I am wondering if there is anything else I can feed my fish that will contribute to their well being. I have 2 JD's, 2 FM's, and a clown knife to feed. all are under 4 inches. I feed them bloodworms, brineshrimp, beefheart, meal worms, earthworms, and cichlid gold pellets. is there anything else that I should be feeding them to make sure they get the right nutrition?
