Thanks all.
He eats mainly tilapia. Sometimes ill stuff the fillets with pellets.
I also feed him goldfish, sunnies, cichlids, barbs, etc
Tank is small, 180g, but there is ~4000gph of current in the tank and he is very happy. I have a 6'x3'x27" 300g for him, just need to fill it with water. The tank used to be viewed from both sides. It is not any longer, so I just slid 2 pieces of black cardboard behind it; you can see it is water damaged in some areas.
