i find there both pretty easy to feed but the Oscar is way easier! When feeding time comes around the Oscar will sit in one spot and wait for me to feed him. where as the Green terror shoots around all over the place. Once, i feed the Oscar he will follow my hand around waiting for more food to drop. But the GT will take off into the back of the tank once he gets a pellet. its as if the GT is a schizophrenic, and the Oscar is the perfect example of an intelligent fish by comparison. that's my 2 cents.
