What Size Tank Does an Axolotl Need for a Happy, Healthy Habitat?

If you’re planning to keep an axolotl, you’ve probably wondered what size tank they need. It’s a big decision because your axolotl’s comfort and health are directly tied to the space they live in.

Axolotls can grow pretty large, and their tank needs to accommodate that. But how big should it be? Too small, and you might end up with a stressed-out axolotl.

Too big, and it can be harder to manage the water quality. Let’s break it down so you can give your axolotl the perfect home!

The Right Size for Your Axolotl

When choosing a tank for your axolotl, the first thing to consider is their adult size. Axolotls typically reach about 9-12 inches in length when fully grown, though some may grow even bigger.

Axolotls can live between 10 to 15 years in the wild, showcasing their longevity among amphibians.

With that in mind, the general rule is to provide at least 10 gallons of water per axolotl. The more space, the better, as this gives them room to swim and explore.

Tank Size for One Axolotl

If you’re only keeping one axolotl, a 20-gallon tank is usually considered the minimum size. This size gives your axolotl enough room to move around without feeling cramped. A 20-gallon tank allows space for hiding spots, plants, and other essentials like a filter and heater, without crowding the creature.

If you have the space and resources, going larger—say, 30 gallons—is even better. More water means more stable water conditions, which is essential for axolotls, as they’re sensitive to changes in their environment.

Tank Size for Multiple Axolotls

If you plan on keeping more than one axolotl, you’ll need to think about the extra space. For two axolotls, you should consider a 30-gallon tank as the starting point.

Each additional axolotl should add at least 10 gallons of space. So, a tank for three axolotls should be around 40-50 gallons, and for four axolotls, aim for a 60-gallon tank.

Pro tip: Axolotls can sometimes be territorial. Keep an eye on their behavior, as one might try to claim more space than the other, which could lead to stress or even injury.

Why Tank Size Matters for Axolotls

Axolotls are aquatic creatures, but they aren’t just any fish. They need more than just water; they need enough space to roam, hunt, and hide. A larger tank helps with several important things:

• Better water quality: A larger volume of water dilutes waste, which makes it easier to keep the water clean.
• Space for natural behaviors: Axolotls like to explore, swim, and hide. A bigger tank gives them room to do all of that.
• Less stress: When an axolotl feels crowded, they can become stressed, which affects their health and behavior.

Choosing the Right Shape Tank

The shape of the tank is just as important as the size. While a tall tank might look appealing, it’s not ideal for axolotls. Axolotls are more comfortable in tanks with a longer horizontal space rather than tall vertical space.

Female axolotls can lay between 300 to 1,000 eggs during mating season, which occurs from March to June.

Long vs. Tall Tanks

• Long tanks (20 gallons long or 30 gallons long): These are the best option for axolotls. They give your pet plenty of room to swim across the bottom.
• Tall tanks: While these are often sold in pet stores, axolotls aren’t natural swimmers in the vertical plane. Tall tanks tend to waste space and don’t provide enough usable area for your axolotl to explore.

If you’re unsure about what shape to pick, always go for a long tank. This gives your axolotl more horizontal swimming space, which they’ll appreciate.

Setting Up the Tank

Now that you know the right tank size, it’s time to think about how to set it up. The environment inside the tank is just as important as its size.

Substrate

Axolotls can be sensitive to the substrate you choose for the tank floor. Avoid gravel or small rocks as they can be ingested, leading to health problems. Instead, opt for fine sand or a bare-bottom tank. Both of these options are safe and easy to clean.

Filtration

Axolotls are sensitive to water quality, so a good filtration system is crucial. While they don’t need powerful filters, you do need something that will help keep the water clean. A sponge filter is a great choice because it provides gentle filtration and doesn’t create strong water currents, which could stress your axolotl.

Temperature and Heater

Axolotls prefer cooler water, around 60°F to 64°F (16°C to 18°C). If you live in a warmer climate, a water chiller might be necessary. Make sure the tank doesn’t exceed 68°F (20°C), as higher temperatures can cause stress and health issues for your axolotl.

Water Quality and Maintenance

Water quality is the number one priority when keeping axolotls. Poor water conditions can lead to illness, infections, and even death. Keeping the water clean means regular water changes, checking the filter, and making sure the pH level is just right.

Filtration and Water Changes

Even with a good filter, you’ll need to perform regular water changes. Aim for a 20-30% water change once a week to keep things fresh. If your axolotl’s tank is on the smaller side, you might need to change the water more often.

In 1998, there were approximately 6,000 axolotls per square kilometer in Xochimilco; by today, this number has plummeted to just 35.

Testing the Water

Use a water test kit to check the pH, ammonia, nitrite, and nitrate levels. Axolotls are sensitive to these factors, so testing frequently is key. The pH should stay between 6.5 and 7.5, and ammonia/nitrite levels should always be at 0. Nitrates should be under 20 ppm.

Adding Decorations and Hiding Spots

Axolotls are shy creatures and need places to hide. Adding decorations and plants can help them feel more secure. Here are a few ideas:

• Caves or PVC pipes: These give your axolotl a dark, sheltered space to retreat to.
• Live plants: Adding plants to the tank will mimic their natural environment. Be sure to choose plants that are safe for axolotls, like anubias, Java moss, or elodea.
• Rocks or driftwood: These can provide hiding spots and offer some variety to the environment.

Just make sure any decorations are smooth and free of sharp edges that could harm your axolotl.

Monitoring Your Axolotl’s Behavior

Even with a perfectly sized and set-up tank, you need to keep an eye on your axolotl. Here are a few signs that your axolotl might be stressed due to tank size or environment:

• Lethargy: If your axolotl is staying in one spot or seems uninterested in moving, they may be stressed or uncomfortable.
• Scratching or rubbing against objects: This could indicate that your axolotl is having trouble adjusting to their environment.
• Aggressive behavior: If you have more than one axolotl, watch for signs of aggression, such as biting or chasing.

What to Do If Your Axolotl Is Stressed

• Check the water: Ensure the water quality is optimal, as poor conditions are a common cause of stress.
• Increase hiding spots: More places to hide can help your axolotl feel safer.
• Consider a larger tank: If your axolotl is outgrowing their space or acting stressed, upgrading to a larger tank can help.

Axolotl Tank Size Summary

To sum up, the size of your axolotl’s tank is crucial to their health and well-being. Here’s a quick breakdown:

• One axolotl: At least a 20-gallon tank; 30 gallons is even better.
• Two axolotls: A 30-gallon tank.
• Three axolotls: 40-50 gallons.
• Four axolotls: Around 60 gallons or more.
• Shape matters: Long, horizontal tanks are best.

Keep the Tank Clean

Regular water changes, using a good filter, and keeping the water temperature in check are essential for your axolotl’s health.

Create a Comfortable Environment

Provide plenty of hiding spots, plants, and smooth decorations to give your axolotl a stress-free environment. Always monitor their behavior to make sure they’re happy and healthy.

Creating the Ideal Home for Your Axolotl

Choosing the right size tank for your axolotl is just the start. By providing a proper tank setup, maintaining water quality, and monitoring your axolotl’s behavior, you’re setting the stage for a happy, healthy pet. Keep these tips in mind, and you’ll be giving your axolotl the perfect home they deserve!
