Thinking of adopting an axolotl? Before welcoming this fascinating amphibian, it is essential to prepare its future habitat. Contrary to what many believe, a simple tank filled with water is not enough. A stable and well-planned environment ensures your axolotl’s health and longevity. Here is everything you need to include in a complete starter kit.

The Aquarium: the Foundation of Comfort

An adult axolotl requires a minimum volume of 60 to 80 litres, but the larger the tank, the better. Choose a long aquarium rather than a tall one, as axolotls mostly swim horizontally.

Make sure the aquarium:

• Is made of glass (plastic is not ideal long term)
• Has a lid (axolotls can jump… even if it is rare)
• Has a stable base and is protected from vibrations

A Good Filter — but Not Too Strong

A filter is essential to maintain clean and stable water. However, axolotls dislike strong currents. Choose:

• An adjustable internal filter or an external filter with moderate flow
• An outlet directed toward a wall or softened by a plant or decoration

Sump filters or waterfall filters are often too turbulent for axolotls.

The Substrate: Pay Attention to Risks

To avoid accidental ingestion of gravel, choose:

• A bare-bottom tank (very easy to clean)
• Or fine aquarium sand (such as Loire sand)

Round or large gravel pieces can be swallowed and cause fatal intestinal blockage.

Heating: Often Unnecessary

Axolotls prefer cool water between 16 and 18 °C. A heater is therefore not needed unless temperatures drop for long periods (<14 °C). However, if your home is too warm in summer, a cooling system (surface fan or aquarium chiller) may be useful.

Lighting: Soft and Optional

Axolotls dislike bright lighting. If you install plants, soft LED lighting can be used. Otherwise, prefer indirect or ambient room light.

Hiding Spots: Essential for Stress Reduction

Axolotls need to feel safe. Provide several hiding spots:

• Drilled coconut shells
• Clay pots laid on their side
• Large-leaf natural or artificial plants
• Resin caves with smooth edges

Thermometer and Water Test Kits

A floating or digital thermometer is essential to monitor daily temperature. For water quality, test regularly for:

• pH (target: 6.5 to 8)
• Nitrites (must remain at 0)
• Nitrates

Net, Siphon and Maintenance Tools

For proper tank maintenance, prepare:

• A fine-mesh net
• A gravel vacuum / siphon to remove waste
• A dedicated bucket (never use a household bucket with chemical residue)

And for the Axolotl Itself?

Once your tank is cycled (minimum 4 weeks with nitrogen cycle monitoring), you can welcome your axolotl. Remember to:

• Acclimate it slowly to the aquarium temperature
• Monitor it during the first hours
• Avoid unnecessary handling

Estimated Budget for a Basic Starter Kit

Here is a general price estimate:

• 60 L aquarium: €60 to €100
• Filter: €20 to €40
• Fine sand or décor: €15 to €30
• Hiding spots: €10 to €20
• Water tests and thermometer: €15 to €25

A complete kit therefore costs around €120 to €200 (excluding the animal).

Conclusion

Welcoming an axolotl is not something to improvise. A good starter kit ensures optimal living conditions from the beginning. By investing in the right equipment, you reduce the risks of disease, stress or premature death. It is far better to prepare everything in advance and wait a few weeks than to rush. Your axolotl will thank you — in its own way.
