I added a Pair of Blue/Green Chromis to my Tank about 3 weeks ago. I noticed a white bump on one of thier heads a few days after being in the tank. The bump remained and didnt change at all. none of my other fish showed anything at all either. Today when feeding the fish I noticed the bump doubled in size and is now reddish brown. The fish seems fine he still ate like crazy and is swimmingy around normally. There is no way I can catch this fish to put him in a hospital tank unless its absolutly nessesary (my tank is extremly populated and has dense rockwork that hasnt moved in over 2 years). The only other fish in the tank right now are a Maroon Clown Pair, the other Chromis, and a Coral Beauty . Its definitly not ick. any ideas to what this could be???
thanks
