Dwarf Freshwater Pea Puffer
Pea Puffers, also known as Dwarf Puffer Fish, are one of the most unique and sought-after nano fish in the aquarium hobby. Known for their bold personalities, hunting behavior, and interactive nature, these tiny freshwater puffers deliver far more character than their size suggests.
Unlike most other nano fish for sale, pea puffers are carnivorous and highly territorial, making them best suited for species-only aquariums or carefully managed setups. They are especially popular for their ability to hunt and eat snails, making them both entertaining and functional in the right tank.
At The Shrimp Farm, you can buy healthy, active pea puffers online with fast, safe shipping and a live arrival guarantee. Whether you're building a dedicated puffer tank or looking for a truly unique nano fish, pea puffers are an unforgettable addition to any freshwater aquarium.

What do Freshwater Pea Puffers eat?
Pea puffers are true carnivores and thrive on live foods. In the wild and aquarium, they actively hunt:
- Bladder Snails (their favorite)
- Daphnia and micro crustaceans
- Bloodworms and blackworms
- Small insect larvae
They rarely accept dry foods, so a live or frozen diet is essential for long-term health.
Pro tip: Keeping a small snail colony ensures a constant, natural food source.
Are Pea Puffers Aggressive?
Despite their tiny size, the Pea Puffer is known for having a bold and territorial personality. Unlike most nano fish, pea puffers are not peaceful community fish and can display surprising levels of aggression—especially in confined spaces.
What Makes Pea Puffers Aggressive?
Pea puffers are naturally territorial hunters. In the wild, they defend small areas packed with food sources like snails and micro-crustaceans. That instinct carries over into the aquarium, where they may:
- Nip at slower-moving fish
- Harass tank mates
- Compete aggressively for food
- Establish and defend small territories
Can Pea Puffers Live with Other Fish?
In most cases, pea puffers are best kept in a species-only tank. While some experienced aquarists have limited success with carefully chosen tank mates, it’s not recommended if your goal is a stress-free community aquarium.
Can Pea Puffers Live Together?
Yes—but with conditions:
- Keep them in groups of 3–6 or more
- Provide heavy planting and visual barriers
- Avoid overcrowding (minimum ~5 gallons, more for groups)
When properly set up, aggression is usually reduced to minor chasing rather than constant fighting.
How to Reduce Aggression
You can manage pea puffer aggression with the right setup:
- Add dense plants and hiding spots
- Maintain proper tank size
- Feed regularly with high-protein foods (like snails and frozen options)
- Avoid mixing with long-finned or slow fish
Bottom Line
Pea puffers are highly interactive and entertaining, but they’re not your typical peaceful nano fish. If you’re looking for personality and don’t mind a species-only setup, their feisty nature is part of what makes them so unique.

Dwarf Freshwater Pea Puffer
Carinotetraodon Travancoricus, also known as the dwarf pea puffer, is a dwarf fish species known for having a striking pattern and coloration that will draw instant attention. These small fish are appreciated by hobbyists for their unique look and personality. They are the perfect addition to a planted tank or a tank with other small fish, however, we do not recommend keeping them with shrimp.
Dwarf Pea Puffer Behavior
Dwarf pea puffers are very territorial and become aggressive, especially with limited hiding spots. However, they are typically safe to keep with most small fish and other dwarf pea puffers in smaller numbers.
Dwarf pea puffers exhibit a fascinating personality and are an excellent addition to planted tanks or small community tanks, plus as an added bonus they will eat small pest snails!
Dwarf Pea Puffer Care
A carnivorous diet is ideal for the dwarf pea puffer. They often will not eat dry foods, but frozen foods such as bloodworms will be eaten successfully. As stated above, the dwarf pea puffers will also happily snack on small pest bladder snails, or any other small snails in the tank. Find out more about Dwarf Pea Puffer in The Shrimp Farm University.
Buying Dwarf Pea Puffers
Dwarf Pea Puffers are an excellent addition to any planted tank since they do not eat live plants or disturb your substrate. They will liven up your tank with their facinating personality and add some unique coloration with their striking patterns.
Pea Puffer Care Guide (Complete Setup, Feeding & Tank Tips)
The Pea Puffer is one of the most unique nano fish in the hobby—tiny, intelligent, and full of personality. But unlike typical community fish, pea puffers have specific care requirements. Follow this complete guide to keep your fish healthy, active, and thriving.
Tank Size & Setup
Pea puffers do best in heavily planted aquariums that mimic their natural habitat.
