Axolotl Tank Set up - A Beginner’s Guide

Axolotl Tank Set up – A Beginner’s Guide


Axolotls require a specific habitat to live in captivity. Set up an Axolotl tank by starting with at least a 20-gallon tank. Use an effective filter to keep the water clean but ensure it doesn’t create a strong current.

Choose fine sand or smooth gravel for the bottom to avoid ingestion when the Axolotl eats. Cycle the tank to grow beneficial bacteria before adding the Axolotl.

Control the water temperature and pH to maintain a stable environment for Axolotl’s health.

Choosing the Right Tank

When choosing a tank for an Axolotl, a minimum size of 20 gallons is necessary for young Axolotls, and adults require a tank ranging from 30 to 40 gallons.

Axolotls need space for both their comfort and to maintain clean water, which is crucial for their health. Prefer a long tank over a tall one, as it provides more surface area for oxygen exchange and suits the Axolotl’s need to move around since they do not need deep water.

Water quality is of utmost importance, and a strong filtration system is required to manage the waste Axolotls produce. The filter should be capable of handling the tank’s bioload while avoiding strong water currents that can stress Axolotls.

The tank should have a secure lid to prevent escapes and potential injuries. Inside the tank, provide hiding places like caves for the Axolotl’s security, and ensure all decorations are smooth to prevent injuries.

Setting Up Filtration

To set up a filtration system for an Axolotl tank, select a filter that matches the tank size and the Axolotls’ bioload. Proper filtration maintains water quality, essential for Axolotl health. It removes waste, breaks down toxins, and sustains beneficial bacteria that aid the nitrogen cycle.

Consider the following when installing an Axolotl tank filter:

  • Filter Type: Use a filter suitable for the tank’s volume and Axolotl quantity. Canister filters are effective and have a high media capacity.
  • Flow Rate: Axolotls need a low water flow. Choose a filter with an adjustable flow rate to prevent stress.
  • Regular Maintenance: Clean filter media to prevent blockages and maintain efficiency.
  • Beneficial Bacteria: Cycle the tank before adding Axolotls to grow beneficial bacteria, using water conditioners to accelerate the nitrogen cycle.
  • Monitor Water Parameters: Test the water regularly to check if the filter keeps the environment stable, making adjustments as needed.

Use water conditioners when changing water to eliminate chlorine and chloramine, ensuring a safe habitat for Axolotls. Consistent maintenance and monitoring contribute to a clean and healthy environment for Axolotls.

Selecting Substrate and Decor

After setting up the filtration system, carefully select a suitable substrate and decorations for your Axolotls. The substrate should be smooth to avoid harming the Axolotl’s skin.

Fine sand is often used because it reduces the risk of impaction, which occurs when indigestible material accumulates in the Axolotl’s digestive system.

A tank without any substrate, known as a bare bottom tank, is another option that makes cleaning easier. For a more natural appearance, large, smooth rocks that cannot be swallowed can be chosen to avoid choking risks.

Decorations provide shelter and enrichment for Axolotls. They need hiding places to feel secure, similar to their natural habitat.

Adding rocks, caves, and safe artificial plants can improve their living space. Decorations must be free from sharp edges and small, ingestible parts, and should be cleaned and safe for aquarium use to prevent contamination of the water.

Water Parameters and Cycling

Establishing the proper water parameters and cycling the tank is essential for a healthy Axolotl environment. Axolotls are sensitive to changes and require controlled conditions.

Key factors to monitor include:

  • Temperature: Keep between 60°F to 72°F (15.5°C to 22.2°C) to reduce stress and minimize harmful bacteria and fungi.
  • pH Level: Maintain a slightly acidic to neutral range of 6.5 to 7.5.
  • Ammonia: Levels must be 0 ppm, as it is toxic to Axolotls.
  • Nitrites: Levels should also be 0 ppm for Axolotl safety.
  • Nitrates: Keep below 20 ppm to prevent stress and health problems.
  • Water Hardness: Aim for a general hardness (GH) of 7 to 14 dGH, which is soft to moderately hard.

Cycling the tank is necessary to establish beneficial bacteria that process waste and chemicals. Make sure the tank is ready for your Axolotls by cycling it with 0 ppm ammonia and nitrites and stable nitrates.

Introducing Your Axolotl

After the aquarium is cycled and stable, introduce the Axolotl to its new environment. The acclimation is essential for the Axolotl’s health, allowing it to adjust to the tank’s water and temperature.

Start by floating the Axolotl’s bag on the tank surface for 15 to 20 minutes to equalize the temperatures.

Then, slowly add small amounts of tank water to the bag every 5 minutes for an hour, helping the Axolotl adapt to the water chemistry. After acclimation, place the Axolotl in the tank without adding the bag’s water to avoid contamination.

The tank should have hiding spots and a sand substrate for the Axolotl’s comfort and safety. Look out for any signs of stress such as not eating or being inactive. Feed according to instructions and remove uneaten food to maintain cleanliness.

A properly acclimated Axolotl will show normal behavior and have a good appetite. With careful acclimation, the Axolotl should prosper in its new home.
