Definetly a pavona IMO. It will take as much light as you can give it, but should be fine anywhere in the top 12" or so of the tank. They do take a little calcium to grow, so you will want to make sure you keep up on water changes and/or Ca supplimenting if you have additional stony corals. They need some current to be happy to, but other than a little of this and a little of that they are generally a very hardy coral and very attractive to me. I like their patterns. Some of them have longer thenticles than others, but most of them I have seen are some shade of green. Best of luck!
