The pictures aren't showing. I had a snake with white growths on it, also. It ended up being a fungus. I was told to soak her in iodine mixed with water. Just enough iodine to make the water slightly tinted, but not to let her head go under at all.

Try feeding the snake night crawlers or feeder guppies or silversides. You can scent pinky mice with them once you find which food he likes.
