I've tried many things to get my pair of ocellaris to host in an RBTA. Tried to spot feed around the nem, bought another RBTA to see if it had a preference, and even the picture on the window.
I'm not advocating what I did, but I had to temporarily house a pair of juvenile black ocellaris that were hosting and rbta for my brother. I had them quarantined in a floating breeder to make sure my clowns wouldn't attack. After I was sure they didn't care about them, I released them into the tank. My female watched them for awhile and then finally jumped in with them. It really was monkey see, monkey do.
I just need the male to join in now. Here's a pic of them.
