Can You Put Neon Tetras With Pea Puffers? A Definitive Guide
Putting neon tetras with pea puffers is generally not recommended. Pea puffers are known to be fin-nippers and predatory, and neon tetras are an easy target.
This article will delve into the compatibility of neon tetras and pea puffers, exploring the reasons why they often make poor tankmates. We will discuss the temperament of both species, their environmental needs, and offer alternative tankmate options to ensure a peaceful and thriving aquarium.
Understanding Pea Puffer Behavior
Pea puffers, also known as dwarf puffers, are captivating fish due to their small size and curious nature. However, their charming appearance belies a predatory instinct that can be problematic in community tanks.
- Pea puffers are opportunistic hunters.
- They possess sharp beaks used to crush snails and other invertebrates.
- They are known to nip at the fins of slower-moving or long-finned fish.
- Individual temperaments can vary, but aggression towards tankmates is a common concern.
Neon Tetra Characteristics
Neon tetras are small, peaceful schooling fish that are a staple in the aquarium hobby. They are prized for their vibrant colors and generally docile nature.
- Neon tetras are social creatures and should be kept in groups of six or more.
- They are relatively small and defenseless.
- Their bright colors can attract the attention of predators.
- They prefer stable water parameters and a well-planted environment.
Why Neon Tetras and Pea Puffers Don’t Mix
The compatibility issues between neon tetras and pea puffers stem primarily from the pea puffer’s predatory nature and the neon tetra’s vulnerability. The simple answer to “Can you put neon tetras with pea puffers?” is generally no, and here’s why:
- Fin-nipping: Pea puffers are notorious fin-nippers, and neon tetras are a prime target due to their small size and relatively slow swimming speed. This can lead to stress, injury, and even death for the tetras.
- Predatory Instincts: Even if the pea puffers aren’t actively fin-nipping, their predatory instincts may cause them to constantly harass the neon tetras, creating a stressful environment.
- Size Disparity: The size difference between adult pea puffers and neon tetras is significant enough to make the tetras easy prey.
- Conflicting Needs: While both prefer planted tanks, the specific needs (like water flow and exact temperature parameters) can be slightly conflicting to the degree that both will not thrive as they would otherwise.
Alternative Tankmates for Neon Tetras
If you are considering setting up a community tank with neon tetras, here are some compatible tankmates:
- Other small, peaceful schooling fish like ember tetras or harlequin rasboras.
- Bottom-dwelling fish like Corydoras catfish.
- Small, peaceful invertebrates like Amano shrimp or Nerite snails. (Note: some puffers may still eat smaller snails).
Alternative Tankmates for Pea Puffers
Pea puffers are best kept in species-only tanks due to their aggressive nature. However, if you are determined to keep them with other fish, consider these carefully:
- Fast-moving fish that are larger than the pea puffers.
- Fish with very short fins that are not attractive targets for fin-nipping.
- Avoid fish with long, flowing fins or bright colors.
- Consider keeping only one pea puffer or a group in a very large, heavily planted tank to minimize aggression.
Creating a Suitable Habitat
Regardless of your tankmate choices, providing a suitable habitat is crucial for the health and well-being of your fish.
- Planted Tank: Both neon tetras and pea puffers thrive in well-planted tanks with plenty of hiding places.
- Stable Water Parameters: Maintain stable water parameters with regular water changes.
- Appropriate Filtration: Use a filter that provides adequate filtration without creating excessive water flow.
- Proper Lighting: Provide appropriate lighting for plant growth and to create a natural environment for your fish.
Monitoring Fish Behavior
Carefully monitor your fish’s behavior, especially when introducing new tankmates. Watch for signs of stress, such as:
- Hiding or inactivity.
- Fin-nipping or aggression.
- Loss of appetite.
- Changes in coloration.
If you observe any of these signs, separate the fish immediately to prevent further harm. The answer to “Can you put neon tetras with pea puffers?” is still no if you see this behavior; intervene.

Frequently Asked Questions
Can pea puffers live with any fish?
While pea puffers are often best kept in species-only tanks, it is possible to keep them with other fish if you choose tankmates carefully. Select fast-moving fish with short fins that are not easily stressed or targeted. Large tanks with heavy planting are a must.
What happens if pea puffers attack neon tetras?
If pea puffers attack neon tetras, the tetras will likely experience stress, fin damage, and potentially death. The continuous harassment and fin-nipping can lead to secondary infections and a weakened immune system.
Are there any specific neon tetra varieties that are more resistant to pea puffer attacks?
No, there are no neon tetra varieties that are inherently more resistant to pea puffer attacks. All neon tetras are equally vulnerable due to their small size and relatively slow swimming speed.
How can I distract pea puffers from attacking other fish?
You can try to distract pea puffers by providing a variety of enrichment activities, such as feeding live foods (snails, blackworms), rearranging the tank regularly, and offering plenty of hiding places. However, this may not completely eliminate their predatory behavior.
What is the minimum tank size for keeping pea puffers with other fish (if absolutely necessary)?
If you are determined to keep pea puffers with other fish, a minimum tank size of 20 gallons is recommended. This will provide more space for the fish to escape and reduce the likelihood of aggression. Remember that more space is always better.
Can I train pea puffers not to nip fins?
Unfortunately, you cannot train pea puffers not to nip fins. It is an instinctive behavior, and while some individuals may be less aggressive than others, it is impossible to completely eliminate this tendency.
What are the signs of stress in neon tetras?
Signs of stress in neon tetras include hiding, loss of appetite, clamped fins, pale coloration, and erratic swimming. If you observe these signs, investigate the cause and take corrective action immediately.
Are there any plants that are particularly helpful in creating a peaceful environment for neon tetras and pea puffers?
Dense plants like Java moss, Hornwort, and Anacharis are beneficial for creating a peaceful environment. They provide hiding places, break up sight lines, and help reduce stress for both neon tetras and pea puffers (though as we’ve established, keeping them together is not ideal).
How often should I feed pea puffers to minimize aggression?
Feeding pea puffers twice a day with a varied diet can help minimize aggression by ensuring they are not hungry. Offer a mix of live, frozen, and freeze-dried foods, such as snails, blackworms, and bloodworms.
What water parameters are ideal for keeping pea puffers and neon tetras (if kept together against recommendation)?
While the ideal solution is to keep them apart, if you insist, aim for a pH of around 7.0, a temperature of 76-78°F, and a hardness of 5-12 dGH. However, these parameters are not optimal for both species and are more of a compromise. Remember the primary advice when considering “Can you put neon tetras with pea puffers?” is still no.
What kind of filter is best for a tank with pea puffers?
A sponge filter or a hang-on-back (HOB) filter with adjustable flow is a good choice for a tank with pea puffers. Sponge filters are gentle and provide excellent biological filtration, while HOB filters offer more mechanical filtration. Avoid filters with strong currents.
If I already have neon tetras, is it possible to introduce pea puffers successfully?
Introducing pea puffers to a tank that already contains neon tetras is highly risky and not recommended. The pea puffers are likely to view the tetras as prey, and the established tetras may be stressed by the introduction of a new, predatory fish. The best course of action is to either rehome the pea puffers or the neon tetras.
