So I have 4 oto cats in a 10 gallon tank (they'll be moving into a 45 in a week or two) but one of them has a 'white' splotch on its face. The others are perfectly healthy and, for the most part, this one is too. They're all eating well, are nice plump, and are swimming around. I just don't know what's up with this one. The 'white' started at the gills and has covered its face now.
Does anyone have any idea why this guy is losing his color?
