They live in water with a pH between 7.0 and 7.6 and a temperature between 74-78° F. They can also be kept in aquariums with temperature ranges below 74 and maintain filtration of the aquarium.
Puffer fish are present mainly from South America, Southeast Asia, and Africa. They are primarily found in the submerged plants along the riverside.
There are at least about 150 known species of puffer. Some common species are,
