Mine will go to the corner of the tank, and the bigger of the 2 will push the smaller one up and down the corner wall while the little one is sleeping. Almost like a game.
Once they are both asleep they basically lay on top of each other in the corner with very little wobble movement.
In the day, If I come within 3ft of the tank, the 2 clowns will follow me around thinking I am going to feed them. It's funny when I'm trying to look at something up close, the clowns will swim right in my face as if to say "Look At Me!, I'm Here!"
