dont plan on buying a fish unless you have a tank that is ready and cycled. It all depends on what size tank your planning on putting these fish in. You can start with a baby shoal or you can have a single piranha(serras.) but serras might be very active or in most chases they sit in the corner all day.penngomifan;786146; said:right now i dont know what the hell i want anymore!!! i have a dovi cichlid as of now, baby, about 2 inches, but now im thinking of getting a black pirnah or a elongtus.... hopefully i spelled that right, anyways, how do these guys compare, would u consider either one tougher than a dovi???? i meen imo a rhom would chomp a dovi even though the dovi is more aggresive, i just dont see how a dovi would be able to hang with a rhom, .... well anyways thx........ and i know i live in california and they are illegal, but im just talking about this in a fiction sence........ so please reply.......
