I think I am going to lose one of my three green chromis's that I bought on sunday. He looks weak and and is "panting". I also noticed 2 little "patches" on his back, right after I put him in my tank from the fish store. My two Clowns are now picking on him. I feel real bad for the little guy and hope he pulls through, I guess I don't really know what to do. My other fishes are very active and eating. Oh yeah, I also check my perameters lastnight and everthing was fine. Any insight is appreciated.
