Honestly, I not 100% sure how old she is, because the Pet store didn't keep track of that. I'm guessing that she's less than a year old, Maybe? I do know that she is pretty much full grown. I've had her for about 6 months now. The cricket's that I feed her are the large ones, about half an inch. They're a bit bigger than the space between her eyes. When I fed her she becomes very active and will hop all over the place, usually ignoring the second cricket. I know the humidity is kind of low but no matter what I do it won't go above 60% I've tried putting moss in but it became super saturated all the time and became super gross. I have two water dishes in the tank incase she ever feels like she needs to get wet. I also know that they can spend a lot of time sitting, but when she sits in one spot for two days without appearing as if she moved at all, I can't help but feel a bit worried.
