Introduced a green BTA to my tank within the last week and he has been cruising around the tank looking for a home. My 2 clowns have been following the BTA and nesting constantly whenever he stopped. 2 days ago he found a home at the bottom of a rock in a hole in the rock. He has been looking great the past 2 days there and all of a sudden he sucked all the way into the hole. 2 questions should I be worried and is it possible he just wants a break from the clowns? Thanks in advance for any advice.
