LBathory;2773651; said:everything will eventually end up food. there is no exception. it is impossible to keep a piranha with tank mates in a long term situation, even schools will eventually be destroyed.
i disagree..
it depends on the temperament of the piranhas.. i have had my piranhas for 6-7 months now.. and for the 6-7 months they were always with a pleco.. my pleco is still alive and with a full tail..
i was even able to keep a few guppies and a few minnows for a period of 2 months..
