Ever heard of polymer gel cubes? They can be bought at home depot. They are better to use because they dont develop bacteria, and can just be re-wetted when it starts to dry. Im currently using Dino Fuel for food, will be switching to cricket crack unless there is something specifically made for frogs. I try to stay away from fresh foods and just use the cricket food so it doesnt interfere with what theyre gut loaded with.
