You’ve got a soft spot for axolotls, don’t you? They’re quirky, adorable, and full of personality. But when it comes to keeping them together, things can get a little tricky.
You might be wondering how many of these little guys can share the same tank without issues. Axolotls are unique in many ways, and their social needs are no exception.
If you’re ready to set up a harmonious tank for your pets, let’s break down everything you need to know about how many axolotls can live together comfortably.
Can Axolotls Be Kept Together?

Axolotls can live together, but it’s not as simple as tossing a few into a tank and calling it a day. They’re generally solitary creatures, but they can cohabitate under the right conditions. You’ll need to consider factors like tank size, age, temperament, and feeding habits before deciding how many can share a space.
Axolotl eggs typically hatch in about 2 to 3 weeks after being laid.
Axolotls are predatory by nature, which means they might nibble on each other if space is too tight or resources are scarce. If you’re housing multiple axolotls, it’s essential to create an environment where they feel safe and have enough room to spread out.
Why Space Matters for Axolotls
The size of your tank plays a massive role in how many axolotls can live together. These amphibians need plenty of space to roam and explore. A cramped tank increases stress, which can lead to aggressive behaviors like biting or even cannibalism.
- General rule of thumb: One axolotl needs at least 20 gallons of water. For each additional axolotl, add at least 10 more gallons.
- For example, a pair of axolotls should have a 30-gallon tank, while three axolotls will need 40 gallons or more.
Larger tanks give your axolotls enough room to establish their own territories and reduce the chance of territorial disputes.
Factors to Consider When Housing Axolotls Together
Let’s go beyond tank size and look at other key factors. These elements play a huge role in determining how many axolotls you can safely keep in one tank.
Age and Size of Your Axolotls
Axolotls of similar age and size are more likely to get along. Mixing juveniles with adults can lead to problems because the larger ones might see the smaller ones as food.
- Juveniles (under 6 months old): Best kept separately until they’re fully grown.
- Fully grown axolotls: Typically reach about 9-12 inches and are easier to house together if they’re similar in size.
A female axolotl can lay between 300 and 1,000 eggs during a single breeding season.
Always monitor their interactions, especially if one axolotl is significantly smaller than the others.
Temperament and Personality
Not all axolotls are the same. Some are naturally more aggressive, while others are laid-back. Before introducing new tank mates, spend time observing their behavior. If you have a particularly feisty axolotl, it might do better in a separate tank to avoid stressing out others.
Feeding Time Challenges
One of the biggest challenges when keeping multiple axolotls together is feeding time. Axolotls aren’t exactly polite diners. They’ll go for any moving object, including a tank mate’s foot or tail.
- Solution: Use feeding tongs to offer food directly to each axolotl. This ensures everyone gets their fair share without resorting to nipping.
- If aggression persists, consider feeding them separately to minimize stress and injuries.
Tank Setup for Multiple Axolotls
A well-designed tank can make all the difference when housing multiple axolotls. The goal is to create an environment that mimics their natural habitat and gives them enough space to avoid each other when needed.
Creating Hiding Spots
Axolotls love hiding, and having plenty of hiding spots can reduce tension in a shared tank. Use items like:
- Aquarium-safe caves
- PVC pipes
- Plants (real or fake)
These hiding places act as personal spaces where axolotls can retreat if they feel overwhelmed.
Maintaining Clean Water
Axolotls produce a lot of waste, and keeping their water clean is critical. When housing multiple axolotls, a strong filtration system is a must.
- Filters: Use a gentle, low-flow filter to avoid stressing your axolotls.
- Perform weekly water changes (20-30%) to maintain optimal water quality.
Test your water regularly to ensure ammonia, nitrites, and nitrates stay within safe levels.
Substrate Choices
The substrate in your tank matters too. Gravel can be dangerous for axolotls because they might accidentally swallow it while eating. Opt for sand or go with a bare-bottom tank for easier cleaning.
Adult axolotls typically grow to a length of 20 to 30 cm (about 8 to 12 inches).
Common Problems and How to Solve Them
Even with the best setup, problems can arise when housing multiple axolotls. Here are some common issues and how to address them.
Biting and Aggression
Biting usually happens when axolotls are stressed or feel crowded. If you notice frequent nipping:
- Upgrade the tank size to give them more room.
- Add extra hiding spots to reduce tension.
- Monitor feeding times closely to prevent competition.
Injuries and Missing Limbs
Axolotls have an amazing ability to regenerate lost limbs, but frequent injuries indicate something’s wrong. Check your tank setup, water conditions, and tank mate compatibility. If necessary, separate the injured axolotl to allow it to heal.
Stress and Poor Health
Signs of stress include a lack of appetite, gill shrinking, or unusual behavior. Stress often comes from overcrowding, poor water conditions, or aggressive tank mates. Address these issues immediately to keep your axolotls healthy.
Can You Mix Axolotls with Other Species?
While it’s tempting to add variety to your tank, axolotls don’t usually do well with other species. They’re best kept in species-only tanks for several reasons:
- Fish: Many fish will nip at axolotl gills, causing stress and injury.
- Shrimp and snails: These might seem like harmless additions, but axolotls may eat them.
If you’re set on adding other creatures, stick to species that won’t harm or stress your axolotls, and always monitor their interactions closely.
Tips for Keeping Multiple Axolotls Happy
- Start small: Begin with just two axolotls and see how they interact before adding more.
- Quarantine newcomers: Always quarantine new axolotls for at least 30 days before introducing them to your main tank.
- Observe regularly: Spend time watching your axolotls to catch any signs of stress or aggression early.
Keeping multiple axolotls can be rewarding, but it takes planning and effort to ensure they live harmoniously.
Wrapping It Up: A Peaceful Axolotl Tank
Setting up a tank for multiple axolotls is all about balance. Start with the right tank size, provide plenty of hiding spots, and monitor their behavior to ensure they’re comfortable.
By understanding their needs and staying attentive, you can create a peaceful home where your axolotls thrive. Ready to expand your axolotl family? Start small, keep it simple, and watch your quirky pets flourish together!
