, and also performed a water change of 5 gal. didn't add any salt to the new water because I wanted the gravity/salinity to lower a bit, which it did to 1.024. Ph was also high before the water change @ 8.6 and nit. were <0.3 and ammonia was 1.5 >>Yeeowch! That is a very high ammonia level, definitely high enough to kill quickly. High pH (and yours was borderline) makes its effects even worse. However, be VERY CAREFUL messing about with pH! I'd like you to search on acclimation procedures on our site, as well as the quarantine stuff. >So I wanted those #'s to come down a bit. Anyway, I dipped each fish in a freshwater bath (same temp/ph as the tank water) for 5 minutes and then returned them to the tank. >>Good job, but it's not going to be enough, as they've gone right back into the water with the high ammonia, yes? >For a while they seemed to be doing better, but now they are hiding again and don't seem to want to come out. They aren't looking too good, and I don't know what else to do for them. >>A very large water change - as in 40 gallons or more. Do NOT vacuum or mess around with the tank walls or anything. You *may* be able to boost nitrifiers colonies with a product I am unfamiliar with personally, but hear great things about - Bio-Spira. >The yellow tail doesn't swim much, just stays in the same spot sort of hovering. They don't appear to have any spots on them though. ????? any suggestions what might be going on with these fish and what we should do? >>As above, and double check on the source of those fish, I am currently suspect as they *should* have all made it home. >Thanks so much for your time, and have a great day! Sirina from California >>You're very welcome, Sirina. Cover those bases, and you should be able to get this tank going well, although I cannot say how well the fish you currently have will do in the long run. Marina Suspected Illness (4/5/04) Hello fish husbandry gods, <Mere mortal Steve Allen attempting to help tonight.> I have a blue damsel that hasn't eaten in 5-6 days. Had this fish for about 1.5 years and he's usually quite the aggressive eater. Now seems spaced out, meek and just acting strangely in general. I have just been waiting it out, looking for symptoms with which to try to diagnose something. I only once saw it excrete some white feces. Other than that I could not say there is anything visible. [The fish also has a very small spot on his side that has been there for months, hasn't changed ever, so small I could not describe.] <If present & unchanged for months, it is highly doubtful that it is pathologic.> I have a 55 gal with only an ocellaris and a large hermit crab in it otherwise. Still, I faithfully change 4 gallons weekly. <Smart> Admittedly I do not test water frequently and do not currently have any kits to do so. <I think you'd better test just to be sure since your fish is having symptoms that could be due to toxicity.> I don't overfeed and maintain well so haven't focused there. What I am wondering is should I quarantine, and if so what medicine--if any--do you think I might use? The only recent change in the system was the addition of a ball of Chaetomorpha. <Sometimes even algae comes equipped with parasites or other pathogens.> Thanks bunch, Lance. <I, too, am puzzled by these symptoms. I'd advise testing or having your LFS test to be certain the parameters are OK. If so, I'd be worried about illness. If it doesn't perk up very soon, you'd best catch it and keep it in a QT and consider treatment for an internal parasite. It could be constipated. This happens sometimes. Read about treating this on WWM. Hope this helps.> Damsel Getting Better (4/13/03) Hello, Steve Allen responded to my question regarding a sick Damsel a week ago, and I thank him. The bugger (the damsel, not Steve) didn't eat for a week and was acting vaguely strange--but no clear symptoms. I decided to add some Epsom salt just in case that was it. (This fish had that problem before--clearly--but acted, well, differently.) Not sure if it was that this time, but the damsel slowly improved and began eating again. My new question is about foods. Could bad food cause illness and/or constipation? I have very few fish, and the food in the too large containers lasts longer than the expiration dates, I am sure. <Hard to say what "expiration" dates really mean. It's highly doubtful that the food becomes harmful, but its nutritional value goes down gradually over time.> Why do they make the food containers so large? (Yes, rhetorical :-) Should I freeze some of it upon opening? Thanks to all! <You might consider adding frozen foods such as Mysis, squid, etc. Variety is important both for nutrition and to prevent constipation. Another option would be to buy seafood in the grocery store and chop it finely (partially frozen in a food processor should shred to an edible size. Then freeze in in small portions in snack bags or one of those mini ice-cube trays. I buy a seafood mix at Albertson's that includes squid, mussels, octopus and other disgusting things that fish love. There's also a great recipe for frozen food in Bob Fenner's "The Conscientious Marine Aquarist." Hope this helps, Steve Allen.> Lance Sick Chromis (3/24/04) Hello, <Hi. Steve Allen
tonight.> This is my first time sending in a question so I'm not
entirely sure how this works. <Give the sorts of details you've
included and ask. Best to do some research first. Sometimes we
can't give a definitive answer and will refer you to places you can
read more. It's hard to be sure sometimes what a problem is without
seeing it.> I have had a saltwater 20 gallon tank running for about
two months now. For the first few weeks, I just had live rock and
snails in there and 3 weeks ago, I added 2 Blue Green Chromis to help
in cycling the tank, which occurred within a week of introducing them.
