If you havent cared for corals yet or the tank is fairly new, I would start off with leathers, mushrooms, zoos, polyp corals, kenya tree.
The hammer corals demand more light as they are LPS and also require a maturer tank.
I would start of with any of those, they are hardy and are cool looking corals. There are alot of colors within that list that you can choose from to diversify the tank.
