Tang - Fin

I think you've just answered your own question. You have a large tang in a 34g tank. He's probably stressed because of the lack of space to swim. I don't know if that is the cause of the dorsal fin issue, but it's not a good thing. I would sell him to someone with a big enough tank for him.

 

Or, you could always upgrade to a bigger tank!!

Wow... it amazes me the size tanks that tangs get put into. I feel bad for my sailfin tang that is in my 220 gallon because she is TOO BIG for it. A yellow tang in less than a 50 gallon, I imagine, is enough to kill it or at least make it sick. Tangs swim alot and need room.

 

Sell the fish or get it a bigger tank! Also make sure you are feeding it algae sheets/nori frequently.

We have always made sure he had fresh and plentiful Nori to eat all day long. I guess I should have said healthy and not a
