Um well id make sure that the new clown fish is not as funny as the old one, because the old one might kick his butt if he is. Also id make sure that the old clowns material is copyrighted, that way if the fish do hate each other, the new one wont take the old ones jokes. make sure that the new clown fish does not all hog all the material such as clown shoes, make up, rubber noses, etc. if you dont that might end up bad..............thats all i got. good luck
