As far as softies go, one of my mainstays for the tank is a bright yellow ( sometime described as bannana color ) sacrophyton elegance coral. There are lots of them around but hold out for a really nice bright yellow one. Usually there gonna cost ya for a really nice one but IMO it's worth it. Unfortunately they don't frag well or I'd give you a piece of mine. I'm also partial the devils hand corals too but can't get in near as flashy of a color.
Neon green nepthia is also must have IMO: Church tank has a large tank raised one your welcome to a piece of. Awesome neon green color under VHOs.
Also, there are some pretty cool clove polyps coloration out there. Some can be pricey but if unique enough, later down the road can easily get your money back in frags.
