Baby vield problems

[wofgon]

I got a female baby vield chameleon about 2 months ago. She is always on the top screen of her tank? is that normal?. She has not grown at all. I almost never see her eat. The past couple of weeks i keep seeing her pop stuck to her bottom. Any suggestions?

She is in a 20g tank
has a 40watt bulb on 1 side and a repti-glo 5.0 on other. (Today i took off the 40watt and added a repti-sun 5.0 in thinking she is not getting enough uvb)
I use repashy calcium plus as a supplement on her crickets.
I have a screen tank but i think its way to big for her i was going to wait until she was 4 or 5 inch to add her to it..(16".16".3')
Misting 2 times a day.
She has 3 fake plants and 1 real photos.. I never see her on the photos.

How warm is it in the coolest part of the cage? Where she sits most often?

Low 70's. right under were the 40watt used to be was around 78.. she moves around allot i see her sitting on different plants often. I use papertowel as a substrate so i know she hasn't eaten anything bad... She was fed a Large cricket on accident once(about a month ago).. She looked like it was chocking her. after that i havent noticed much hunting activity.

I usually keep them in the low 80's.
