Right basically ive had her about 3 months, and she hasnt eaten a thing in about the last month, but shes just getting fatter and fatter, and as far as i know (not very far) but she was sold to me adult, but im not sure how to tell the age of a flatrock, it could just be a molt but i dunno.

Heres a pic anyway, if its a molt then my bad lol:

I'd say adult and possibly pregnant female.

yeah she might be pregnant or she could just be fasting, ive had a flat rock female for about 18 months and shes only fed about 3 times in that time nad thats only cause i had to kill the crickets for her and place htem in her hide, but she wont lose any weight, their weird animals

looks preggers

Ok thanks, well i hope she is pregnant cause should be intresting.

Question: From when they mate how long does it take for birth?

Gestation for this species can exceed two years, and because they're so slow-growing, a three month fast for them is like the time between lunch and afternoon tea for humans.

I would need a size comparison before I would say yay or nay to an impending mold, and even then, being pudgy isn't really a sign of anything.
