frogs have four webbed feet. African clawed frogs have webbed hind feet while their front feet have autonomous digits. African dwarf frogs have eyes positioned on the sides of their heads, while African clawed frogs have eyes on the tops of their heads. African clawed frogs have curved, flat snouts. The snout of an African dwarf frog is pointed. African dwarf frogs are very active and rarely sit still for any period of time. When stationary, the African dwarf frog has been known to float in one spot, with its limbs completely outstretched, on the surface of the water. This is normal behavior, called "burbling". Sometimes they just float with limbs spread out, drifting on the surface. African dwarf frogs are generally peaceful with animals of their own size, but their diet sometimes include smaller animals. Fish are known to eat the eggs of these frogs. African dwarf frogs spend most of their time near the bottom of the water, where they feel safe from predators. Most frogs sleep up to 12 hours a day, provided no threat of predators is present. These frogs are suggested to be kept in a group of two or more due to their social nature. Despite being fully aquatic, the African dwarf frog still needs to be able to reach the surface to breathe. These amphibians are not great swimmers, so water currents should be kept low and deep tanks may pose a challenge to their ability to breathe. In the wild, the Congo forest floods yearly to a depth of 24 inches or more, so any depth less than that will be suitable. They also should be kept in an enclosure with a secure cover to prevent escape and plenty of hiding spaces as in the wild they tend to be prey to a variety of animals and open spaces cause skittish behavior. The frogs eat any smaller fish. The optimum water temperature is 75–82 °F. The pH of the water should be maintained between 6.5 and 7.5. These frogs cannot survive out of water for longer than 20 minutes in low humidity, as they dry out. Because they are fragile animals, care should be taken when handling African dwarf frogs, especially when considering them as a pet for young children. These frogs should only be held outside the tank max of 5-10 minutes, but it is better not to, for the safety
