I got my info from many and they all said that a 125 was the min tank size that they would be fine. So I bought the fish and he is in the 125 with the fluval fx4. But now I hearing that the tank is to small. But my landlord told me that my places floor could not handle any more than 125. Plus seeing a tank that is bigger than a 125 in Springfield is not really heard of. Unless you go to bass pro. So now I am going to have to find my Jardini and new home.
