Tank Size: Axolotls require ample space to swim and explore. A larger tank is always better, providing more floor space for them to move around. A 20-gallon tank is the minimum recommended size for a single adult axolotl, but if possible, opt for an even larger tank to provide a more comfortable environment.

Water Temperature: Axolotls are cold-water species, and maintaining the right temperature is crucial for their well-being. Keep the tank water between 60°F and 68°F (15°C and 20°C). You can use a reliable aquarium heater or adjust the room temperature to achieve the desired range. Avoid exposing the tank to direct sunlight or placing it near heat sources or cold drafts.

Filtration System: Axolotls are sensitive to high ammonia and nitrite levels, so a proper filtration system is vital. Consider using a sponge filter or another filter that provides gentle water flow. Strong currents can stress axolotls, so ensure the filter is adequately sized for the tank and doesn’t create a turbulent water environment.

Substrate: When choosing a substrate for your axolotl tank, use a bare bottom or a fine sand substrate. A bare bottom tank makes it easier to maintain cleanliness and prevents the axolotls from accidentally ingesting small particles. If you prefer a more natural look, use fine sand that doesn’t contain sharp edges or small rocks. Avoid gravel, as it can cause digestive issues if swallowed.

Live Plants: Adding live plants to the axolotl tank enhances its aesthetics and provides additional benefits. Live plants help maintain water quality by absorbing nitrates and providing oxygen. They also offer hiding spots for the axolotls, reducing stress and creating a more natural environment. Choose aquarium plants that can tolerate cold water and won’t be uprooted easily.

Hiding Places: Axolotls are social animals that appreciate having hiding places in their tanks. Provide them with PVC pipes, caves, or other suitable structures where they can retreat and feel secure. These hiding spots mimic the natural habitat of axolotls, helping them feel more comfortable and safe.

Water Quality and Maintenance

Maintaining clean and healthy water is crucial for the well-being of your axolotls. Here are some important points to keep in mind:

Water Chemistry: Regularly test the water parameters, including pH, ammonia, nitrite, and nitrate levels. Axolotls prefer slightly alkaline water with a pH range of 7.4 to 7.6. Use appropriate water testing kits to monitor the water chemistry and make necessary adjustments.

Water Changes: Perform regular water changes to keep the tank water clean and toxins-free. A 20% to 25% water change every week is recommended. During water changes, use a siphon to remove uneaten food, waste, and debris from the bottom of the tank.

Dechlorination: Tap water often contains chlorine and chloramines, which are harmful to axolotls. Before adding tap water to the tank, treat it with a water conditioner specifically designed to neutralize these chemicals. Follow the instructions provided by the manufacturer to ensure the correct dosage.

Cycling the Tank: Before introducing your axolotls to a new tank, it’s crucial to cycle it properly. Cycling establishes beneficial bacteria that break down toxic ammonia into less harmful substances. Use a reliable source of ammonia, such as pure ammonium chloride, or consider using a bacterial supplement to kick-start the cycling process. Monitor the water parameters during cycling and ensure ammonia and nitrite levels reach zero before adding axolotls.

Feeding and Nutrition
