This a tuff discussion because some people believe in feeding a full pellet diet and some frozen/fresh or 50/50.
For me personally i feed a huge variety of foods. Different pellets, hikari freeze dried krill, frozen shrimp and tilapia. I even mix it up and stuff shrimp with pellets etc. Imo cichla are thin in the wild so i never feed until thier 100% full which pellets imo tend to do due to the fillers. But some even feed treated feeders which i will be doing soon. Basically a wide variety of foods is better imo.
