When I first started keeping axolotls, I didn’t realize how important it was to truly understand what these amazing pets need to thrive. Axolotls, often called Mexican walking fish, are actually a type of salamanders and a fascinating species loved by many aquarium enthusiasts.
Over time, I began to explore different ways to create the perfect tank setup and learned which components were really essential. From water temperature to hiding spots, every little detail you provide affects how healthy and happy your axolotl is. That’s why in this blog, I’m sharing what I’ve learned to help others who are thinking of keeping axolotls as pets too.
what do axolotls need in their tank – Answer
To help axolotls thrive, they need a well-maintained tank with clean, filtered water (60–72°F), a suitable filtration system, safe substrate like sand or large rocks, decorations and plants for hiding and exploring, and gentle lighting to observe them and support water quality.
Water Quality
If you want your axolotls to stay healthy, you need to treat them like the aquatic animals they are and focus on the essential things that matter most—starting with water quality. Their tank needs to be clean and stable, with a constant temperature between 60 and 72 degrees Fahrenheit, which helps them stay calm and active.
I always make sure the water is filtered to remove any debris, excess food, and harmful chemicals. To really maintain the right balance, I also perform regular water changes, which makes a huge difference over time. Doing all this keeps their little world safe and helps them thrive.
Filtration System
To keep my axolotl tank in top shape, I learned that a proper filtration system is absolutely essential. The filter must be suitable for the size and volume of the tank, and it should be strong enough to handle the amount of water, especially if you’re keeping a larger number of axolotls.
I always choose one that’s appropriate and easy to cleaned so I can do it regularly. That way, the water quality stays steady, and I can maintain good parameters without stress. Water changes are also a great way to ensure everything stays balanced and safe.
Substrate
I always make sure to use a suitable substrate at the bottom of my axolotl tank to provide a safe and comfortable environment. The surface must be smooth, not rough, because anything sharp can damage their delicate skin.
I’ve found that fine sand, a bare bottom, or large rocks (at least 3x the size of the axolotl’s head) really helps ensure there’s no choking hazard. I strongly discourage using pebbles or any small unsecured bits, since they can cause impaction, and that can be deadly.
Decorations and Plants
My axolotls really enjoy having different places to hide and explore, so I always think it’s a good idea to provide the right decorations and plants in their tank. I usually include things like rocks, caves, and both live and artificial plants to make the space feel natural.
But it’s super important to choose items that are safe, because some decorations might release harmful chemicals into the water, which can be dangerous.
Lighting
While axolotls don’t require special lighting, it’s still a good idea to provide enough light in their tank so you can observe them easily and help maintain the water quality. I use a suitable light source like an LED or fluorescent bulb, which gives just the necessary glow without stressing them.
Since they also enjoy places to hide and explore, I make sure the light isn’t too strong and that there are decorations, plants, and caves they can chill under. You can include live or artificial plants, but it’s important to choose ones that are safe and won’t release harmful chemicals into the water—that’s something I learned the hard way with a plastic plant once!
Conclusion
To help your axolotls truly thrive, it’s important to build a well-maintained tank that covers every need. Start with good water quality and a suitable filtration system, then add an appropriate substrate that’s safe and easy to clean.
Don’t forget the fun stuff—decorations and plants not only make the tank look nice but also give your pet places to explore. Use adequate lighting to keep the tank visible and balanced. By providing these essential components, you’ll create a healthy, comfortable environment that will keep your axolotl both happy and active.
Faqs
Do axolotls need anything in their tank?
When setting up an aquarium for axolotls, it’s really important to add decorations with smooth edges to protect their delicate skin and gills. They also need strong filtration to keep the water clean, but they prefer an overall low flow, so they don’t get stressed by strong currents.

What do you put in an axolotl tank?
For my axolotls, I’ve found that adding a mix of silk plants, live plants, rock hides, and driftwood works really well. PVC pipes are also great for giving them tunnels to explore, and even terracotta pots are totally fine as cozy hiding spots. These things make the tank feel more natural and keep them happy.
What do axolotls need for beginners?
If you’re new to keeping axolotls, make sure their tank has the optimum environmental temperature between 16-18°C, and it should never exceed 24°C. The ideal water pH is around 7.4–7.6, which helps them stay stable. Tap water often contains chlorine, which is harmful, so a de-chlorinator must be used, or let the water stand for 24 hours before adding it to the tank.
