Well, You may be sorry! Now when you move him back, the major aggressor, the damsel, will have taken over and again you will have major battles. My clowns have a huge finger coral they call their own, and all the fish stay clear of that coral. It took them 3 years to choose one, but that is their major territory. I wish you luck 'cause that is what you will need. Clarkii's are the least aggressive of the clowns. Tomato one of the most, so there will be battling. Should have listened to Bang Guy!
