I have two African tanks one with Mbuna and the other with Peacocks/Haps. I like to vary their foods and feed them 2X a day. Every so often I like to give them a frozen food treat. Which is good for them and which frozen foods are bad between brine shrimp, mysis shrimp, blood worms, krill etc?. Their "regular" foods are NLS and spirulina (veggie flakes)
