Extreme corals.
I think it is worth getting a colony of: Strawberry shortcake, Secale, validia, cerealis, tenuis, echinata if you want to spend th money, as well as many more but I have had good success with those species.
Personally prefer divers den, they hold corals longer and are generally in better health, as well as divers den gives you a 2 week guarantee, or should I now call them Petco.
It really is quite difficult to find a wild colony that will hold color and look as good a commonly distributed frags. They are also hard to mount. They are also much more difficult to succeed and grow in a aquarium, can be done but harder. In general it is easier to grow maricultured corals and get a colorful one.
