Thanks! I want a large school of either fish...BUT I also keep thinking about maybe getting one single fish that will grow large. I heard that large serevums are peaceful and will actually eat from your hand?!
It would help to have the tank dimensions here. Heros severus can attain 12 inches (30 cm) although 8-10 inches is basic. The fish is omnivorous but I've no idea how far this may go with regard to plants. Cichlids will substrate filter feed, and carpet plants will probably disappear.
