they dont differ in apperanace, only the ultramel is a different type of caramel, it is just what different breeders have established as their own lines, i have a bell line caramel male and a nerd line het female. better to outcross caramels to help in reducing kinking and problems with babys, my adult breeder male has a tail kink and the female is fine,and all the babys that have been produced have been perfect
