Anemone Splitting

[Pier Pressure]

I bought a small GBTA a few months ago from a fellow reefer. Dude told me that his were splitting all the time. It has tripled in size and not split at all since I added it. I bought a RBTA from Golds that is hosting a carribean crab and it moves around quite a bit and does not seem very happy. Yet I seem to have found four very small (dime-sized) babies that look red on a rock near it. I, too, would like some advice on whether or not splitting is caused by stress and thought I would add my anemone experiences as well to this thread. The RBTA does not seem to have split at all, but if it did not, then where are the babies coming from?
