you might want to watch the new clown. he might be fighting with the older one. That could be why hes hanging out in the back.

I agree with boozzbro,
The most likely cause is that one of the clowns is attempting(succesfully) to show her dominance. It's one of the fascinating, yet frustrating aspects of having more than 1 clown in a tank.
I would suggest that you keep a close eye on both clowns and as a precaution, add some garlic to their meals to help minimize some of the inevitable stress.
Keep us posted on how they are doing.
