Jay, I know they have to be at least 6 years old to breed and perhaps older. Also similar to lizards they can't be moved from cage to cage. I once bought a pair in the 80's and gave them to Don Hamper on a breeding loan and I think it took 4-5 years to breed them and they were about 5' long when I bought them...thanks
