You know that feeling when you want to create the perfect home for your axolotl? It’s not just about keeping them safe—it’s about making them happy, too.
A well-decorated tank isn’t just pretty; it’s essential for your axolotl’s health and comfort. From hiding spots to soft plants, the right decorations can make a huge difference.
So, how do you choose the best ones? Let’s talk about what works, what doesn’t, and how to create a tank your axolotl will love.
Choosing Decorations That Keep Axolotls Happy

Before picking anything for your tank, it’s good to know what axolotls need to feel comfortable. These little amphibians love hiding, resting, and exploring, but their delicate skin and gills mean that every decoration must be safe, soft, and non-toxic.
The absolute minimum tank size for one axolotl is 110 liters (approximately 29 gallons) to accommodate their needs and waste production effectively.
They’re curious, but they can’t tell what’s safe to touch, so it’s up to you to make the right choices.
Focus on Smooth and Non-Abrasive Materials
Axolotls are incredibly sensitive to sharp or rough surfaces. Decorations with jagged edges can damage their soft skin or delicate gills. Look for smooth surfaces and materials like:
- Resin or plastic decorations labeled safe for aquariums.
- Ceramic hides without rough edges.
- Soft silicone plants instead of hard plastic ones.
Avoid anything sharp, pointy, or that feels gritty to the touch. Even small scratches can cause big problems for an axolotl.
Prioritize Hiding Spots
Axolotls love hiding during the day. It makes them feel safe and secure. Without good hiding spots, they can get stressed, which isn’t good for their health. Caves and tunnels are some of the best choices for hiding spots, and they come in many designs to suit your tank. Popular options include:
- PVC pipes: Affordable and easy to customize.
- Ceramic caves: Smooth, safe, and available in natural shapes.
- Resin logs or rocks: These give the tank a natural look while providing shelter.
A 180-liter (about 40 gallons) tank is recommended for optimal health, providing ample space for swimming and reducing nitrate levels.
Make sure the entrance is wide enough for your axolotl to swim through comfortably but not so big that it doesn’t feel cozy.
Add Plants for a Natural Touch
Axolotls may not eat plants, but they love resting on them or swimming through soft leaves. Plants help create a calming environment and improve water quality by reducing nitrate levels. Both live and artificial plants can work, but each has its pros and cons:
- Live plants: Great for water quality but need proper lighting and care. Popular choices include Java fern, Anubias, and Marimo moss balls.
- Artificial plants: Low-maintenance and easy to clean. Choose soft, silicone-based plants that won’t scratch.
Place plants near hides or along the edges of the tank to create shaded areas where your axolotl can relax.
Decorations to Avoid
Not all decorations are safe for axolotls. Some can harm their skin, pollute the water, or even be swallowed accidentally. Avoid these common mistakes:
No Gravel or Small Substrates
Gravel might look nice, but axolotls often swallow it while eating. This can lead to blockages or impaction, which is dangerous and hard to treat. Instead, use:
- Fine sand: Gentle on their belly and much safer.
- Bare-bottom tanks: Easy to clean and free from swallowing risks.
Axolotls produce significant waste; thus, keeping nitrate levels below 20 ppm is crucial, which is easier in larger tanks.
Skip Sharp or Brittle Objects
Any decoration with sharp edges or made of brittle materials like glass is a no-go. These can break or chip, creating sharp pieces that might injure your axolotl. Stick to soft and smooth options for safety.
Avoid Painted or Coated Items
Paint can chip or leach chemicals into the water over time. Even aquarium-safe paints can wear down if the coating gets scratched. It’s better to stick with solid, natural materials or decorations made specifically for aquatic use.
Decorating for Function and Style
Axolotl tanks don’t have to be boring! You can create a beautiful setup that’s also functional. Start with a layout that mimics their natural environment and adjust based on their behavior.
Create Zones in the Tank
Divide the tank into sections to give your axolotl a mix of open space and cozy spots. For example:
- Resting areas: Place hides and caves in low-traffic corners.
- Exploration zones: Add plants and soft decorations they can swim through.
- Open swimming space: Leave a clear area in the middle for easy movement.
By balancing these zones, your axolotl will have everything it needs to stay active and relaxed.
Use Natural-Looking Decorations
Axolotls look stunning in tanks with a natural vibe. Decorations like driftwood, rocks, and aquatic plants create a habitat that feels like their wild environment. When using natural materials, make sure they’re:
- Aquarium-safe: Boil driftwood and rocks to remove bacteria or parasites.
- Stable: Secure heavy items to prevent tipping or shifting.
Adding natural touches not only benefits your axolotl but also makes the tank more visually appealing.
Light It Right
Axolotls prefer dim lighting, so avoid bright or harsh setups. Use low-intensity aquarium lights or add floating plants to diffuse the light. This keeps the tank comfortable while highlighting its beauty.

Maintaining Your Decorations
Decorations need regular cleaning to keep your axolotl safe and healthy. Dirty or algae-covered items can affect water quality. Here’s how to keep everything in top shape:
Regular Cleaning Routine
- Remove decorations weekly and rinse them in tank water (not tap water).
- Scrub algae gently with a soft brush.
- Boil natural items like driftwood every few months to prevent bacteria buildup.
Check for Damage
Inspect decorations often for chips, cracks, or sharp edges. Replace damaged items immediately to avoid accidents. Keeping everything in good condition helps maintain a safe environment.
Rearrange Occasionally
Axolotls enjoy exploring new setups, so changing the layout now and then can keep them entertained. Just make sure their favorite hiding spots stay accessible.
Creating a Safe and Fun Tank for Your Axolotl
Decorating your axolotl’s tank is more than just adding pretty things. It’s about building a home where they can thrive. By choosing safe, functional, and natural-looking decorations, you’ll create a space your axolotl will love.
Keep their needs in mind, and don’t be afraid to experiment with different setups. After all, a happy axolotl makes for a happy owner.
