Overview of Pea Puffers
Common Names: Pea Pufferfish, Dwarf Puffer Fish, Malabar Pufferfish, Pygmy Pufferfish
Scientific Name: Carinotetraodon travancoricus
Origin: South-West India
Size: 1–1.5 inches (2.5–3.8 cm)
Lifespan: 4–5 years with proper care
Temperament: Territorial, active, and inquisitive
Pea Puffers are freshwater fish, unlike most other puffer species that are typically found in brackish or saltwater environments. They’re known for their intelligence, interactive behavior, and beautiful coloration, but they require specific care to stay healthy and happy.
Ideal Tank Requirements for Pea Puffers
Pea Puffers are unique in that they don’t require a large tank, making them suitable for smaller setups. However, they are highly territorial and active fish that benefit from a well-structured environment with plenty of hiding spots and decorations.
When setting up your puffer tank, it’s important to create a lot of hiding places, plants en things to explore. Dwarf Puffer fish are quite intelligent and get bored very easily. Make sure your decoration breaks the the tank up in different ereas, Dwarf Puffers are territorial fish and known to defend their territories heavily.
Filtration for Pea Puffer Tanks
Filtration is crucial for maintaining good water quality and a healthy tank environment. Due to their messy eating habits, Pea Puffers contribute significantly to the tank’s bioload, so having a robust filtration system is essential.
- Filter Size: Aim for a filter that’s rated for double the volume of your tank. For example, if you have a 20-gallon tank, use a filter rated for 40 gallons.
- Filter Media: Fill your filter with plenty of biological media (such as ceramic rings or bio-balls) to support beneficial bacteria, which helps break down waste. Mechanical media, like sponge or filter floss, can help remove debris from the water.
- Water Changes: Regular water changes are necessary to maintain water quality. Changing 20% of the water each week is recommended, though some aquarists find success with 40% bi-weekly changes.

Tank Mates for Pea Puffers: Proceed with Caution
Dwarf Pea Puffers are known for their feisty and territorial nature, making them challenging to keep in community tanks. They tend to nip at the fins of other fish and may harass smaller or slower-moving tank mates.
If you’re interested in adding tank mates, here are a few tips:
- Cherry Shrimp: Some aquarists have had success keeping Pea Puffers with Cherry Shrimp, as they are often too large for Pea Puffers to eat. However, this is still risky, as Pea Puffers may hunt or harass shrimp if they’re feeling territorial.
- Snails: Snails can sometimes be kept with Pea Puffers, though they’re often seen as a snack. Ramshorn and Malaysian Trumpet Snails may last longer due to their hard shells, but expect occasional losses.
Important: Always introduce new tank mates carefully and observe behavior. If aggression becomes an issue, be prepared to separate the fish.
Diet and Feeding for Pea Puffers
Pea Puffers are strict carnivores with a strong hunting instinct. In the wild, they feed on small invertebrates and are known to enjoy a diet of live or frozen foods in captivity.
Recommended Foods:
- Frozen or Live Bloodworms
- Live Snails: Pea Puffers love to hunt snails, which also helps control their natural teeth growth.
- Frozen Brine Shrimp
- Frozen or Live Blackworms
Tip: Mixing up their diet is important to ensure they receive the nutrients they need. Feeding a varied diet of different protein sources prevents nutritional deficiencies and keeps your Pea Puffers excited about mealtime. Aim to feed them once a day, but avoid overfeeding, as they can be prone to obesity.

Health and Disease Prevention
Pea Puffers are generally hardy, but they’re still susceptible to common freshwater fish diseases like Ich or fungal infections. Maintaining clean water and a stable environment is the best way to prevent illness.
- Ich: Pea Puffers are susceptible to Ich, a parasitic disease that appears as white spots on the body and fins. Ich can be treated with temperature adjustments and Ich-specific medications.
- Fungal Infections: Pea Puffers are prone to fungal infections if water quality is poor or if they are stressed. Proper filtration and regular water changes can reduce the likelihood of fungal issues.
General Tips:
Quarantine New Additions: If you plan to add new fish, always quarantine them for a couple of weeks to prevent diseases from entering your main tank.Stable Environment: Keep tank parameters consistent. Fluctuating temperatures and pH levels can weaken Pea Puffers’ immune systems.

Pea Puffers are unique in that they don’t require a large tank, making them suitable for smaller setups. However, they are highly territorial and active fish that benefit from a well-structured environment with plenty of hiding spots and decorations.
- Tank Size: A single Pea Puffer needs at least a 5-gallon (19L) tank. For each additional Pea Puffer, add 3 gallons (11L). Remember, more space is always better to reduce aggression.
- Temperature: 74–82°F (23–27°C). Consistent temperature is key, so consider using a heater to maintain stability.
- pH: Pea Puffers are adaptable to pH levels between 6.8 and 8.3. Stability is more critical than hitting an exact pH.
- Water Hardness (GH): 5–25 dGH.
Aquascaping for Pea Puffers: To prevent boredom and aggression, create a tank environment filled with live plants, caves, and decorations that create different territories and hiding spots. They enjoy exploring and will defend their space, so adding structures that break up the tank’s line of sight can help reduce territorial disputes.
