Crystal, what a lot of dart frog breeders/keepers do is put a tadpole in something like a small Tuperware/Rubbermaid/Zip-loc container with a little bit of water. When the tadpole begins to develope legs, they drain off some of the water and tilt it a little bit to form a little bit of a slope or beach. Often some sort of aquarium plant is used to help the froglet to climb out.
