some people say its okay around 7 months for these guys, but after watching Asha give birth and how frail she was for a while after, I don't think I'd subject them to breeding until they're stable and older. Shes only starting to put the weight back on now. I'd maybe separate your male and female at like 5 months to make sure they don't breed (if they aren't already separated?), because as soon as the male reaches maturity, he will start harassing her.
