Do Black Axolotls Make Good Pets?

A black axolotl can make an excellent tank addition to the right home. Of course, they don’t work well alongside other mates of different species, but they can live together peacefully in certain circumstances.

Black axolotls prefer to be alone, so there is no need to buy multiple. They are perfectly content with their own company.

Some axolotls can get aggressive towards tankmates, so supervision is necessary if you choose to house them together. Also, always make sure they are roughly the same size to avoid bullying or eating.

Even though axolotls are incredibly interesting-looking creatures, they are challenging to care for if you aren’t familiar with their unique needs. If you think you have what it takes without the experience, make sure you brush up on any necessary care facts.

The more you know, the better environment and care you can provide for these creatures.

Axolotls are instantly recognizable from their adorable looks. It looks like these creatures have permanently happy grins and unique color patterns. They have incredible spiky manes, adorable webbed feet, and eel-like bodies.

Black axolotls range from very dark to light gray. They have distinct spots along the top of their heads and backs.


How to Take Care of Black Axolotl

Black axolotls are aquatic freshwater amphibians. They require very specific water conditions to thrive. Once you have all the right components, your axolotl can live a full lifespan happily in their watery home.

Habitat, Tank Conditions & Setup


For one black axolotl, you need at least a 20-gallon tank. You should increase the size for every axolotl you have. They greatly benefit from having a lid, as they have been known to jump out of the water.

Since axolotls are purely aquatic, you don’t have to worry about any out-of-water spaces—so you may fill the tank completely.

Axolotls do not require filters, but they need to have a clean tank. Unsanitary living conditions can lead to several health issues. You can use a filter, as many hobbyists do. But always make sure it is the correct kind.

Sponge filters are among the most common types of products used in axolotl tanks because they collect debris without causing too much water movement.


Black axolotls need their tank to mimic the natural daytime/nighttime cycles in nature. As long as their water temperature stays within the 60 to 64-degree F range, they don’t need additional heating or cooling.

Water and pH

Your axolotl should have a water pH between 6.5-8.0.


Generally, for black axolotls, you can go the bare-bottom route. However, you may want to have tile or slate down to give them grip at the floor level.

You should never use small stones or particles like gravel. Axolotls are careless eaters and might ingest these pieces, leading to death if there is an intestinal blockage.

Keeping Your Black Axolotl Healthy

When you get an axolotl, you must locate an exotic vet or professional aquarist nearby. It’s best to have a knowledgeable professional on standby in case things go south.

Common Health Issues

If you keep your axolotl well-fed and in a clean environment, they’re unlikely to contract many illnesses.

However, they can still be susceptible to a few ailments, including:
  • Physical damage
  • Fungal infections
  • Bacterial infections
  • Parasites


Black axolotls have favorable life spans of up to 15 years. This is quite impressive, so you can plan on a lengthy friendship between the two of you.

Ultimately, the lifespan depends greatly on the overall diet, maintenance, and environmental perfection that you provide in captivity.


Black axolotls reach sexual maturity by 1 year of age. After that, females lay up to 200 eggs per clutch, landing on plants and other surfaces in the tank.

With a perfect temperature of 75 degrees F, babies should emerge within 15 days. At that point, you will need to separate the adults from the babies, as they may eat them.

Are Black Axolotls Friendly? Our Handling Advice

Black axolotls are interactive amphibians that might follow you through the tank. However, since they are purely aquatic, you should never handle them. They become highly stressed, even if you try to hold them in the water.

An axolotl out of water can die within just a few minutes. So, always make sure to resist the urge to touch unless it is a medical emergency.

Tank Behavior: What to Expect

Axolotls are solitary creatures that do best alone. They spend their days hiding behind, under, or inside any nook or cranny in their aquarium.

After some frequent interaction, your axolotl can recognize you. They have a vast amount of personality and may interact with you through the glass. They are curious and attentive creatures.

How Much Do Black Axolotls Cost?

Like many cold-blooded pets, black axolotls cost less as juveniles than they do as adults. But in total, you’re looking at prices between $20 and $70.
