you could also do rbtas, I have a 55 gallon with a rbta in it for 3 months now and its grown considerably and looks mighty fine, never moves from its spot and the clowns just love it. And remeber watts per
gal is only a guideline and a fairly bogus one at that since watts per gallon has nothing to do with intensity, which is what will give a lot of the more difficult corals their color (as well as clams)!
