The Pygocentrus species were originally placed within Serrasalmus, along with many other would-be piranha species that are now habituated into other genera. As one might expect, there is no definitive tank size for keeping piranha. Keeping pygos as a group will require a large tank, as the adult fish are capable of attaining 14" or more depending on the species. Realistically, a 6' x 2' x 2' (180cm x 60cm x 60cm) will be needed for a group of 6 - 8 fish. Obviously, juvenile fish can be grown on in smaller tanks but there should always be consideration of the long term accommodation plans. Piranha and tank mates can be a very hazardous combination! As a general rule, all of the Pygocentrus species will live together, unless there are significant size differences between the fish. If some of the tank inhabitants are much smaller, then there is a very real chance they will be eaten. However, this process can also work in reverse because, if there are a number of smaller pygos in a tank and one or two large fish, the smaller fish can sometimes "gang up" on the large fish and kill it, due to the perceived threat of having the large fish in the same territory as the smaller ones. 1 out of 1 found this valuable.
