i used to have 5 red belly piranha's
then there was 4
a little while later there was 3
2
then thought fook this and sold em to my mate.
We used to feed em all sorts - best was going down to the garden centre and buy goldfish or guppies and feed em to the piranhas
me and a mate stayed up until 2 am once watching the piranhas eat the guppies. even switched the lights off and tv

but the guppies stayed at the top of the water and the piranhas downt eh bottom.
