Pea puffer, also known as dwarf puffer, is a small freshwater fish species native to India, Pakistan, and Bangladesh. They are a popular choice for aquarists due to their unique appearance and interesting behavior. Pea puffers are small in size, growing up to an inch in length, and have a round, stocky body. They have a greenish-brown or yellowish-brown coloration with a distinctive dark spot on each side of their body. Pea puffers are carnivorous and feed primarily on snails and other small invertebrates, making them an excellent choice for controlling pest snail populations in the aquarium. They require a well-planted aquarium with plenty of hiding places and a slow water flow. Pea puffers can be aggressive towards other fish, so they are best kept in a species-only tank or with other small, peaceful fish that won't compete for food or resources. They are relatively hardy and easy to care for, making them a great choice for experienced and novice aquarists alike.
