I have no rift lake cichlids in any of my tanks. ?, I dropped all of my haps and peacocks off at the lfs today. Time to try something else. ?
If beside rocks, you mean plants..... most circular, flat shaped South or Central American cichlids are primarily vegetarian.
Sevs, Uaru, Vieja, Cincilichthys, and even many Herichthines are either partially or predominantly plant eaters, and some will gobble down bitter plants even Africans don't like.
Any cichlid that resembles the body, and mouth shape, and colors of the Asian cichlids below, tells you, in nature it favors a lot of leafy food.

You should take that post with a grain of salt. It's been explained in painful detail more times then I can count.While I agree that many of the South American species listed above work with severums, I disagree with many on the list of what is said to work, and although many severum are aquarium strain and superficiously adapted, they originally are evolved to live in soft, less than nuetral pH waters. While many of the Centrals listed come from high pH, hard waters of Central America,and Mexico.
And the aggression level of many of those Centrals is much more heightened and territorial than their South American cousins.
And although you may not experience problems right away, down the road, health issues often show up as HLLE and other water parameter stress problems.
