Zoas, palys, pulsing Xenia (but watch it doesn't take over) these are a few I can think of. Only thing to keep in mind is that each "category" of corals have their own demands, and some have opposing demands. LPS
need mid-heavy lighting, good flow, and slightly nutrient rich water, where as SPS
require high flow, high light, and pristine water. I'd recommend just starting out with some cheapie common corals and go from there. Oh and don't buy entire colonies... That's just more money wasted if they die during "training"
