My O is about 6-7 inches long right now, what would be a good diet to feed him? I have one more question, how do you guys feed your oscars? I used to just put the food in for him, but one day I must have been taking too long with a shrimp and he jumped and took it from my hand... I feed my fish everyday, and one day I didn't feed him and the next day is when he jumped for the shimp... I used to hold my hand in the water to feed him krill too.
