Hey everyone, Im new here, and I have one red belly that's about 5 inches in a 55 gallon tank. I have read that they are more agressive and happy in groups. Do you think I should add two more? Is it a must? Or is it ok to keep one? Also, I want the fish to grow as big as possible, how big would 3 grow in a 55 gallon? Thanks in advance.

get 2 more, and they will should be able to reach full growth in a 55. It is hard to say what size that will be but they are capable of reaching 12"+, however this is rare.

Get two more. Make sure though that the others are about the same size as the one you already have or one of the piranhas will be eaten by another.

yes get 2 more and if they are happy and well feed there
is no doubt that they will reach 12 inches and you might
even have them spawn a time or two
