it is not certain, my ocellaris went striaght into my BTA, but sometimes they refuse to host BTA's, just a chance, i would say more often than not they will host it.
I have 2 ocellaris clowns and I added a bta and neither will go near it. Could be because they are tank bred? I have heard that tank bred clowns are harder to get to host.....though both of mine host in my frogspawn and my candycane coral......go figure
