Getting there
Hatchling to adult in 18 to 24 months
Quick to a small adult size, so the housing question is settled early.
Clear sexual dimorphism
Females are substantially larger than males, more so than in corn snakes.
What that size means in practice
A 30 by 12 by 12 inch enclosure for an adult
The commonly published minimum, reflecting one of the smaller colubrids kept. Depth of substrate matters too, since they are enthusiastic burrowers.
Smaller than a corn snake or ball python
Which is much of their appeal for keepers with limited space, and why mouse-sized prey suits them for life.
