Hi all, could I have some advise please. One of my opauline gourami's has always been smaller and not growing as quick as the other that I bought at the same time and today i noticed he's got a red patch under one of his eyes, what could this be ? My water stats are fine, i've had them about 6 months, and the other tankmates include some cory julli's, rosey tetra's and a silver shark. Any help is much appreciated
cheers
