Help, filefish getting attacked
Hey all, I introduced a file fish to my system about a week ago and everything has been going great with it. This morning I noticed he didn't go after food and when I looked closer I think his bottom fin was bitten off. I would assume either my yellow tang or flame angel thought it was a piece of algae. He is hiding behind a rock and I just want to know if I should/can do anything.
I put in prime to promote its slime coat but that's all I could think to do
