All corals are aggressive in some way shape or form. Zoas don't really have a strong sting but they excrete toxins in the water and be careful when you handle them make sure you wash your hands afterwards. You can have LPS with that light something like a ducan (which needs to be fed at least once a week) they are very pretty and adds a lot to the tank. A toadstool is another thing that would do great under your light and is easy. They have a slimy toxin that bothers other corals. Kenya tree is nice and easy some people have problems with them dropping branches but mine never does. They just get huge in my tank and I have to frag them.
