I have a longnose gar(named jerry) and 2 oscars, I feed the oscars a large variety of food but try to stay away from feeder fish but the only thing jerry eats is live feeders. when I put a feeder in the tank for him the oscars will try to eat them if jerry doesnt get to it quick enough are there any suggestions you guys have on feeding my gar so my oscars wont take his food?
