You mean Eryx Johnii? Also called Indian Sand boa
I breed them, and would be happy to answer any questions.
They are easy to keep and the largest sand boa.
There are completely brown ones(as adults), which is what is normally seen, but there is now a new selectively bred line that retains the juvenille orange color right into adulthood.

above the normal brown phase(my gravid female last year)

A new born baby from above female (they're big)
