hrm, I use several types of food for my cichlids...
everyday food
frozen spirulina algae cube, ocean nutrition
spirulina flakes, ocean nutrition
shrimp pellets
algae wafers
as treats (usually one of these a day at some time)
brine shrimp
krill
mysis shrimp
shrimp, pieces that i feed to my anemone, they get the scraps
anyways, they all swarm anything I feed.. they especially love the shrimp.. its just regular shrimp from the store, which is always followed up by spirulina flakes to help them digest it.
i find that variety is the spice of life, especially for cichlids. they all are brightly colored, very healthy looking, and I have fry on the way from 3 of them..
