If i may id still like to see , im in no way trying to shame you or be condescending, it just looked a little weird to me, my beardy has had tail rot from a nip so i know what it looks like,... my beardy was shedding her tail for like a month , sometimes it takes a while especially if its colder in ur state.
Thats stress, in babies their bellies will look like cheta print and their tails get dark grey, do you have backgrounds in ur tank? He could be seeing his reflection and thinking someone is in there with him.
Her tail does look perfectly healed, it was just the lighting in the last pic i guess, and you do have multiple hides and a blankie thats good. do you ever offer her outside sunshine? Its recommend (If ur able) i understand If u live in a big city or something. if theres any new symptoms make a post, you might want to review how old your bulbs are , ive gotten brand new bulbs and have the uvb not work.
If it’s below 50 I wouldn’t , i dont let my girl outside when it gets cold, she gets so mad and runs around the house and gives everyone stink eye.
