My girl is pacing and clawing at her tank doors. Tank is 6x2x2. This is the third day and Im concerned for her. No changes to temps or decorations or food habits.. This is a completely random occurance.
Does your beardie get time to run around outside of her tank at all? Glass dancing is usually a sign of stress but sometimes they do it when they have pent up energy or are bored and want to explore.
Try putting her in a room that you've secured by covering areas she can get trapped in, removing small bits from the floor that she could ingest, remove access to any other animals, and supervising her closely. You can set up a portable basking lamp in the room if she likes roaming around. They also often like to sit on a window sill and look outside.
If you don't have a room that can be easily made beardie-proof I find that those foam puzzle piece mats for kids are pretty useful to make a little fenced in area with, or you can use them to block off places she could get stuck in/crawl under.
