It seems that no matter any attempt I make, my oscars end up eating most of the food I drop in for my pictus. It doesn't matter is I drop in pellets, or bloodworms, it's all the same. Right when I drop in food for the pictus, the oscars gobble it all up, and by the time the pictus realize there is food in the tank, and they start their frenzy, the food will be mostly gone...any suggestions?
