So I know it's hard to see but he was close enough to the side to take a picture. 40 gallon tank. We only have three fish in it. A common pleco, a comet, and this guy.
I've read about pleco eating slime coat off but this all happened in one night and we've never seen him go near the other two fish.
Tank is cycled and has been steadily at 0 nitrites and ammonia for over a month. Should I seperate him?
