What is wrong with my lizard? Starting to worry

[chairman]

What are you using to provide UVB, and when was the last time the bulb was replaced?

Do you know the surface temperature of the basking spot?

Do you happen to have a couple inches of soil as substrate? Preferably covered with some leaf litter and a couple cork flats? That combination really helps create humid hideaways for lizards.

How many males are in the tank?

How large is the tank? Fence lizards are typically very territorial and very aggressive. That female could be the lowest in the pecking order, making her stressed, contributing to her issue.
