i know exactly what you are talking about. i have a book with them in it. "popular amphibians" by the herpetocultural library. they grow up to one inch long. the enclosure can be relatively small but a 10g would do best with about 4 inches of water and some land they will thrive. feed small(1-2week old) crickets or even fruit flies, you can also feed sm guppies, and blackworms if you place them at the water's edge. it sounds like you could try prepared pellets for ease, but the book doesnt say anything about that. i would think it would be worth trying a floating pellet small enough for them to eat. i have seen them in pet shops i worked at but never had one personally. if you have any other qs just post them.
