Thanks for the replies,

I just took a picture of her tank, it's below.

She's in a 20L tank. Two hides, one on either end with a water dish, driftwood with leaves draped over it in the center.
On the warm side, the hide is reading 92, on the cool side, 80. Humidity averages around 55. There is a dual fixture above the tank with a day and night light. Bedding is Aspen with a mix of Spagnum Moss.

Her husbandry should be just about ideal for her... She's eating well; an adult mouse every 5 days and she's shed once since we brought her home. Shed was one full piece.

I'll try what was recommended in the video and see if that helps at all. But still open to suggestions... hoping she's not going to be nippy like this constantly... that would be disappointing as my daughter loves her and loves to hold her.
