I have two rbp and a pleco that will soon be living in a 55g tank. right now there only about two inch so im keeping them in a 10g. When I move them to the big tank for the first few months they will be rather hard to spot because of there size so I was wondering about some tank mates. so far they have been getting along great with the pleco that I added a month ago. I know that pirahnas like to bite the fins off other fish kept with them so what about a cray fish or even a turtle? I was just wondering if it could work? any sujestions any one?
