Ok I. Got a wolf fish 1 day ago he's in the tank with 2 smaller cichlids and two small parrots my gf's fish...and I noticed after a day he seems very stressed and has been in a cave the whole time..he hasn't eaten anything. ..I tried shrimp,feeders,and no luck..I'm curious if he is just taking time to get settled in...also the otther fish I think took advantage of his passive behavior and bit his dorsel fin a bit will it heal?? One more thing when I first got him the botom of his mouth was kinda raw and pink a little bit on the top too I think iys from him bumping into the previous tank??? Is it common and will it heal?? Any advice or help would be greatly apprstiated thanks!
