I have two juvinelle hippo tangs. They used tow hang out with the clowns and play.
When a ritteri came into the tank they were in timeout in the overflow for 24hours (self inflected time out). When they came back they went to hang out with the clowns that were already in the anemone.
The Clowns darted toward them and pushed them away nicely. Not the normal dash and smash. Yesterday they were playing like always. Again. though, when the clowns went back into the anemone they were followed. The clowns pushed away their friends, like they knew what would happen.
