She is a she because they told me that she is a female...I spoke to the pet shop guy and he told me that they were feeding her 2 times a month...but I don't think so...for substrate I use some soil that they game me,It's a block of compress stuff and you mix it with water and there's the substrate,for heating I have some sort of heating wall...for humidity i have a bowl of water and i keep the soil underneath a hide always soaked in water...she can eat a fuzzy and now I will feed her once 5 days,but I don't know if 2 are ok...I don't want her to get sick from 2...but tell me if I should feed her 2 fuzzyes...tnx so far...
