Angolan Pythons (Python anchietae) are the next species most like a BP but can be hard to find. and yes, BEL's, Pieds and Clowns are popular and u can't go wrong. i would also recommend a regular Banana or 2-3 gene Banana combo, Mojave or Leopard combo or nice ringer Champagne. have fun shopping and filling your 3rd tub.
