If he's eating, try feeding him a small piece of thawed, deshelled frozen pea if you have it (I microwave mine for a couple of minutes, take the skin off, break off a small piece or two and feed it to my betta). I also wouldn't feed him anything for a couple of days and see if he improves.
He's not eating at all. I will try a frozen pea.
