My males are around 1100 grams at 2 yrs old, I have had a 1900 gram boy and have heard of way larger, but it's not the "norm".
I hatched 5 yellow belly girls Aug. 8th and the smaller girl eats once a week
50 gram rats and she is 450 grams.
The largest girl is about 680 grams empty and eats 100 gram rats with 35-40 gram weanlings as mid-week snacks, and is growing super FAST.
Size and weights are so variable even amongst sibs.
