	Will they eat eachother?
~Mista Psycho~ Hobbyist Posts: 125 Kudos: 84 Votes: 12 Registered: 13-Mar-2005	in my tank i have 2 Red bellied piranhas and 3 accidental red bellied pacus. i have been meaning to take the pacus back to the shop and go and get some piranhas but i just havent had the time lately. plus they have made a really good shoal with no signs of aggression. and to be honest i've grown quite attached to them. my question is will the piranhas eat the pacus, and can they tell that the pacus arent piranhas. because they all swim around the tank together.

Some species' piranha-like coloration may, in truth, be a form of protective mimicry; juvenile pacu occasionally school with red-bellies in the wild. As for the risk of predation, I feel the possibility of any injuries more severe than minor nipping to be no greater than if your pacu were indeed fellow piranha.

I urge you to take them back to the store. Last edited by Veneer at 17-Apr-2005 14:13 Last edited by Veneer at 17-Apr-2005 14:27
