Yes, they are just "regular" BCC. I agree completely with Daybreaker. Guyanans are BCC and there are no known morphs among pure Guyanans. There are some albino Surinams, but those were originally crossed with BCI so even they aren't 100% pure.
BUT you should be proud to have 100% pure Guyanans! These snakes are highly prized - especially with the nice aberrancies in pattern that your male shows. They should throw some nice offspring.
I would pay attention to that previous advice about feeding though and they are less forgiving of husbandry errors than BCI are. Feed smaller prey less often and keep a careful eye on temps and humidity.![]()
