Hello from Kentucky

Small world!

 

Or get a bigger one ........*&%&*^$^%@ I meant to say smaller, my bad!

You could also try this. Get the smaller clown and another species of fish as well to keep your larger clown occupied with its aggression.

 

Do you have any rock in the tank? Places for the fish to hide if need be?

Wow, clowns can be extremely aggressive when they breed. You don't want to put 2 different kinds together and like was mentioned above 2 females. The females are the most aggressive of the 2. Good luck on the pair. I have a breeding pair who are very territorial and who have successfully destroyed a sea anenome by nipping and slamming it to death. I have had success with some bablies but that is a full time job. Getting the smallest one possible or starting another tank would be the best options I think. Wait to see what the others have to say.
