Zoanthids, mushrooms, softies like xenia and leathers.
Are you looking more for LPS corals? Blastos are fast-growing LPS corals, as are torches, frogspawns and hammers. Bubble corals, too. But they are still much slower than softies.
Green star polyp is one of my favorites. It forms encrusting mats of really nice looking, feathery corals. It can be a bit invasive, but I think it gives a tank a nice, developed look. I've got a neon green variety that I sell back to the store all the time since it grows so fast.
i only have about 220 watts on my 75 g. one blue 6500k one actinic and 2 10,000k bulbs. im interested in pretty much anything that can stand those parameters. probably leathers and things to start. ive got alot of flow so i was considering some gorgonias
