The pea puffer, also known as the dwarf puffer, is a small freshwater fish belonging to the Tetraodontidae family. It is one of the smallest pufferfish species, reaching a maximum size of only about 1 inch (2.5 cm) in length. The pea puffer is known for its adorable appearance and playful behavior, and it is a popular choice for hobbyists who keep planted aquariums.
Pea puffers are native to the shallow, slow-moving waters of India, Bangladesh, and Pakistan. They are typically found in densely vegetated areas such as rice paddies, ponds, and small streams. In captivity, they can thrive in a well-planted aquarium with plenty of hiding places.
One unique aspect of the pea puffer is its diet. Unlike many other freshwater fish, pea puffers are carnivorous and require a diet that is high in protein. They are known for their preference for snails and can help control populations of pest snails in the aquarium. However, it is important to supplement their diet with other sources of protein such as frozen or live foods.
Overall, pea puffers are an interesting and entertaining addition to a small, well-planted aquarium. They are relatively hardy and can be kept with other peaceful species as long as their dietary needs are met.
