How Long Do Pea Puffers Live?

Your little fish friend will be around to share in your Netflix binges for anywhere from 4 to 5 years, depending on care and water quality. Just don’t ask them for opinions on what to watch next; they tend to be indecisive.

Creating a good habitat, clean water, and a healthy diet can improve their lifespan.

How Big do Pea Puffers Grow?

Pea Puffers are one of the smallest pufferfish, this small fish maxes out at around 1 to 1.5 inches in length. Despite their small size, they are full of personality and can be quite active and curious.

Sexing Pea Puffers

Generally, males tend to be more colorful and have a darker line or “wrinkle” running down their belly, while females might be slightly rounder and less colorful. Observing their behavior can also give clues to their sex, as males might show more territorial tendencies.


Optimal Water Conditions for Pea Puffers

Pea Puffers hail from the freshwater rivers and lakes of South and Southeast Asia, such as India, where the water conditions are unique. To replicate their natural habitat and ensure a healthy environment, attention should be paid to their water parameters.

Temperature: Pea Puffers thrive in water temperatures between 74-82℉. Maintaining this temperature range ensures a comfortable environment that mirrors their native waters. Drastic changes or cooler temperatures may lead to stress and health issues.

pH Level: Pea Puffers prefer slightly acidic to neutral water, with a pH range of 7.0-7.5.

Water Hardness: Soft to moderately hard water is ideal for Pea Puffers, with a general hardness (GH) of 5-15° and a carbonate hardness (KH) of 4-12°.

Water Quality: Regular monitoring of ammonia, nitrite, and nitrate levels is crucial. Pea Puffers can be sensitive to poor water quality, so aim for 0 parts per million for ammonia and nitrite and keep nitrate levels as low as possible (preferably under 20 ppm).

Remember: Consistent water parameters are key.

Remember: they can be aggressive, so watch their behavior and provide ample space for them to establish territories.

Compatible Tank Mates for Pea Puffers

Considering other species for your tank? Be careful; pea puffers aren’t huge fans of sharing their toys. Many aquarists view pea puffers as species only tank inhabitants. 

Pea Puffers, while small and charismatic, can be a bit feisty and territorial. Finding suitable tank mates for them requires some careful consideration to ensure a harmonious aquatic environment.

Aggressive or large species should be avoided, as they might either bully or become targets for the Pea Puffers. Also, if kept with other Pea Puffers, sufficient space and hiding spots are necessary to prevent conflicts.

✅ Good Potential Pea Puffer Tank Mates Include:

  • Otocinclus Catfish
  • Shrimp (like Cherry Shrimp or Ghost Shrimp)
  • Snails (like Nerite Snails or Mystery Snails)
  • Small, Non-Aggressive Rasboras
  • Non-Nippy Tetras (such as Ember Tetras)

⛔ Steer Clear of These Tank Mates:

  • Large Cichlids
  • Barbs (which can be nippy)
  • Aggressive Betta Fish
  • Any Fish That Might View Pea Puffers as Food

Remember: every Pea Puffer has its personality, and careful observation is required to ensure that all inhabitants of the tank are getting along. If you notice signs of stress or aggression, it might be wise to rethink the tank’s composition.


Pea Puffer Diet

Like that friend who’s always on a new diet trend, pea puffers can be picky eaters. Their carnivorous diet (Frozen Foods & Brine Shrimp) includes freeze-dried foods, frozen bloodworms, and small snails. Yes, they eat small snails.

How Often Should I Feed My Pea Puffer?

Feed them once or twice a day, but remove any uneaten food. They’re neat eaters, not messy ones.

Note: Tank bred dwarf pea puffers might accept dry foods, but wild caught specimens usually stick to live and frozen foods.

Breeding Pea Puffers

Here are 5 Quick Tips for Breeding Pea Puffers:

  1. Select Healthy, Compatible Pairs
  2. Create a Suitable Environment
  3. Offer a Varied Diet
  4. Monitor Water Conditions
  5. Exercise Patience and Diligence

Note: Breeding Pea Puffers is a complex task and is typically only attempted by experienced aquarists. Their territorial nature and specific requirements make breeding a delicate process.

How Do I Condition Pea Puffers to Spawn?

Conditioning Pea Puffers to spawn involves a combination of proper feeding and the right environment. Offering live foods like snails and maintaining clean water with soft and slightly acidic pH will encourage breeding behavior.

Soft music and candlelight are optional.

How Can I Tell if a Pea Puffer is Pregnant?

Pea Puffers don’t have easily discernible physical changes to indicate readiness to breed. However, a female pea puffer gets plumper (Don’t comment on her weight though; it’s rude.) Males might show increased interest in the female and might be seen following her around the tank.

When ready to spawn, the female will lay her eggs on the underside of a leaf or other surface. The male will then fertilize the eggs.

Raising the Fry

If breeding is successful, be prepared to care for the fry. They will require microscopic live food like infusoria at first, gradually moving to larger food like baby brine shrimp as they grow.

Remember: Like conducting a finely tuned orchestra, breeding Pea Puffers demands patience, careful observation, and attention to detail. If you feel the call to this challenge, arm yourself with knowledge and dedication, and you may find yourself rewarded with the delightful dance of tiny Pea Puffer fry.
