Yes - but try as much as you can to entice him into eating a worm or 2 first.

If you want to try the bath, use the plain clear flavor. Make a small bath by mixing 1 cap of Pedialyte to 10 caps of clean TREATED water. Let him soak for no more than 2 hrs, then return him to his small container with fresh treated water.
Monitor him a bit while in the bath.
