Yeah the males can vary greatly. Ive read about instances were they bread at 375 grams but females its too risky. They cant handle the eggs, which end up becoming slugs. Un needed stress would be put on the female. More than likely she would only produce 2 eggs at that size. Id say the soonest you could breed her would be at 1200 grams. But thats just a min. Personally id wait till shes at least 1500.
