Pea Puffer Fish: A Small Fish with a Big Personality
Pea puffer fish, also known as dwarf puffer fish (Carinotetraodon travancoricus), are one of the most fascinating freshwater fish in the aquarium hobby. Native to slow-moving rivers and lakes in India, these tiny puffers may only reach about one inch in size, but they’re packed with personality, intelligence, and charm. At Natural Environment Aquatix, pea puffers are a favorite among aquarists looking for something truly unique.
Why Pea Puffer Fish Are So Popular
Pea puffers are known for their expressive eyes, curious behavior, and interactive nature. Unlike many small community fish, pea puffers actively recognize their environment and even appear to watch their owners. Their compact size makes them ideal for smaller aquariums, but don’t let their size fool you—these fish have bold attitudes and require thoughtful care.
They’re also one of the few true freshwater puffer fish, meaning no brackish or saltwater conditions are needed, making them accessible for freshwater hobbyists ready for a challenge.
Tank Requirements for Pea Puffers
A well-planted aquarium is essential for pea puffers. Dense vegetation using live plants like Java Fern, Anubias, Cryptocoryne, and floating plants helps reduce stress and break up sightlines.
Recommended tank setup:
-
Minimum tank size: 10 gallons (larger is better for groups)
-
Temperature: 74–82°F
-
pH: 6.5–7.5
-
Filtration: Gentle flow with strong biological filtration
-
Substrate: Sand or fine gravel
Pea puffers do best in species-only tanks or carefully planned setups. They are territorial and may nip fins, making them unsuitable for most community aquariums.
What Do Pea Puffer Fish Eat?
Pea puffers are carnivores and thrive on a diet of frozen and live foods. They often refuse dry foods, so proper feeding is crucial.
Preferred foods include:
-
Frozen bloodworms
-
Live or frozen brine shrimp
-
Blackworms
-
Small snails (great for dental health)
Feeding a varied diet keeps them healthy and engaged, while also helping prevent overgrown teeth—a common issue in puffer fish.
Can Pea Puffers Be Kept Together?
Yes, but with care. Pea puffers can be kept in small groups when provided with enough space and visual barriers. A heavily planted tank helps reduce aggression, and maintaining more females than males is recommended. Observing behavior closely is key to long-term success.
