i feed:
freeze-dried krill (switching to frozen next week)
omega one of all varieties (super color sinking cichlid pellets, super veggie kelp pellets, kelp flakes, shrimp pellets (i call them shrimp bombs!), regular sinking cichlid pellets (i always go sinking because floating pellets can make those voracious little dudes gulp in air and damage their swim bladders)
i also regularly alternate the following frozen food:
blood words/glass worms
emerald entre -(kelp, plankton, brine shrimp, spirulina
spirulina/brine shrimp mix
beefheart (NEVER give beefheart to my africans, not ever, and they usually just get the veggie stuff - and only the frozen stuff mixed with the veggies, the SA/CA guys get more protein)
omega one seaweed sheets
i have other foods, but this is the main stuff. varied diet is very very important, but you want to see WHOLE salmon, krill, whitefish, whatever NOT FISH MEAL. you want to see salmon near the top of ingredients for color - also krill is bomb for color. you can't go wrong. i don't use hikari. it's my understanding that they use meal - someone correct me if i'm wrong.
i've heard NLS is the best food you can buy, but i can't find it and i'm very happy with omega one, so i see no reason to switch.
stay away from ****ing tetramin ****flakes. ^_^
