For the most part, sugar gliders get a large portion of their fluid intake from fresh fruit and vegetables, and along with the staple while getting nutrients. If you switched to mostly dried, they would drink more water and lose out on needed nutrients found in the fresh fruit and vegetables. Some dried fruit can be offered as a treat if they enjoy them. Personally, I strongly don't recommend offering more dried than fresh.
BTW, my oldest girl is named Lulu also. Lol.
