Axolotl Temperature (Tips to Maintain an Ideal Temperature)

For a species of animal that can live both on land and in water, maintaining an ideal aquarium temperature can be challenging. The axolotls are amphibians which means that they have both gills and lungs with which they can breathe. 

Usually, when amphibians are young, they live underwater and have gills with which they breathe, but as adults, they lose their gills, develop lungs, and can live on land. 

However, axolotls cannot live outside of the water and are rarely seen outside of the water for an extended period; it is simply not natural for them to do so. 

Therefore, being primarily aquatic animals, what is the best temperature to keep them? Since axolotls live in cold water lakes in the Mexican valley, their ideal water temperature is 60-64° F. 

Temperatures of 75° F or higher can be life-threatening to your axolotls, so keep an eye on the water temperature. We recommend using an aquarium thermometer for convenience. 

Read on to learn more about caring for your pet axolotl with the ideal temperature.

Are Axolotls Sensitive to Temperature Changes?

Yes, since they are cold-blooded, axolotls are sensitive to temperature changes in their environment, especially to large temperature fluctuations over a short period.

This means that while they can tolerate a gradual, uniform temperature change over a long period, a sudden temperature change is definitely going to affect their health. 

For example, axolotls do well in temperatures between 60° F – 64° F (16° C to 18° C). Hence, a fluctuation between 16° C and 19° C over a 24 hr period is not too noticeable and is tolerable.

But a change from a 17° C straight to 20° C would probably come as a bit of a shock to the animal. Hence, causing stress and subsequently some health issues.

Axolotl Temperature Range

For axolotls, keeping them in an aquarium with a water temperature range between 50 -70 degrees Fahrenheit (between 10 – 20 degrees Celsius) is essential. However, the ideal temperature range is between 60-64 degrees Fahrenheit (16 and 18 degrees Celsius). 

That said, gradual or steady fluctuations within these ranges will not cause any harm to your animal. This is because axolotls need ample time to adjust their bodies to changes in temperature. 

This also explains why a sudden temperature change always poses a health threat to them. 

Therefore, consider buying an aquarium chiller if you’re experiencing a high, frequent, or sudden change in water temperature. Also, note that a too high water temperature measuring over 75° F (24° C) will lead to heat stress, loss of appetite, and even death.

What Temperature Is Too Hot for Axolotl?

Axolotls are some remarkable animals that love cool water. The maximum temperature for captive axolotls is 72 degrees Fahrenheit (22 degrees Celsius). Temperatures above 75° F are too hot and can cause heatstroke. 

Signs of heatstroke include loss of appetite, floating on the surface of the water, swelling, and many more.

Although keeping an axolotl’s tank cool is essential for its health, keeping it too cold might cause behavioral changes such as sluggishness and a slower metabolic rate (induced hibernation). 

On the other hand, the tank being a bit too cool isn’t nearly as hazardous as being too hot. As stated earlier, keeping your axolotls at consistently higher temperatures will lead to heat stress, loss of appetite, and death. 

But this does not mean that your axolotl is going to die right away within a month or two of living in a hot tank. In fact, some axolotls have even been reported to live far into adulthood at higher temperatures.

Now that you know the dangers of keeping your captive axolotls in consistently hot or fluctuating temperatures, what should you do to avoid heat stress or heatstroke? 

Below are a few tips you can implement to keep your axolotls’ tank cool all year round, especially in warmer months.

  • Keep your axolotl’s tank in a cool place. There should be a room or spot in your house that is visually appealing and, at the same time, cool enough for you to keep your axolotl’s tank. 

Avoid keeping it near windows, direct sunlight, or any heat-generating appliances, as these can increase evaporation and heat in the tank.

  • Use cold water. You can place frozen water bottles in the tank or some ice cubes to keep the water cool. 

However, one disadvantage of using this method is that, between when the ice cubes or frozen water bottle gets melted to when you change it to put another one, the temperature will drop (fluctuates), leading to stress if it happens over and over again. 

To avoid this, you must ensure that you add more ice cubes/frozen water bottles to the tank even before the first one gets thawed.

  • Use a mesh lid. Using a mesh lid allows water to evaporate and cool down the tank.
  • Use an aquarium fan. Typically, this is a small fan above your pet’s tank that blows some amount of cool air to the tank. The idea is to let the fan blow the surface of the water as much as possible. 

This will help the warm air (heat) dissipate from both the tank, water, and the air in the tank. A small ceiling fan or table fan is fine, but not a fan with a built-in cooling unit. This can make the tank too cold.

  • Use aquarium chillers. This should be your final resort. That is, if other methods didn’t work for you or if they were too demanding. 

Although aquarium chillers are expensive, they are one of the sure-fire ways you can keep your axolotl tank cool all year round, especially in warmer months.

This works by chilling the water first before sending it to the tank. This way, you can be sure of steady cool water.

What Temperature Is Too Cold for Axolotls?

Your axolotls will be fine in chilly water as long as the water isn’t frozen. However, the colder the water, the less active they will be. That said, the minimum water temperature you should keep your axolotl is 50 degrees Fahrenheit (10 degrees Celsius). 

Temperatures below 50 F are too cold. When axolotls are too cold, they slow down important metabolic functions such as digestion. Since they do not hibernate, the water temperature will need to be restored so they can eat, digest foods, and poop.  

If your axolotl lives for more than 20 days at 4° C, it can cause health issues.

Signs that your axolotl is too cold include lethargy, reduced appetite, reduced metabolism, and may even be forced to hibernate (that is, shuts down some functions entirely to reduce energy requirements).

Nonetheless, one thing you should take note of is that axolotls can even benefit from cold temperatures. Infection-causing bacteria and fungi reproduce more slowly when exposed to cold. 

This way, the immune system of the axolotl has a little more time to build up a defense against the virus as a result. Because of this, “fridging” is a common treatment for minor infections.

So if your axolotl gets too cold and slows or shuts down some “body functions,” what should you do? Here is a tip:

You can raise the water temperature by using an under-tank heater. However, ensure that the heater doesn’t overheat the tank. Once the water temperature returns to normal, you can discontinue using the heater.

It is vital to know the ideal temperature for your axolotl since the temperature will significantly impact the overall health and wellness of your pet. 

Axolotls are cold-blooded, so the temperature of their environment determines their body temperature. They will require a water temperature that is around 60 degrees to thrive. 

Maintaining the ideal temperature is a crucial step in creating a healthy habitat for your axolotls. A good way to check this is by using a digital thermometer. 

If you find that the temperature of your tank is significantly lower than the ideal range (that is to almost a freezing temperature), you will have to get a tank heater and place it on one side of the tank. 

This should get the temperature back to the ideal range within a few minutes, after which you can discontinue use. If you find that the temperature of your tank is significantly higher (hotter), you will need to purchase a tank chiller.