They have been doing very well but three days ago, I noticed on the
larger Chromis two reddish sore-looking spots, one near the tail end of
his body (a bit faded now) and one above his head. He spends most of
his time underneath the live rock, <Odd, Chromis are usually out and
about.> and I originally thought that he had just scraped himself on
the jagged edges of the rock darting in and out of his favourite hiding
places. I became concerned yesterday when I noticed that he was fairly
lethargic, not eating much and his breathing seemed rapid (but then I
cannot quite remember at what rate he used to breathe, but he IS
breathing more rapidly <uh, oh> than the other smaller Chromis,
which is doing very well; he is very active, and eating very
regularly). The water chemistry is good <zero ammonia and nitrite?
low nitrates?> and I even performed a partial water change last
night, in hopes that it would somehow help. I was wondering if you have
any suggestions on what he could be suffering from? I'm not sure if
a cut or abrasion would affect a fish's behaviour this much and
I'm concerned it may be a parasite or bacterial infection and I
would like to treat it before it spreads to the younger Chromis.
<Appropriate concerns indeed.> Any help would be greatly
appreciated. (Also, with a partial water change done after cycling, the
protein skimmer needed constant adjustment of the air flow in order to
work properly again, I still have to tinker around with it every now
and then...<It takes a while.> Could that have caused a breeding
ground for bacteria or parasites?) <Many factors contribute.>
Looking forward to your reply, Sonia <The symptoms are very
concerning for a parasitic infection such as Cryptocaryon or
Amyloodinium. The red spots should like abrasions or bacterial
infection. Have you noticed him scratching on the rocks or sand?
I'd suggest you read about parasitic and bacterial infections on
WWM, as well as quarantine. Reading this should help you decide the
best course of action. Hope this helps.> Injured Chromis? Good morning. Yesterday afternoon I bought 3 blue-green Chromis, which are to be the first additions to our 75 gallon tank. After a 6 minute dip in buffered fresh water and Methylene blue, I transferred them to a 10 gallon quarantine tank. All tolerated the dip well, and by evening were swimming together around their new temporary home. Although all looked healthy last night, this morning one of them has a bruise-like vertical line through his mid-section. Only on one side. He's swimming normally, breathing normally, doesn't appear stressed. Having no fish experience, my best guess is a bruise - maybe a net injury or something? <Likely so... may develop into a secondary (bacterial) infection> If it is a bruise, will it heal on its own with good water quality. and how long before I should see improvement? <Should and a week or two> Please let me know if there are other possibilities I should be aware of, or what I should be watching for/expecting. Thanks. Suzanne <Be chatting, Bob Fenner> Damsel In Distress! Hi folks! <Hello! Scott F. here today!> I have a 29 gallon tank with a 20 gallon sump (if this starts to sound familiar, my partner wrote in a couple days ago about something odd and fuzzy we had growing in the sump). The 29 gal. has three Blue Devil damsels, three Turbo snails, and two Peppermint Shrimp. We've had the damsels for a little over a month; started out with five, but two died shortly after we brought them home. One damsel was doing well, but at the expense of the other two (he's very territorial and thinks the whole tank is his territory), so for the time being we've got a tank divider set up, with the mean one on one side and the two stressed damsels on the other. Haven't quite figured out what we'll do long term, but in the short term the idea was to try to keep all three alive. One of the stressed damsels is making a big comeback -- he eats well, some missing scales are growing back, and his color has massively improved. <Glad to hear that!> The other isn't doing so well. It's the smallest of the three, and after separating them out like this, we realized just how thin the poor little guy is. We thought this was due to being driven away from the food, but it looks like he might not be eating at all. We give them a little bit of flake food in the morning, and either more flakes or another food in the evening. The littlest fish will take food into his mouth, but spits it back out again. They all do this to break up large particles, but after watching him closely for the past couple days I have yet to see him actually eat anything at all -- he seems to spit everything back out. He's listless in general, and doesn't seem very enthusiastic about the food. We've tried the aforementioned flakes, shredded shrimp (frozen stuff thawed), tiny bits of spinach, dried seaweed, and even bread crumbs. The other fish eat everything happily, but nothing seems to tempt him, and he's really rather disturbingly gaunt -- the skull is sharply defined, and the flesh seems to dent in along the spine, sort of like he's been partially deflated or something. Any ideas? Thanks, Kirsten <Well, Kirsten, your idea of trying a variety of foods makes a lot of sense. However, I'd try some more nutritious frozen foods, such as Mysis shrimp, "Formula" foods, and maybe some chopped squid. Also, you could try to administer some liquid vitamin preparations, such as Vita Chem, etc. directly into the water (if you're keeping this guy in a separate treatment aquarium, of course). Since fishes drink, this guy can take in some nutrition directly from the water this way. And, it may just hold him over until he comes around and eats again. Hang in there- good luck with this little guy! Let's keep our fingers crossed...Regards, Scott F> Swollen Eye On The Damselfish Guy... I added a Jewel damsel 2 days ago to my 55 gal. This evening I noticed one eye is kinda white and bulging out. What is going on? No other spots, etc. to him or any other fish. <If the swelling is just in one eye, it is probably due to some sort of injury or localized trauma. This condition can be alleviated by the use of Epsom salt in the water (ideally performed in a separate treatment tank) to help draw out the fluid causing swelling> Tank is well established and have had no outbreaks in the past. I am wondering if it has been injured somehow. I hate to treat the whole tank when nothing else has problems. I do not have a hospital tank as I have never had any problems in the past. Thanks for any advice you can give. Michael Linkous <Well, Michael- my recommendation is to treat the fish in a separate aquarium. Since you don't have one, you could "jury-rig" something with a large Rubbermaid container or other plastic container of suitable size. This should do the trick as a temporary "hospital". Good luck!
