Pea Pufferfish: A Complete Guide to Caring for These Tiny, Fascinating Fish

If you’re looking for a unique and interesting addition to your aquarium, the pea pufferfish (also known as the dwarf pufferfish) might be the perfect choice!

These tiny fish are full of personality, and despite their small size, they can be quite feisty and fun to watch.

In this post, we’ll cover everything you need to know about caring for pea pufferfish, including their habitat, feeding habits, behavior, and tips for keeping them happy and healthy in your aquarium.

What Is a Pea Pufferfish?

The pea pufferfish (Carinotetraodon travancoricus) is a small species of freshwater pufferfish native to the rivers and lakes of India.

Known for their small size—they grow to be only about 1 inch long—they are often called dwarf pufferfish.

Despite their tiny stature, pea puffers have a bold and curious nature, making them an exciting choice for aquarium enthusiasts.

Fun fact: Unlike many other pufferfish, pea puffers live in freshwater, which makes them easier to keep for beginners compared to their saltwater cousins.

Why Pea Puffers Make Great Pets

There are several reasons why pea puffers are becoming a popular choice for aquarium hobbyists:

• Size: Their small size makes them perfect for smaller tanks or nano aquariums.
• Personality: Pea puffers are known for their lively and curious nature. They are intelligent, interactive, and even learn to recognize their owners!
• Unique Appearance: With their big, round eyes, rotund bodies, and distinct patterns, pea puffers are visually captivating.
• Active Swimmers: Unlike some fish that tend to hide, pea puffers are active swimmers and love exploring their surroundings.

Setting Up the Ideal Habitat for Your Pea Pufferfish

Creating the right environment is essential to keeping your pea puffers healthy and happy. Here’s what you need to know:

1. Tank Size

Although pea puffers are small, they need ample space to swim and explore. A minimum tank size of 10 gallons is recommended for a single pea puffer, but if you plan on keeping more than one, you’ll need a larger tank.

For a group of three to four puffers, a 20-gallon tank is ideal to reduce territorial aggression.

2. Water Conditions

Pea puffers thrive in clean, well-maintained water. Here are the ideal water parameters for them:

• Temperature: 74°F to 82°F (23°C to 28°C)
• pH: 6.5 to 7.5
• Hardness: 5-15 dGH

Make sure to use a reliable heater and filtration system to maintain these conditions. Regular water changes (about 25% weekly) are essential to keeping ammonia and nitrate levels low, which can be harmful to your pufferfish.

3. Tank Setup and Decoration

Pea puffers are curious and love exploring their environment, so it’s important to create a tank that mimics their natural habitat:

• Plants: Dense planting with live plants such as Java moss, Anubias, or Java ferns gives them places to hide and feel secure. Pea puffers also enjoy swimming through plant leaves.
• Hiding Spots: Adding caves, driftwood, and rocks will provide your puffers with places to retreat to and reduce stress.
• Substrate: A soft sand or fine gravel substrate is recommended, as pea puffers often rest at the bottom of the tank.

Pro tip: Pea puffers can be aggressive toward each other, so having plenty of hiding spaces helps minimize territorial disputes.

Feeding Your Pea Pufferfish

Pea puffers are carnivorous and have specific dietary needs. They don’t usually accept dry fish food, so it’s important to offer a variety of live or frozen foods.

Here are some of their favorite foods:

• Bloodworms (live or frozen)
• Brine shrimp (live or frozen)
• Daphnia
• Snails (they especially love eating small pest snails like ramshorn or bladder snails)

Why snails?
Pea puffers have tiny but sharp beaks that continue to grow throughout their lives. Snails provide the necessary crunch to keep their teeth worn down, preventing overgrowth, which can lead to feeding issues.

Feeding tip: Feed your pea puffers once or twice a day, but avoid overfeeding. Their small size means they don’t need a lot of food, and uneaten food can quickly foul the water.

Pea Puffer Behavior: What to Expect

Pea puffers are known for their unique and often bold behavior. Unlike some other small fish, they are active swimmers and like to interact with their environment.

1. Territorial Nature

Pea puffers can be territorial, especially males. They may chase and nip at other fish, which is why they are best kept in a species-only tank or with very specific tank mates (more on that later). If you have multiple puffers, providing plenty of hiding spots and plants helps reduce aggression.

2. Social Behavior

Pea puffers are not schooling fish, but they can be kept in small groups if the tank is large enough and there are plenty of places to hide. In a group, you may notice some interesting social dynamics, like mild displays of dominance, especially between males.

3. Recognizing Their Owners

One of the most charming aspects of pea puffers is that they can recognize their owners! Over time, they may swim to the front of the tank when they see you, especially during feeding times. Their interactive and curious nature makes them a joy to watch.

Tank Mates: Can Pea Puffers Live with Other Fish?

Pea puffers are best kept in a species-only tank, as they can be aggressive and nip at other fish. However, if you want to add tank mates, there are a few species that may coexist peacefully with pea puffers. These include:

• Fast-moving fish: Species like neon tetras or zebra danios may work, as they’re quick enough to avoid the puffers.
• Bottom dwellers: Fish like corydoras or otos are less likely to be harassed, as they tend to stay at the bottom of the tank while puffers swim in the middle.

Always monitor interactions closely when introducing new tank mates, and be ready to separate them if aggression occurs.

Tips for Keeping Pea Puffers Happy and Healthy

1. Maintain Clean Water
Pea puffers are sensitive to water quality, so regular water changes and tank maintenance are key to preventing illness.

2. Watch for Aggression
If you notice one puffer being particularly aggressive toward another, consider separating them to avoid injury.

3. Enrich Their Environment
Pea puffers are intelligent and curious, so adding new plants, decorations, or rearranging their habitat from time to time can keep them stimulated.

4. Provide a Varied Diet
Offer a variety of foods to keep your pea puffers healthy and ensure they get all the nutrients they need.

Why Pea Puffers Are Amazing Pets

Pea puffers may be small, but they pack a lot of personality into their tiny bodies. Caring for pea puffers is a rewarding experience, as they are interactive, fun to watch, and bring a lot of life to a well-planned aquarium.

With the right setup, diet, and care, these fascinating fish can thrive in your home aquarium, providing endless entertainment.

Whether you’re a beginner or an experienced aquarium enthusiast, pea puffers are a delightful addition to any tank. Consider adding a pea puffer to your aquarium and enjoy the unique charm they bring!
