Please help me with this if you can. Just bought these fish on Sunday May 11th at a store that is new to me. Asked for two Chromis from the tech in the store. Didnt look at the fish before I left the store, I know dumb, feel like I got took advantage of. My friends wouldnt drop me off at a store because of a problem and I don't wanna give up on him. One of the chromis' has a orange protrusion coming out of his head. It resembles a wart on the hand in shape and appearance. Cant seem to find anything on it by searching google or peering around on here. Sorry if this has been covered before.
