Two weeks ago I picked up a clown tang, I’ve read about them possibly being aggressive but my girlfriend wanted him, so we compromised and got him. Every now and then I’ll look at the tank and it will look like the clown tang’s nibbling on the side of my filefish. Before I consider getting rid of him, are there any countermeasures I can take? Maybe i’m not feeding enough, I don’t know. The filefish has been pretty skittish since adding the tang. Any help is appreciated.
