Do you have a wet box for her ?
Its a box with a hole in it filled with moss, I use old butter boxes or tupper ware... - they need it to diggest and when they get ready to shed - my older ones are often more then 5 days in this wet boxes...
when its ready to shed, they need a higher humidity and because they don't see that many when they are blue, they don't move
no worry please, but don't 'overload' your small tank, this can be to much for them, also they love to dig,... maybe another ground... aspen or something similar ?
