David, . Most of my female BRBs are larger than the males. They seem to grow at about the same rate for the first two years but after that the males are actually more active and less apt to eat than the females. By the time they are 5 years old the females are usually 6 to 6.5 feet long and the males are 5.5 to 6 feet long. Most of my older male BRBs stay more slender than the females. Jeff
:I'm planning to keep a Brazilian Rainbow Boa and was wondering how much longer and heavier females get than the males?
:I've also read that female BRBs are more active than the males. Is this what you all have observed as well?
