My coworker and friend just brought home an Asian box turtle. Naturally, it developed an eye infection which is being treated for. But recently he sent me this video of his turtle in the bath tube doing this weird thing with her mouth. My coworker says she does this all the time and he wants to know if it's a medically serious issue.

Forgive me, I'm not super savvy with box turtle care and conditions.
