it's not so much they were a problem, it's that they are bloody STUPID loloolol I tried to keep a school of between 6-12 at all times and the same 3 kept killing the rest of the school. It didn't make sense for a fish that prefers to school, so I just said ''screw it, im not gonna keep buying them if they don't want tankmates"Yeah I have a low tolerance for problem fish myself.
All my dithers were eventually killed and eaten - danios, TBs, Platys, Guppys, Mollys - all gone. Just cichlids and bottom-feeders now and a few shark-minnows
