Aquatic frogs live underwater. These can be completely aquatic or semi-aquatic. Aquatic frogs require aquariums. The best aquatic frogs to keep as pets are the African dwarf frog (Hymenochirus boettgeri), the African clawed frog, the western clawed frog, and the western dwarf clawed frog. The African dwarf frog is actually the Zaire dwarf-clawed frog or the Congo dwarf-clawed frog. This frog is endemic to the Democratic Republic of the Congo, Central African Republic, Equatorial Guinea, Nigeria, Gabon, and Cameroon. The African clawed frog (Xenopus laevis) is endemic to Subsaharan Africa from Sudan to South Africa. The western dwarf-clawed frog (Hymenochirus curtipes)  is endemic to the Republic of the Congo and the Democratic Republic of the Congo. The western clawed frog (Xenopus tropicalis), also called the tropical clawed frog, is endemic to West Africa and a small part of Central Africa.
