My biggest leopard bush fish is when I put food in the tank I put some at the far left hand side some in the middle and some at the far right hand side this really confuses him as he dose'nt know where to start while he is deciding where to go the other fish get a chance to get some of the food or he will eat the lot. It is quite funny watching him dart from one end of the tank to the other trying to eat all of the food he is twice the size of my other bush fish even though he was smaller when I bought them I have to target feed the smaller one some times.
