I have had reef tanks for a couple years now. Dabbled with sps here and there and have been debating on going that route. Went to the LFS for a cleaner shrimp yesterday and they had a huge colony of 3 different kinds of sps that had encrusted together in a scratch and dent $25 frag section of a huge tank. I thought "this HAD to be a mistake". So I took it home. I broke apart the 3 different types. I have loosely identified the large one (roughly 7 inches long and the branches spread about 5" at the top, several branches). It is a green/purple millepora. The other smaller frags I broke off look to be acro to me. One is a deep purple with a dark green hue and the other is wicked neon green. I will try to get pics when I get home tonight. Work has recently blocked access to photobucket. Corals are now under my 20k 250w halides and coloring up!
