i have an oscar that is at least 4 months old now and is almost 6 inches long. i had it in a 125 with my other ciclids. they are all of the same size typically. there is also a red devil in this tank with it. it started harrassing it but not really too badly. so i took the oscar out and put it in my OTHER 125 which im using to grow out a gar, knifefish and 4 bichirs. the oscar was still the biggest. welll anyway a few days later i found him with his left side all peeling off. im confused becasue hes still swimming around and eating, but his sxcales are all falling off... any suggestions?