- Minimum tank size: 5 gallons (10+ gallons recommended for groups)
- Aquascape: Dense plants, driftwood, and hiding spots
- Substrate: Sand or fine gravel
- Filtration: Gentle flow (they dislike strong currents)
- Lighting: Moderate (to support plant growth)
A well-planted tank helps reduce aggression and stress, especially when keeping multiple pea puffers.
Water Parameters
Stable water conditions are critical for long-term health.
- Temperature: 74–82°F
- pH: 6.5–7.5
- Hardness: Soft to moderately hard water
- Ammonia/Nitrite: 0 ppm
- Nitrate: <20 ppm
Regular water changes (20–30% weekly) will keep your pea puffers in peak condition.
Diet & Feeding for Dwarf Freshwater Pea Puffers
Pea puffers are strict carnivores and require a protein-rich diet.
- Primary foods:
- Snails (ramshorn, bladder snails)
- Frozen bloodworms
- Live blackworms or daphnia
- Feeding frequency: 1–2 times daily
- Important: They often refuse dry foods or flakes
Snails are especially important—they help wear down the puffer’s beak and support natural hunting behavior.
Temperament & Tank Mates for Pea Puffers
Pea puffers are territorial and semi-aggressive, despite their small size.
- Best kept in a species-only tank
- May nip fins or harass other fish
- Can be kept in groups with proper setup:
- 3–6+ fish
- heavily planted
- Adequate space
Avoid slow-moving or long-finned tank mates.
How Many Pea Puffers Per Gallon?
A common question with a simple rule:
- 1 pea puffer per 3–5 gallons
- Always provide extra space and hiding spots
Overcrowding increases aggression and stress.
Lifespan & Growth
- Average lifespan: 3–5 years
- Adult size: ~1 inch
With proper care, pea puffers remain active and interactive for years.
Pro Tips for Success
- ✔ Keep a steady supply of snails for feeding
- ✔ Use plants to break line-of-sight and reduce aggression
- ✔ Maintain stable water—pea puffers don’t tolerate swings
- ✔ Observe feeding to ensure each fish gets adequate food
Pea Puffer vs Other Nano Fish
| Feature | Pea Puffer | Typical Nano Fish |
|---|---|---|
| Temperament | Aggressive | Peaceful |
| Diet | Carnivore (snails) | Omnivore |
| Community Safe | ❌ No | ✅ Yes |
| Personality | Very interactive | Mild |
How big do Dwarf Pea Puffers get?
At a maximum size of around 1 inch, Dwarf Pea Puffers stay quite small.
How many Dwarf Pea Puffers can I keep per gallon?
Groups of 3 Dwarf Pea Puffers or less is ideal for a 10-gallon, but they can be kept by themselves with no problem. We recommend these small numbers because this fish can be very territorial and sometimes aggressive to other fish, including other Dwarf Pea Pufffers.
How long do Dwarf Pea Puffers live?
2-4 years is the average lifespan of a Dwarf Pea Puffer.
Are Dwarf Pea Puffers easy to Breed?
Breeding Dwarf Pea Puffers is moderately easy. Often times, if a male and female Dwarf Pea Puffer are in the same tank, the male will chase the female around for a while until they go into hiding to fertilize the eggs. Once the eggs have been fertilized, you will need to remove the adult Dwarf Pea Puffers to another tank to prevent them from eating the fry.
What is the diet of Dwarf Pea Puffers?
Dwarf Pea Puffers will thrive and remain very colorful on a varied diet of mostly carnivorous foods. Dwarf Pea Puffers will often not eat dry foods, but frozen foods such as bloodworms will be accepted. One benefit of having Dwarf Pea Puffers is that one of their favorite snacks is eating small snails, including small pest snails that are often found in planted tanks.
What are the best tankmates for Dwarf Pea Puffers?
Dwarf Pea Puffers, in general, are pretty territorial and do not always get along with other fish. We definitely DO NOT recommend putting them in the same tank as shrimp. We recommend keeping Dwarf Pea Puffers in smaller numbers of 3 or less because they are known to thrive when in small groups due to their territorial nature.
Feel free to add small snails to the tank for them to snack on. Most other fish (other than Betas) are safe to keep with Dwarf Pea Puffers, but watch closely for aggression at first. They also LOVE planted tanks due to extra nutrients and hiding places.
What is the best way to Acclimate my new Dwarf Pea Puffer?
When adding new tankmates to your already existing tank, it is important to take the proper steps in introducing and acclimating them into their new home. The whole process is extremely stressful for the fish. Acclimation is important for fish as it allows them time to adjust to the temperature and parameters of their new environment. By doing this correctly, you will reduce the chances of shock or death of your new crayfish. We recommend drip acclimation for fish as it is generally the best option to adjust them slowly to your tank. You can find our Premium Drip Acclimation Kit here.
