I have bred (or at least tried) a few young males. Most of the time, they hid in the corner. From my observations, there is an intimidation factor. In the wild, IMHO, I suspect females breed with the largest, strongest males. While smaller hatchlings will rarely breed. I have an adult albino male that is a great breeder. He had no interest in breeding until he reached the 1000 gram mark even though he was producing sperm as early as 600 grams. His first two years of breeding - from 650 grams to just under 1000 grams, he sired nothing.
