You aren’t wrong- he isn’t well.

There’s an article on fish depression here: www.nytimes.com/2017/10/16/science/depressed-fish.amp.html

did you change the filter or media w/the move? Was he in the same tank before/after the move?
is it possible toxic pockets in the substrate were exposed in the move?
What do you usually feed him and on what schedule?
is he somewhere he can see his reflection-which would cause him to hurt himself?
Is it possible he was exposed in the move to anything out of the ordinary for him?
Do you have Live plants? They can help increase dissolved oxygen and help buffer the flow from the filter so it isn’t too strong.

10gallons is at least a decent size but it could still be a little small, even for a Beta as the minimum recommended size for a betta is 5gallons to start.
No one wants to live in a closet. You can survive there, but it’s hard to be happy. Frequent water changes (a really clean closet), doesn’t make up for it.

I saw this was unanswered so I hope this helps.
Maybe someone with more knowledge on bettas could give more specific information without all the links. Good luck, hope he makes it.
