is there any way u can keep a rbp with SA/CA cichlid without one killing the other and not have a 1000000000000000 gallon tank becuase I was thinking of getting one when i got a bigger tank?
if so wich ones and what size tank
No dude, bad idea. When pirahnas are alone they are wusses, and will probably be killed by the SA/CA's, and when in groups, they will kill your other fish. Get one or the other.
