Don't kid yourself with dumerils. They are awesome snakes, but they are BIG!!! Especially if you are used to BPs.

Males often top 7'.. females can get up to 9'. My female is 7'4" and 21 lbs.

Here is a pic of my dum with a 1' ruler.



BRB stay much smaller than BCI or dumerils. They require very precise husbandry however.. too high temps or low humidity will kill them.

This is my hogg island boa. She will most likely grow more.
