The Pea Puffer or the Pygmy Puffer Fish is the tiniest pufferfish in the freshwater habitat in the world, which measures up to 2.5 cm (1 inch). These small fish are indigenous to the fertile creeks and lakes in Kerala, India, and are popular amongst aquarists who enjoy exotic and interactive species. They are curious in nature, with an odd eye movement and dark spots in the eyes that make them appear as bright greenish-yellow bodies, making them an excellent focal point in any nano aquarium.
