Let's talk about this really cool freshwater fish species by checking out the Species Profile for the Pea puffer.

They're cute, petite, unique-looking, and have interesting personalities, making them a favorite of mine and many freshwater aquarium enthusiasts.


Pea Puffers, also known as Dwarf Puffers or Malabar Puffers, are native to freshwater rivers and streams in southwestern India. Specifically, they can be found near Kerala and Karnataka, India. They love slow-moving and densely vegetated waters, where they can find shelter among plants and food.


Pea Puffers are small, up to a maximum length of 1-1.5 inches (2.5-3.8 cm). They have a rounded body shape with a spotted pattern in shades of green and brown. Their eyes are large and mobile, giving them a curious appearance as they explore their surroundings. Males tend to have more vivid coloration and a dark stripe along the belly, while females are more round-bodied.


Pea Puffers are known for being curious and inquisitive. They're active swimmers and like to explore their environment. However, they can be territorial and aggressive towards their tankmates, especially if they feel crowded. So, giving them a spacious and well-decorated aquarium is essential to minimize aggression and stress.


As for their diet, Pea Puffers primarily feed on small crustaceans and mollusks in the wild. In an aquarium, they should be offered a varied diet of live and frozen foods, such as brine shrimp, daphnia, bloodworms, and snails. Feeding snails from my other tanks is one of my favorite things to do. It's best to provide them with small portions 2-3 times daily.


A 10-gallon (38-liter) tank is the minimum size recommended for a single puffer, with an additional 5 gallons (19 liters) for each additional puffer. To mimic their natural habitat, the tank should be well-planted with various live species, like Java moss, Java fern, and Anubias. Driftwood, rocks, and caves should also be included to provide hiding spots and territorial boundaries.

Pea Puffers love planted tanks.

Pea Puffers thrive in water with a pH range of 6.5-7.5 and a temperature range of 74-82°F(23-28°C). A heater should maintain a consistent temperature, and a gentle filtration system should be in place to keep the water clean without creating strong currents. Regular water changes, around 25-30% weekly, are essential to maintain good water quality and prevent the buildup of toxins.




It can be challenging if you're interested in breeding Pea Puffers, but it's possible with the right conditions. A separate breeding tank should be set up with dense vegetation and hiding spots to encourage breeding. Introduce a healthy, well-fed pair of puffers and monitor their behavior closely. Males will court females by displaying their colors and swimming patterns.


Once spawning occurs, the female will lay her eggs on a flat surface, like a plant leaf or smooth rock. The male will fertilize the eggs, and the pair should be removed from the breeding tank to prevent them from consuming the eggs or fry. The eggs will hatch within 5-7 days. Initially, the fry should be fed infusoria or other microscopic food sources and then transitioned to baby brine shrimp and other small foods as they grow.


Pea Puffers are generally hardy fish but susceptible to common fish diseases like ich, fin rot, and bacterial infections. Maintaining a clean and stable environment is the best way to keep your puffers healthy. If you notice any signs of illness, like lethargy, loss of appetite, or changes in appearance, give us a call and we can recommend the best course of action.





Pea Puffers are a fascinating and unique addition to the aquarium hobby. They offer endless hours of enjoyment for their owners with their inquisitive nature, small size, and intriguing appearance. These captivating fish can thrive in a home aquarium with proper care, a well-maintained aquarium, and a suitable diet. Whether you're a novice or an experienced aquarist, Pea Puffers are worth considering for your aquarium!
