I have one 8" red in a 29gal tank and when I approach the tank to feed him, he goes completely ballistic. It seems he can't wait for me to drop a feeder, chicken, or shrimp in the tank. I really am afraid he may lunge up one day and mistaken my hand for food. This behavior reminds me of oscars and red devils i've had in the past. All I know is that i'm very cautious when feeding him. Does anyone else have this problem?
