I would not leave food in the enclosure all the time. You're inviting a mold or mite problem. Leave some pre-killed food twice a week and remove whatever is uneaten after 24 hours.Heh what can I say... I like big butts and I can not lie
In my defence though, although I've made sure there's fresh pre-killed food in her enclosure all the time, I don't think she's really grown like this recently. Pretty much the size I got her in from the dealer I believe, give or take.
