Yellow tang sudden death

[Izwei]

Hi all,

My captive bred yellow tang suddenly died out of nowhere while I'm away today. I found it on the sand bed. All my other fishes are fine. I couldn't figure out why, I had the fish for more than 1 and half year. No new additions recently also. It is also quite plump, dun have any obvious physcial damage as well ick. I can show the photo if need to. Think not good to post in the forum. I do have a another bigger blue hippo tang, he will pick on it once in a while but not super agressive as I dont see any obvious fight marks. Any possible reasons?

Thanks guys.

I had a same issue with my yellow tang 20 days back. I saw the cctv footage and nothing T all, swimming properly and then suddenly acted strange, next thing collapsed on sand bed before I could figure out. Other fish all were OK so only natural thing I can think of is end of life cycle

There could be a number of reason like fish aggression from your existing tank especially if you have other tang inside your fish tank.

Hi, thanks for the replies. I suspect is my blue tang. Hes getting too big, getting more agressive as he grow. Out growing the tank alr.
