If you’re wondering whether your pet axolotl needs a tank mate, you’ve come to the right place. In the wild, axolotls are social animals that live in groups. But when kept as pets, they can thrive on their own or in pairs.

Read on as we dive into the pros and cons of keeping axolotls alone versus in groups.

Axolotls are unique aquatic salamanders that have captured the hearts of aquarium hobbyists. With their feathery gills, wide mouths, and perpetual baby-faced looks, it’s easy to see why they make endearing pets.

As you prepare to welcome an axolotl or two into your home, an important consideration is whether these salamanders need companionship or do well on their own.

The Social Nature of Axolotls

They Live in Large Groups in the Wild

Axolotls are highly social creatures that tend to live in large groups in their natural habitat. In the wild, they are found exclusively in Lake Xochimilco and Lake Chalco in Mexico City. These lakes used to contain up to 6,000 axolotls per square kilometer before urbanization caused their populations to decline dramatically.

Today, axolotls are critically endangered in the wild due to habitat loss and predation by invasive species like tilapia and carp.

Axolotls live in groups because there is safety in numbers – being part of a large group helps protect axolotls from predation. They also benefit from living communally by having more opportunities to find mates and reproduce. Living in groups enables information sharing and learning among axolotls.

Axolotls Recognize and Interact with Each Other

Far from being solitary creatures, axolotls have surprisingly complex social behaviors and interactions. Researchers have found that axolotls are able to identify and differentiate between other individual axolotls.

They can recognize tank mates through chemical cues and will establish social hierarchies within groups.

Axolotls demonstrate social behaviors like following and nipping one another. They communicate by releasing pheromones and posture changes. Their external gills also flush red during social interactions. Same-sex axolotls may fight, especially during breeding season, to establish dominance.

Some Benefits of Keeping Axolotls in Groups

Given their highly social nature, most experts recommend keeping pet axolotls in groups. Some key benefits of keeping communal tanks include:

  • Reduced stress and aggression – Axolotls feel more secure and relaxed in groups.
  • Natural social behaviors – Axolotls can interact with tank mates.
  • Mental stimulation – Group housing enriches the axolotls’ environment.
  • Backup food source – Axolotls may nibble on a dead tank mate.

That said, group housing does come with some risks like nipping tank mates’ gills or spreading disease. Experts recommend keeping no more than 4-5 axolotls per 10-gallon tank. The axolotls should be similar in size and introduced together young.

Potential Downsides of Housing Axolotls Together

Risk of Bullying and Nipping

Although axolotls are typically peaceful creatures, housing them together does come with some risks. One potential downside is the possibility of bullying and nipping among tank mates.

Axolotls have small teeth that they sometimes use to establish dominance and defend territory. One axolotl may chase, bite, or nip at another. This can lead to injuries or stress.

Younger, smaller, or weaker axolotls are especially vulnerable to being bullied. Without proper precautions, they could become malnourished or even attacked by tankmates competing for food.

Greater Competition for Food

Speaking of food, housing axolotls together means more competition at feeding time. Axolotls are voracious eaters and some may try to hog all the food.

If one axolotl gobbles up meals faster than the rest, tankmates can be left hungry. Underfed axolotls may not thrive and can become stressed.

To help curb food aggression, it’s best to scatter food widely throughout the tank rather than dumping it all in one place. This allows all axolotls access to nutrients.

Increased Bioload and Waste

More axolotls in a tank means more waste being produced. Their high metabolism and carnivorous diet creates significant bioactive waste.

As per Axolotl Central, a single adult axolotl can produce the same waste as a medium-sized dog. Now imagine multiple axies in one tank!

Without proper tank maintenance, ammonia and nitrates can accumulate to toxic levels. This chemical imbalance can stress, sicken, or even kill tank inhabitants.

1 Axolotl 25% Weekly
2-3 Axolotls 50% Weekly

Tips for Successfully Keeping Multiple Axolotls

Choose Tankmates of Similar Size

When housing multiple axolotls together, it’s important to choose tankmates that are similar in size and age. Axolotls have a complex social hierarchy and larger, older individuals may bully or prey on smaller tankmates.

To minimize aggression and cannibalism, select axolotls that are within an inch or two of the same length.

Provide Ample Space and Hideaways

Axolotls need room to establish their own territories. For 2-3 axolotls, aim for a tank size of at least 40 gallons. Provide plenty of hides, plants, rocks, and other decor to break up lines of sight and allow each axolotl to claim its own personal space.

Adding visual barriers helps diffuse territorial behavior.

Monitor for Signs of Stress and Aggression

Even in ideal conditions, axolotls may squabble over territory or food. Watch for nipped gills, legs, or tails as this can indicate bullying. Aggressive animals may need to be separated. Stressed axolotls may stop eating or lose their feathery external gills.

If any individuals seem under duress, move them to their own tank.

Feed in Separate Containers

To prevent food aggression, it’s best to feed housed axolotls in separate plastic containers. Move each axolotl to its own feeding tub and give them 10-15 minutes to eat their meal undisturbed. This ensures every axolotl gets its fair share and allows you to monitor each animal’s appetite and health.

By selecting appropriate tankmates, providing sufficient space, and feeding separately, you can successfully keep multiple axolotls. However, it’s still important to watch for signs of stress and be prepared to separate any individuals that don’t get along harmoniously.

Caring for a Solitary Axolotl

They Can Thrive on Their Own

Contrary to popular belief, axolotls do not require companionship from other axolotls to live a happy and healthy life. In fact, axolotls are perfectly content being housed alone. This is due to their reclusive nature and low social needs.

Axolotls tend to ignore each other when housed together and can even become aggressive towards one another, especially when competing for food or space. So you can rest easy knowing your solo axie will thrive on their own.

Give Them Plenty of Enrichment

Just because axolotls are solitary creatures does not mean they don’t need mental stimulation. Here are some great ways to enrich the life of your lone axolotl:

  • Provide plenty of hiding spots and caves – This allows them to feel secure and express their natural reclusive behaviors.
  • Offer new foods like bloodworms or black worms – The excitement of fresh treats keeps them active and engaged.
  • Rearrange decorations and plants – Change up their environment so it remains interesting and explorable.
  • Add bubble streams – Axolotls love playing in bubbles, an activity that relieves stress.

By offering a stimulating and varied home, your solo axolotl can thrive despite not having a tank mate.

Interact with Your Solo Axolotl Daily

Even though axolotls are not social with each other, they can form bonds with their human caretakers! Set aside 5-10 minutes each day to interact with your axolotl. You can:

  • Hand feed them treats like worms – This forms positive associations.
  • Pet their heads gently – Axolotls enjoy gentle tactile stimulation.
  • Hold them briefly – Only for short periods to avoid stress.
  • Make eye contact at eye level – Help them recognize you as their caretaker.

By taking time to interact with your solo axie daily, you become their social connection. This provides enrichment and mental stimulation needed for a solitary axolotl to thrive.

Conclusion

To sum up, axolotls are social by nature and can benefit from being kept in pairs or groups. However, with proper care and enrichment, solitary axolotls can lead full, healthy lives as well. When in doubt, opt for keeping just one axolotl, especially if tank space is limited.

Monitor any grouped axolotls for signs of aggression or stress. Whether you keep these fascinating amphibians alone or with tankmates, they are sure to bring you joy as unique aquatic pets.
