i feed mine Tetra colour bits, Tetra floating sticks, HBH Cichlid attack, and Hikari Cichlid Gold all as a staple, alternating or mixing them all, im also going to get some life spectrum cichlid stuff.
But once or twice a week i feed frozen(about 3 cubes for my 12 fish)
-brine shimp(most)
-beef heart
-marine diet
-mysis shrimp
-krill <- not huge fans
-plankton
-veggie
and Algae wafers(for the dudoisi), in adition to that i once a month get them(12 of them) about 40-50 ghost shrimp, but i dont feed the day before of after, thats alot if shrimp per fish.
Its important to varry thair diet, i hope this helps.
