Alright, so one of my oto's has now developed this in my tank so I know something is up and mine from the pet store had this instead of an injury. His overall health seems to be suffering too, he's not a fat and happy oto. Any ideas? I'm going to snap some more photos, see if I can get anything better, but the white seems to have a fuzzy texture to it.
Bump: More pics added with better quality
