Hikari Gold is a good staple. Currently I'm using Hikari Gold, and Omega 1 Cichlid pellets. I just ordered Kens Premium Floating/Sinking Cichlid Pellets 1.5mm and Kens Premium 1.5 mm Slow Sinking Growth Pellets, from Ken's Fish. I haven't tried them before, but I've heard good things, and the price is Great. New Life Spectrum is also excellent, but a little pricey if you have allot of mouths to feed.
