They will need more intense lighting that shrroms and zoos would need. I kept some acroporas and montiporas under T5s w/ IceCap 660 ballast (and saw growth) in a 20g tank. I personally would recommend going with the best lighting set-up that you can possibly afford. There's nothing quite as frustrating as buying equipment and then deciding that you "need" to upgrade a few months later. Save your money and get the best up front!
