6 Red Belly Piranhas, 6-8inches, Must Go

6 Red Belly Piranhas, 6-8inches, Must Go Hi There I have 6 RBP's. Ive had them since they were the size of a 20p coin, they are now about a year old. I need their tank for a breeding project, buyer must bring a bucket & a couple of nets as they do bite through bags & nets :) They are all healthy and eat anything thats put in the tank. Hope they goto a loving home. £120 ono for all 6.
