When i set up my 75 gallon tank over christmas i moved a green terror into the tank to make sure my quick cycle took. The tank has a large strawberry pot and lots of hiding spaces. There is also a very angry brandtii in the tank, who wants his tank mate dead more then anything. Unfortunately, Piranhas are completely goverened by anger and rage therefore he keeps allowing himself to be fooled by this little [email protected]$%^$. Anybody else have simliar experiences?
