My friend and I got into an argument about the bare min. number of piranha you can have togather safely, I said 6 and he said 3. Now I know that having 3 COULD work but I think that they success rate would be MUCH higher having 6 than 3.
So if you would please give your opinion, personal experinces, ect...
(The tank size was never mentioned in our arguement)
