These have been good corals for me becuase my fish leave them alone! I like to group them together (they don't sting each other). I can't compete with the photos above, but will share anyway. The link is to a photoshow of my tank so you can see how they are incorporated into it. I will need to move my xenia shortly as it is growing and at night leans too close to one of the frogspawns. I have VHO's and they seem to be fine with that lighting as long as they are placed fairly high in the tank. I have found that the redder varieties take a bit lower light and are a bit easier than the green, but all have done well for me.

Here are pics of the individual kids I currently have.
