Breeding a mojave/lesser BEL X a Lesser or a mojave is not smart.You would be better off breeding it to another Lesser or Mojave. At least that way you would have a chance to get more BEL's.
How will you know which combo the BEL you make is?
Mojave/Lesser BEL's can look as white as a lesser/lesser combo BEL, so what do you tell the potential buyer the snake is if you can't tell.
