I had 2 RBTA in my tank and a mated pair of Ocellaris. After 3 years they never bonded. The clowns actually host my giant clam. The RBTA were sent packing. I got tired of them stinging my SPS. I tried everything to get them to host (my clowns). I put a clown shaped lettuce clip next to the RBTA the clowns would knock it away but would not host, I taped pictures of clowns hosting in a RTBA they would show aggression toward the picture but would not host. For feeding the RBTA I would just take a silver side and thaw it out in a cup of tank water then I would wave it in front of the RBTA and just place it on the tentacles the RBTA would do the rest.
