I think that the Euphyllia sp. is one of the best to have. Most have such a fluid motion in the water, would sugest this sp. to any and everyone with a want for LPS corals. This one was in bad shape when I bought it, and knew I was going in for a challenge to try and save it. So far so good, lost a couple of the heads but I thing I have now won the battle. I is in great shape, and looks happy. Got lucky this time!
