I still can't tell with the new picture but if it does indeed look white and fuzzy like in the picture of another fish I would treat with a fungus medication. I use Jungle fungus clear tank buddy tabs. Works well. Until you get better pictures it will be hard to diagnose. For future references you can get some aquarium safe silicone and have your local hardware store cut you some custom sized Plexiglas. You can make your own picture tank - you can do it really thin (like 2")so the betta will have a harder time swimming around when your taking pictures.
