I did a quick count and I really don't know the male female ratio but I have about 90 asf's from pinks to about 40 breeding size.
I feed mine to everyone except a boa and adult Hog Island. They can and will fight till the end and don't like to feed multiples, so I prefer rats for the big guys but may I have to change that in a feeding or 2.
The only reason I started to begin with was because they do have a lot less smell and is very tolerable compared to norway's.
