The green tree frog is one of the most popular pet frogs in the world. This is because of its submissive behavior and long life expectancy. It is also a popular pet frog because it looks like a cartoon frog. It is also one of the easiest frogs to take care of. Their diet are not expensive. They also have a strong resistance to diseases. Overfeeding the frog is a common problem with pet owners. The green tree frog tends to become obese when it is overfed. In the wild, the frog's energy is needed for the frog to catch its prey. However, in captivity, they are given live food. They are also housed in comfortable habitats. This makes the frog lazy because it does not have to do any activities. When the frog is inactive, it will gain weight. An overweight green tree frog will have fat layers on top of the head and body. This gives it a "dumpy" look. This is why some pet owners call the green tree frog the "dumpy tree frog".
