Who Gives A Fish Forums

I think the first is actually a Convict Cichlid, not one of the ones I was looking at - I'm guessing the store just had a mix of different types of cichlids, not just African cichlids.

Honestly, I wouldn't worry about it, it seems pretty harmless to me. Let nature take its course, it'll either die off on its own or your fish will probably just peck at it.
