I have 3 sevs, 2 gold and one green, They eat rosies, bloodworms, nightcrawlers, krill, Hikari Bio gold, Hikari Gold, Hikari staple (which has more greens in it) Wardley cichlid crumbs, Spirulina flakes, plankton, Mysis, spirulina brine shrimp, Ocean Nutrition Formula one...etc. I used to have duck weed, and various Hygrophilia, but they pretty much munched those away. I have no more duckweed now, and just a few shoots of Hygro. They graze constantly. And as for eating out of my hands, I hope they don't try to eat them. Of all my SA cichlids, only my Green Terror won't eat out of my hands. My pike, severums, angels all have ate out of my hands since the 3rd day I had them.
