Creating a suitable environment for an axolotl is not just a matter of filling a tank with water. The layout of the aquarium plays a key role in its well-being, health and even behaviour. But should you choose natural plants or a more mineral setup with rocks and artificial hides? Here’s a complete overview of the advantages, drawbacks and recommendations.

Understanding an Axolotl’s Needs

The axolotl is a calm, low-activity animal that appreciates hiding spots, dim areas and a stable environment. It is sensitive to stress, bright lighting, sudden movements and frequent changes in its surroundings. A good setup should therefore provide:

• Shaded or sheltered areas
• Hiding places (half pots, caves, roots, etc.)
• Good water circulation with no strong current
• A clear bottom surface (axolotls like resting on the ground)

Mineral Décor: Simple, Stable, Effective

Mineral décor is often preferred by beginners. This includes non-living elements such as stones, driftwood, ceramics, clay pots or resin caves. This type of setup offers several advantages:

Advantages

• No specific maintenance required
• No risk of rot or plant pests
• Very stable over time (no growth or lighting requirements)
• Easier control of water quality

Drawbacks

• Less natural or visually appealing
• Can cause more stress if the tank looks too empty or too “hard”
• Some decorations may leach harmful substances if not aquarium-safe

Natural Plants: Aesthetic, but Technical

Aquatic plants bring colour, life and help maintain biological balance (nitrate absorption, oxygenation, etc.). They also provide shade and resting areas for axolotls. However, adding plants requires some precautions:

Which Plants to Choose?

Axolotls do best with hardy plants that grow slowly and tolerate cooler temperatures (16–20 °C / 60–68 °F). Good options include:

• Anubias: very resistant, easy to attach to a rock
• Java moss: grows in low light, creates hiding spots
• Cryptocoryne: broad leaves that help reduce light
• Elodea: a floating plant that helps oxygenate the water

Points of Caution

• Avoid fragile or fine-leaf plants: axolotls may uproot them easily
• No rich nutrient substrate: it can cause nitrate spikes
• No CO₂ systems or intense lighting: axolotls prefer dim tanks

Plants vs Mineral Décor: What to Choose?

There is no single answer—it’s more a matter of balance and personal preference. Here are some typical setups:

• Beginner wanting simplicity: mineral décor only, with hides and shaded areas
• Those who want a nicer tank + basic experience: add a few hardy plants (anubias, moss) attached to rocks or wood
• Experienced hobbyist: create a “low-tech” aquascape tailored to axolotl needs

A Hybrid Tank: The Best of Both Worlds?

Many keepers choose a mixed setup: mostly mineral décor with a few hardy plants attached to rocks or driftwood. This offers the benefits of both approaches:

• Environmental stability
• Natural, pleasing aesthetics
• Shaded, comfortable resting areas
• Less maintenance than a heavily planted tank

Conclusion

An axolotl doesn’t need a lush underwater garden to thrive. What it truly needs is a calm, secure environment with minimal stress. Whether you choose a mineral setup or a planted aquarium, the key is to respect its specific requirements regarding light, temperature and hiding places. A well-designed tank will be beneficial for your axolotl—and enjoyable for you to observe every day.
