nice collection. u need to post some pix of your animals.anyways u have a solid base.
i would get something that really compliments the Leopard gene. (BTW do u really have a VPI Axanthic Leopard het Pied? pix plz) i see u like Pieds, but i'm not the biggest Leopard Pied fan as Leopard can be hard to ID in Pieds esp. the higher white ones. if still wanna go that route, i would get at least a double het. anyways what i would get if i were u would be a Spotnose double het VPI Ax and het Pied or het Clown.
my friend has an Axanthic Coral Glow/Banana. she got one of the first ones and he's in his first year of breeding. anyways they're pretty kool and kinda look like Lavender Snow's.
