Hex tanks are not good for reef tanks because of the height. You do not have enough lighting to add any anemones. You should probably get a pendant metal halide if you want any inverts.
I agree with the lighting, definitely not enough. You can upgrade to a nice metal halide fixture for about $250. This could support all types of corals as far as lighting goes, anemones, and clams.
Inverts are fine with what you have but I definately would go to a 150-250w MH pendant light fixture. Only thing I dislike about the hex tanks is they rob you of actual swimming space.
