In captivity, C. cranwelli and C. ornata are the most popular species, [4] along with the "fantasy frog", a captive-produced hybrid between C. cranwelli and C. cornuta. These frogs can live in a terrarium with a floor area 8-10 times the size of the frog. [4] They commonly cover themselves with substrate or just sit contentedly in the water.
As suggested by their name, microhylids are mostly small frogs. Many species are below 1.5 cm (0.59 in) in length, although some species are as large as 9 cm (3.5 in). [3] They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at ...
This makes the species even more unique, as PLOS One said, because other frogs that skip the egg step typically give birth to froglets, or baby frogs, but these frogs still give birth to tadpoles.
