I've heard of this happening... some better prefer smaller tanks over the larger one(this doesn't apply to everyone, but I have heard of some cases where it does).
Does he have a heater in his tank? Sometimes extra heat can help aid some bettas that aren't doing too well.
Good luck with your boy! I hope he begins to feel better. =)
