Is this fluke?

My sand sifting goby has been eating less and during the past month and has been bullied by one of the clowns and a dottyback. Last couple days it has developed this (pic) around his eye. I’ve had no luck catching him. Is this a parasite?

Looks like damage from the fish you listed. Dottybacks can be real jerks.

Looks like decision time. Use a clear trap and trap one or the other. Your call.
