I had one of the same RBTA's. Eventually, I ended up with 6. After the first split, the others happened much sooner. They actually become pests by their large size and the fact that they sting all the other corals in your tank. They are hard to get rid of because their feet embed so deeply in some of the live rock. I eventually managed to remove 2 and traded them in. One walked into a Vortec pump which I did not mind. I still have 3 and can't wait to get rid of 2 more. They are pretty but I just wish that they were not so detrimental to all the other corals in my tank.
