I'll put a link below to The Sweet Spot (glider medical forum) - the Glider Gourmet section. There is a great article on the importance of diet and also articles on several of the more widely accepted glider diets. You can take a look and see which works best for you and your gliders. I personally feed Val's Green Variety Diet and love it.
While you are at TSS, take a look around. It's a medical forum and the place you can go to when/if something comes up to see if others have had the same issue and what was done (worked, didn't work, etc). It's just a good forum to be familiar with.
Enjoy!!
