Bubbletips are the safest bet, but it is always a toss of the coin. I have two unrelated RBTAs that are right next to eachother that have never moved once they grabbed on. I have even moved their rock all around the tank and they haven't done anything other than shift a bit. I hope I am not jinxing myself because I have a heck of a lot of coral in the tank that they could annihilate!
