It was one colony and now it is two. It split itself. I just wanted it to split onto a separate rock and then have the mother colony on the original rock. Then I could move the new colony somewhere else in the tank.
When this one split, not only did the new piece attach to the new rock frag
but the mother colony moved itself to the new rock frag
. Instead of 2 xenia colonies on separate rocks, I have 2 on the same rock frag
This xenia is the pulsing variety. I have had it for about 2 months. I have another colony that has never pumped and has never split or moved. Go figure.
