Well I found out why he's skinny! Lol I feed him alot of wax worms and they float, well when I feed him I turn off the lights and I stayed down their to watch tonight. The bullhead already ate and started patroling the tank.. well he began to skim the top of the water and he ate the wax worms!! Crazy piggy catfish!! I couldn't believe that... so I got big earthworm and cut it in pieces and the bluegill ate that... ^_^'
