We added are 3 anthias to the main tank about 2 hrs ago. They have been fine with all of the other fish, and no fish has bugged them at all. However 2 of my anthias are out in the open swimming around together as happy as can be, while the 3rd one is hiding under a rock

I tried to tell her to go find her friends however she's not listening

*Update* Yippee! the 3rd one is now out and swimming with her friends.
