How too Get my Clowns to host

[halwake]

Bought 2 small clowns and an RBTA to add to our existing tank that had 1 slightly bigger clown in it. Put the anemone in first and then the new small clowns and they immediatly went straight for it. After a few days the original clown started hanging around in it and chased the others away. Sadly that anemone did not make it but we bought a new neon pink and speckled bubble tip and they paid no interest for the week it was in the tank. I came home last night and one of the small clown was curled up sleeping in. Now they are all interested again. Who knows...
