Q: 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.
Can we conclude that can african dwarf frogs survive out of water?
OPTIONS:
- no
- yes
A:
yes
