out of the three you listed id go with a whites. off list i'd say my bummblebee toads are funny and quit enjoyable to watch and easy to care for and breed. the bummblebee dart frogs are very outgoing and aren't shy, also they have a very nice call. learn about all and see which would be best for you. some people don't like messing with the smaller species cuz of fruit flies and other tiny feeders. the tank type or orientation will be different for a non-aboreal species vs. an aboreal one.
