I picked up three Pelvicachromis subocellatus from my LFS two days ago and one looks pretty sickly. Many of the scales on her sides are damaged, which I thought was fungus at first. She was like this when I got her but I didn’t notice it at the store. Is this a recognizable disease I could treat? She’s active and eating so I’m optimistic she’ll improve but I don’t have much experience with fish disease. The other female looks great and the other male, while a little thin, also seems healthy.
