You can tell the genetics of a BEL combo. Just look under a black light and see if a pattern appears. Like a Spider BEL will have spider markings under the black light.

Anything fire/yellowbelly is a must have in a collection. It will enhance every morph you have. Also, both fire and yellowbelly have a nice looking Super. (BlackEL and Ivory)

And I agree with the clown as a recessive project. Pastel G-Stripe Clowns would probably be phenomenal. I don't think any ones done that combo yet either.

Are you into darker morphs? What about Black Pastels?
