Brazilian Rainbow Boa concern - help

[smg1169]

Hello everyone. New here.

I have a Brazilian Rainbow Boa who is almost 20 years old. I've never had problems with her shedding before. She has been in her water dish for over two weeks - rarely coming out, maybe at night when I can't see.

I had the vet check her two weeks ago and she said she looked good and healthy. But she has been in her water for too long. She is white and ready to shed but hasn't come out. She looks dead and I keep checking on her.

We have recently moved from AR to OK and she has fed and shed just fine over the last 4 months since the move.

I currently have a new hood with fluorescent and incandescent lighting.

Help - too long in the water and hasn't shed yet!
