Depending on the depth of the tank, there is actually quite a few things that you can keep under normal output lights. Heck, we're keeping Green Star Polyps, Zoanthids, Mushrooms, Xenia, and a Long Polyped Toadstool under (2) 48" Normal Output T8's in the tank at Kyoto until we can get better lights. Beyond what was mentioned above, things like Kenya Tree, Colt Corals, and carefully positioned Euphyillia (Hammer, Frogspawn, etc) and Candy Canes will even do fine.
