is it ok to use multiple foods in one feeding, i use there regular food which is omega one cichlid large pellets, but also i use once or twice a day brine shrimp , shrimp pellets that sink for the catfish, tubifex worms freeze dried, and every now an then some goldfish flakes the little jacks go nuts over it for some reason! just a little of each not over feeding, just for about 3-5 min of feeding time, or until they stop eating. thanx
