Do some research into anemones, they are an expert only animal and most get huge, need metal halide lighting, feeding, and perfect water conditions. The only anemone I would recommend for a tank that size would be a rock anemone and even then you would need at least power compacts. Even low light corals like mushrooms will die under your lighting, I've seen it happen. Please don't take advice from this person ever again and keep in mind that most animals in saltwater are taken from the ocean for you and aren't replaceable, you should be concerned about that and not your $15, IMO.
