How Big Does an Axolotl’s Tank Need to Be for Optimal Health and Happiness
If you’ve recently welcomed an axolotl into your home or are thinking about getting one, you’re probably wondering how much space your new pet will need.
After all, they may look small, but they can be surprisingly active and need plenty of room to swim around. A cramped tank could lead to stress, health problems, and a sad axolotl.
In this guide, we’ll cover exactly how big an axolotl tank should be, how to set it up, and what other factors you need to keep in mind to make sure your axolotl has a happy, healthy life.
Axolotls’ Space Needs
You might be tempted to think a small tank will work just fine for your axolotl. After all, they’re not big creatures. However, they need room to roam and grow, just like any pet. The size of their tank plays a huge role in their well-being. Here’s what you need to know about how much space they really need.
Current estimates suggest that fewer than 1,000 axolotls remain in the wild, leading to their classification as critically endangered by the IUCN since 2006.
Minimum Tank Size
For one axolotl, the minimum tank size should be 20 gallons (about 75 liters). While this might seem small, it’s just enough to allow your axolotl to move around and stay healthy. For every additional axolotl, you’ll need to add at least 10 gallons to the tank.
Think about it: axolotls grow to be around 8 to 12 inches long, and they love to swim in all directions. A 20-gallon tank gives them the freedom to do just that without feeling cramped.
Larger Tanks Are Better
While a 20-gallon tank is the minimum, bigger is always better. If you have the space, opt for a 30-gallon tank or larger. A larger tank gives your axolotl more room to move and can help you maintain better water quality, which is crucial for their health.
Plus, if you ever decide to add more axolotls or other tank mates in the future, a larger tank will give them all the space they need.
Why Tank Size Matters for Your Axolotl’s Health
Tank size isn’t just about how much room your axolotl has to swim; it impacts their health and behavior too. When an axolotl feels cramped, they can experience stress, which might lead to poor appetite, slower growth, or even illness. Here’s why it’s important to provide them with plenty of space:
Stress Reduction
Axolotls, like many aquatic animals, are sensitive to their environment. If they don’t have enough room, they might feel stressed and anxious. This can show up in signs like hiding too much, losing their appetite, or becoming lethargic. A bigger tank can help them feel more at ease and avoid these stress-related issues.
Female axolotls can lay between 300 to 1,000 eggs during mating season, which occurs from March to June.
Cleaner Water
In a cramped tank, waste products from your axolotl (like ammonia and nitrates) can build up quickly. This can cause poor water quality, which is harmful to your axolotl. A larger tank gives you more space to install a better filtration system and keep the water cleaner for longer, benefiting both you and your pet.
Shape of the Tank: What Works Best for Axolotls?
When it comes to choosing the right tank, size is important, but so is the shape. Axolotls are bottom-dwelling creatures, which means they spend most of their time near the tank floor. They also need enough space to swim freely in all directions.
Long Tanks vs. Tall Tanks
For axolotls, long tanks (those with a greater length than height) are preferred. A long tank gives them more swimming space horizontally, which is ideal since axolotls aren’t great swimmers in deep water. They need room to move from one end of the tank to the other.
Tall tanks can be tricky because axolotls don’t swim up and down the way fish do. A tall tank often just wastes space, making it harder for your axolotl to access the full tank area.
Tank Dimensions to Consider
When looking for the right tank, aim for something with dimensions like:
- 30 gallons: Around 36” long x 12” wide x 16” tall
- 40 gallons: Around 36” long x 18” wide x 16” tall
- 55 gallons: Around 48” long x 13” wide x 21” tall
These sizes give your axolotl plenty of swimming space, while also allowing you to maintain a stable environment in terms of water quality.
Adult axolotls measure between 6 to 18 inches in length and weigh between 2 to 8 ounces.
Keeping Multiple Axolotls Together: Space Considerations
If you plan to keep more than one axolotl, you’ll need a larger tank. Axolotls can live together, but they need enough space to avoid territorial behavior or aggression. This can be tricky, especially when they’re young, as they may mistake each other for food.
Space per Axolotl
As mentioned earlier, you’ll need to add 10 gallons for every additional axolotl. So, if you have two axolotls, a 30-gallon tank should be your minimum. For three axolotls, a 40-gallon tank is ideal.
Risk of Aggression
In crowded tanks, axolotls may become more aggressive. They might bite each other, especially if they’re competing for food or space. To avoid this, provide plenty of hiding spots and areas where each axolotl can retreat if they want to be alone.
Other Key Factors to Consider When Setting Up Your Tank
While tank size is crucial, there are a few other factors that will affect your axolotl’s health and happiness.
Water Temperature
Axolotls are cold-water creatures, so they don’t need a heated tank. In fact, keeping the water too warm can lead to stress and health issues.
The ideal water temperature for axolotls is 60-64°F (15-18°C). Avoid placing your tank in direct sunlight or areas with fluctuating temperatures, as this can heat up the water too much.
Filtration System
A good filtration system is important, especially in larger tanks. Axolotls are messy eaters, and they produce a lot of waste. A filter will help maintain water quality by removing toxins like ammonia, nitrites, and nitrates.
However, be cautious about the strength of the filter’s current. Axolotls are slow swimmers and don’t like strong currents. A filter with an adjustable flow rate will give you control over the water movement.
Substrate Choices
The type of substrate you use in your tank can also affect the space and comfort of your axolotl. Avoid using small gravel or rocks that could be swallowed by your axolotl, leading to potential blockages.
Bare-bottom tanks or sand substrates are popular choices because they’re easier to clean and safe for your axolotl.
Decorations and Hiding Spots
Providing your axolotl with hiding spots is crucial for their well-being. They like to have places to retreat to, especially when they feel stressed or during molting. Include things like caves, PVC pipes, or plants that can create cozy hideouts.
Make sure to avoid sharp or rough decorations that could harm your axolotl’s sensitive skin. Smooth, soft decorations and plants work best.
Setting Up Your Axolotl’s Tank: Step-by-Step
Now that you know the size and shape of the tank, it’s time to set it up. Here’s a quick step-by-step guide:
- Choose a suitable tank: Aim for at least a 20-gallon tank for one axolotl. If you’re keeping multiple axolotls, go bigger.
- Add a filtration system: Pick one that’s not too powerful, and adjust the flow rate if needed.
- Set the substrate: Bare-bottom tanks are easy to clean, but sand or smooth rocks are acceptable too.
- Install decorations: Add hiding spots, plants, or smooth decorations for enrichment.
- Check water temperature: Keep the water cool, ideally between 60°F and 64°F.
- Cycle the tank: Before adding your axolotl, let the tank filter and stabilize for at least a week to ensure the water is safe.
- Monitor water quality: Regularly test for ammonia, nitrites, and nitrates. Make water changes as needed.
Conclusion: Bigger Tanks Lead to Happier Axolotls
Your axolotl deserves a spacious, comfortable home. The right tank size not only allows them to swim freely but also helps keep the water cleaner and reduces stress. Always aim for at least a 20-gallon tank for one axolotl, and consider a 30-gallon tank or larger for multiple axolotls.
By giving your axolotl a bigger tank, you’re ensuring they’ll live a longer, healthier life. Remember, bigger is always better when it comes to axolotls. The extra space allows them to thrive, and that’s what every axolotl owner wants. So, don’t skimp on the size—your axolotl will thank you for it.
