yesterday i noticed 2 small spots on my indo's jaw. they're not red or inflamed or anything. it kind of looks like the scales are scrapped off. it eats health, no live food, just pellets. he's the aggressor in the tank so its not getting bullied. its housed with a few bichirs, a flagtail and bellycrawler in my 75g. no2, no3, and ammonia are all 0 and has plenty of filtration. anyone seen this before? should i be worried? it looks like there's another white spot forming on the other said of its jaw. here's two pics
