I noticed this morning that one of my Sterbai Cories had a white lump. This is the second incident in my tank, after the death of one of my Cardinal Tetras although I assume that was natural. All the other Sterbai Cories seem completely fine and are behaving normally. All other fish are fine too.
He seems to be brushing against plants and the tank glass a lot, as if he's trying to get it off. He's also at the front of the tank a lot more, which is unusual for my Sterbais.
