Thanks for the help! Since my first post, things are much better. I reaaranged the terrarium (coco husk over clay balls, living plants, etc). Shedding time is regular now (couple of hours), she is wandering around most of the time, basking under the new spotlight (I kept the heat mat to keep humidity levels higher). Eating is normal, 5-6 smaller crickets a week (I never see her eat, but the crickets dissapear slowly

), and loves eating the fruit mix off my fingers

. And she is definitely a she. Oh, and her size is now 8,3 centimeters (about 3 1/8 inches).
Thanks for the help again!
