So I currently have a single balloon belly (I think) fry in my 10 gallon. Soon I'm going to add a few dwarf platies, maybe some von rio tetras. I don't know. But regardless, I already have an algae problem starting. So I would like to get at least one oto- do they do better in pairs? Should I just feed algae wafers? I really know very little about them, so would appreciate any advice. Thanks!
