i enjoy keeping new world cichlids. everything ive read always says to use a good quality pellet as the staple for the diet (i use nls). the thing ive noticed is that when i feed frozen foods only, (bloodworms, krill, brine, and beefheart) this ferocious appetite comes alive and the fish devour 3-5 times more frozen than they would eat of pellets. i forget the percentage that i read, but something said that juvenile cichlids keep a certain percent of what they eat as direct bulk. so for growing fish fast the obvious choice is frozen foods. imo.
