I originally had 4, then 3 died. I think it was cos of bad water quality and also because the tank they were in was too small, and I had just the 1 for a while which is quite big now, like about 8inch, and they can grow up to 12inch. I then got a bigger tank when i found some more for sale, and so had 4 again, but 1 is twice as big as the new ones, and as a result, he ate one of them :S. Got back from work and he had just left the head floating around :S.
So now i have 3 Piranha's. They make good pets, and are lightning fast, so interesting to watch when eating

Larry, the biggest one


The other two smaller ones
