Pea Puffer Fish

Pea Puffer Fish (Carinotetraodon travancoricus)

The Pea Puffer Fish, also known as the Dwarf Puffer, is one of the smallest and most personality-packed freshwater fish in the aquarium hobby. Despite reaching only about an inch in length, these tiny puffers are full of character, intelligence, and curiosity. Their bright green-gold bodies, expressive eyes, and constant interaction with their environment make them a favorite among nano aquarium enthusiasts.

Native to the freshwater rivers and lakes of India, Pea Puffers are true freshwater fish that spend their days actively exploring plants, driftwood, and hardscape in search of food. Unlike many small community fish, they display remarkable intelligence and often learn to recognize their owners, eagerly swimming to the front of the aquarium at feeding time.

Pea Puffers thrive in heavily planted aquariums with plenty of hiding places and visual barriers. Their curious nature keeps them constantly on the move, investigating every corner of the tank. They require a protein-rich diet and particularly enjoy snails, frozen bloodworms, brine shrimp, and other meaty foods. Their natural hunting instincts and engaging behavior make them one of the most entertaining freshwater fish available.
