Don’t keep axolotls in a tank with other fish or species. Axolotls may try to eat smaller fish, and larger animals could get aggressive with your axolotls.
Sunlight can also heat your tank and stress out your axolotls.
Sand or rock substrates can be purchased from your local pet or aquarium store. Fine aquarium sand is small enough to pass through the axolotl’s digestive system without causing any harm. Don’t leave the bottom of your tank bare since axolotls cannot grip glass easily and may become stressed.
If you can’t a filter with a slow current, put aquatic plants in front of it to lessen the flow
Dechlorinating agents can be purchased from your local pet store or online.
If your tank didn’t come with a mesh lid, check your local pet store or online for one.
Provide multiple hiding places if you’re housing more than 1 axolotl. Each axolotl should have its own place to hide.
Plants like Java ferns can be anchored to decorations, such as large rocks or driftwood. If you don’t want to care for or prune aquatic plants, use artificial plants instead. Put your plants in front of your filter if it has a strong current.
Adding decoration to your tank is optional.
Keep a thermometer in your axolotl tank so you can check the temperature at a glance. Axolotls can handle temperatures as low as 40 °F (4 °C).
Water siphons can be purchased from your local pet store.
If you need to perform a water change on the same day, use a dechlorinating agent in your tap water.
Make any pH adjustments slowly so you don’t shock your axolotls. After you make a pH adjustment, check the levels again the following day to see how it has changed.
