A small whitish spot had appeared on the head of my black balloon molly. I've been treating the whole tank with Pimafix, but this morning I noticed that one of her frys was all the time picking on her, exactly on the spot where the white patch is. I went out and when I came back later I saw that the scales on the top of her head look like they are "cracking". You know when the dirt is so dry (like in the desert) it looks like it's cracking... I'm sorry but that's the best description I can give
Any idea of what this could be??
