Fat Yellow tang?

[derek12261984]

Not eating is a serious symptom. There isn't much you can do in terms of treating that, other than seeing if it will clear in time.

Can you post a video of the fish now? It might show some symptoms that could direct us in a different direction....

I’ll definitely grab a video when I get home. I’m hoping whatever is going on will pass. I love this little guy… not to mention captive bred tangs are not cheap.

Here’s a video of the little guy. No improvement thus far. He was not interested in any mysis shrimp today when I fed the others.

As Jay stated - hold off feeding for 12-24 and see if there is a reduction with that swelling

Will do! I will hold off till tomorrow evening. I did pick up some Brine shrimp/spiralina tonight at the store. Are you able to see the video? For some reason, it’s not letting me view it.

And thank you so much again for all of your help! I can’t tell you how much I appreciate it

Here’s a link in case you can’t view the vid. For some reason, the webpage is not letting me upload videos directly.

It does appear to be constipation/blockage to me. Hopefully it can release the feces without rupturing. You might read about adding Epsom salts. That is a remedy for freshwater fish, marine fish are already bathing in magnesium sulfate. Epsom salts in food can help marine fish, but of course, they must be eating.

Update: thanks all for your help. Things are much better today.

ill definitely check that out! Just an update; he seems to be back to his sweet little hatefilled self this morning! Swimming around the tank (attempting to shank any would be pedestrian in the way) like usual and he looks much less bloated than he did yesterday. I’m assuming he got something out overnight. He still looks fat, but much better. I’m going to slow down on feedings and start introducing brine shrimp as apposed to mysis all the time. After doing further research, @vetteguy53081 was correct in his assertion: this seems to be primarily a biota thing. Almost every thread I found which was similar was linked to captive bred YTs. I’m definitely not disparaging them in anyway as I love what they’re doing for the pet trade. It’s just one of those variables that nobody could anticipate. Thanks for your help again. I’ve always been a reptile guy and I’m fairly new to the world of saltwater fish.

Excellent and as expected
Feed small portions in lieu of big ones

He’s still not eating, but is more active today. I’m going to see how he does over the next day or two and if he hasn’t eaten, I’ll toss him in QT with the kana

Will do! That’s actually what I tried today. He’s not interested still, but I’ll give him some time.

Still not able to get him to eat. He’s actually ok, but still bloated. Should I go ahead and start treating with kana?

the answer but it is absorbed by the fish and worth a try. Add aeration with this treatment using air stone.
Try plankton or Mysis shrimp and universally, I prefer LRS fish frenzy. Most fish will not turn down brine shrimp.
Any fish you can see may be intimidating him?

No he is the ruler of the roost, and the biggest fish in the tank. I’ll definitely get a little air stone out. I have a little 10 gallon aquarium with a hang on the back filter I’ll be using, but can always add a secondary filter if need be. I hate moving fish from one aquarium to another because it stresses them out so bad. Should I give it another day or do you think he’ll decline to rapidly if I wait?

Assuming you're planning to use kanamycin for a bacterial infection in the GI tract? - There is at least some data out there suggesting the oral route is the most effective - though oral dosing can be less simple (since the fish is not eating, and there can be toxicity if it decides to eat too much).

From the U of FL: The aminoglycosides, including gentamicin, neomycin, kanamycin, and amikacin, are very effective against gram-negative bacteria infections when administered by injection. Unfortunately, this group has also been shown to cause kidney damage in fish when administered by this technique.

As a group, these antibiotics are not considered effective when used in oral or bath treatments. A couple of exceptions may be kanamycin and neomycin, both of which may be effective against external infections if used in bath treatments. In addition, kanamycin is also believed to be effective when mixed with feed to treat gastrointestinal bacterial infections (Gilmartin, Camp and Lewis 1976).

Stress is temporary and I’ve seen this more than once with good outcome

OK sounds good. I will mix it up in my secondary tank and toss them in for a couple days. Thanks for all your help!

The goal of the use for this stuff is to induce diarrhea as it is a side effect of the medication. I’m not actually treating bacterial infections.

Going to continue this thread just to document the outcome. It seems that several people have had this issue with biota yellow tangs. Hopefully this will assist with those struggling in the future. The yellow tang has been moved to a hospital tank below my display. I was using the tank to grow cheato, so I did leave some in the tank for him should he want to eat. I dosed the kanaplex at the recommended dose and will redose every 2 days. I’ve got my fingers crossed for him to pull through, but not holding my breath.
