are u looking for 1 female for them to share for different years/seasons? or 2 separate females?
first, get what u like, what u think is pretty and what u want to produce.
1. I would get a multi-gene girl. I would recommended a Leopard combo, maybe one within the BEL complex of o work with your Mojo boy. u can possibly make a white snake, a purple snake or one with Koop stripes and patterns.
2. I would recommend a Black Pastel or Cinny combo, to produce some Supers and many other stuff with your Black Widow or other cool combos with your MoJo boy. (just be prepared for birth defect issues is u wanna go this route.)
3. Recessives - Pieds and Albinos - also great options but takes more time, more generations. Mojo Pieds, Pastel Pieds, Black Pastel Pieds, Spieds, etc. etc. all look great.
there are endless possibilities with BP's. good luck and have fun.
