My Pom-Pom Xenia that I acquired a week ago appears to be doing well. It pulses like crazy now and it is growing. It's taller now than it was a week ago. I purchased it on a small shell. When I put it in my tank I put a rock on the shell to hold it in place. The coral's foot has now stretched and is grasping both the shell and now the rock. Hopefully it continues to do well. I would love to have a rock covered with these pulsing polyps. Some people who have these say they get out of control and start to take over the tank. Hopefully I'll be able to prune the coral and sell the frags back to the LFS so I can start to make some profit.
Enjoy the video. It shows the coral at its true speed.
