I noticed today our purple tang was hiding and fed extra to entice him to come out and he wouldn't take food.
I have never noticed problems/bullying from other fish, but it clearly looks like it to me.
1. Could this be anything other than fish aggression?
2. Anything I can do to help chances of success? I caught him and have him in my sump to keep same parameters. I could move to QT with copper/treatment but didn't want to do it before checking here first.
Thank you!
