Not sure what Rykna means. Most Corals contain zooanthella algae. It is what colors the corals. It is the amount of the zoo. algae that anemones are dependent on that makes them need more light. As far as needing MH explicitly, not true. All kinds of anemones have been grown under T5s, VHOs and PCs. With T5s about 5WPG should be sufficient, but with PCs and VHOs I would do no less than about 6-7WPG. The thing with fluorescents is that you do not get the penetration you do from MHs therefore the best placement would be mid to high in the tank.
