Well I got my first female at around 150 grams or so? Not exactly sure but somewhere around there, and by the end of the year she was 1000 grams about. Some grow faster then others. The female I'm talking about has never missed a meal yet. I would also feed her multiple prey items occasionally. I wouldn't recommend doing this all the time. I would do a couple time a month if that, and I would use a smaller prey item rather then two normal size.
