A brief overview of the Black Axolotl

Axolotls are highly fascinating underwater creatures that one can rear. They are called “Mexican walking fish” and are distinguished by their various colorings. While their wild counterparts are generally grey or dark green in hue, the albino variety of Axolotls is the most famous.

The black axolotl, also known as Ambystoma mexicanum, is a relatively new variation of the standard axolotl and has become extremely popular among hobbyists. These creatures are darker in color than their wild counterparts, adding a sense of mystery to an already intriguing animal.

This variation results from carefully choosing and breeding certain individuals, but their genetic predecessors originated solely from Lake Xochimilco in Mexico.

Despite common opinion, a black axolotl is not a fish or reptile but a salamander that can live in water and on land.

What sets them apart is their neotenous nature. This means that they remain in their larval stage as adults. Typically, an amphibian would undergo metamorphosis and leave its larval stage in the water when transitioning to land. However, black axolotls diverge from this pattern as they maintain their aquatic larval form throughout their lifetime.


Physical characteristics


The black axolotl is a unique amphibious salamander with distinctive physical characteristics. It has a long, tadpole-shaped tail with fleshy fins above and below. Its front legs have four slightly webbed toes, while its rear legs have five.

These creatures have six frilly appendages sprout from the back of their heads, creating a crown-like profile. These appendages are external gills that the axolotl uses to breathe underwater. Its body is black or slightly purple, while its eyes are black. Overall, the black axolotl is a fascinating and mysterious creature that intrigues any pet owner.

Differences between male and female Black Axolotl

To determine the gender of an axolotl, one can simply check for an enlarged cloaca, which is the genital area. While males and females have a cloaca, males have larger ones compared to females. This can be observed by looking behind the back legs and under the tail for a rounded bulge. If such a bulge is present, then the axolotl is a male.

Female axolotls have a more circular contour compared to males. This is because their physique is designed to hold eggs. It is possible to differentiate between male and female axolotls by observing their body shape.


Average lifespan of Black Axolotl

The average lifespan of a Black Axolotl can range from 10 to 15 years in captivity and about 5 to 10 years in the wild. However, various factors can influence their lifespan. Providing proper care, including a suitable habitat, appropriate feeding, and maintaining good water quality, can greatly impact their longevity.

Axolotls kept in substandard conditions or not fed a nutritious diet may be more susceptible to disease and have a shorter lifespan. Therefore, it is essential to prioritize their care and ensure that their needs are met to help them live a long and healthy life.

Factors affecting lifespan

Several factors can affect the lifespan of a Black Axolotl. Firstly, genetics plays a significant role. Some axolotls are predisposed to shorter or longer lifespans based on their genetic makeup.

Secondly, the quality of care provided is crucial. Axolotls kept in substandard living conditions or fed a poor diet are more likely to experience health issues and have shorter lifespans.

Environmental factors such as water temperature and water quality can also impact the lifespan of a Black Axolotl. It is vital to ensure that the axolotl’s habitat is well-maintained and provides optimal conditions for their health and longevity.

Growth rate and size expectations

There are a few things to remember regarding Black Axolotls’ growth rate and size expectations. These aquatic creatures have the potential to reach lengths of 11 to 12 inches, with their tails making up most of that measurement. It’s important to note that Black.

Axolotls can grow quite quickly, especially in the first few months of their lives. To help support their growth, providing them with a spacious tank that meets their needs is essential. You can expect your Black Axolotl to reach its full size and thrive with proper care and a suitable environment.

Recommended diet for Black Axolotl

The recommended diet for Black Axolotls consists of various live and dead foods. They are natural carnivores and need a high-protein diet to stay healthy. Some good options for food include live prey such as earthworms, bloodworms, and blackworms. They can also be fed bits of beef heart, raw fish, and frozen-thawed Mysis shrimp.

It’s essential to find the right mix of foods your Axolotl is interested in and stick to a feeding schedule to avoid overfeeding. Adults only need to eat once or twice a week, while juveniles require three meals weekly. By providing a balanced diet, you can ensure that your Black Axolotl stays healthy and happy.


Tank requirements

When it comes to tank requirements for black axolotls, size is key. These creatures need ample space to swim and explore, so experts recommend a tank with at least 20 gallons of water.

However, if you can go bigger, that’s even better! It’s essential to prioritize floor space over height to accommodate their size.

Regarding substrate, smooth sand is the preferred option to avoid ingestion issues. Additionally, adding plants and caves for hiding spots reduces stress. Remember to maintain stable water conditions and provide a low to moderate flow.

Water quality

Maintaining good water quality is essential for the health and well-being of your black axolotl. These unique amphibians are sensitive to environmental changes, and poor water conditions can lead to stress, illness, and even untimely death. It’s important to monitor and maintain the appropriate parameters, such as pH and temperature, to ensure a stable and suitable habitat for your axolotl.

Regular water changes, along with the use of a reliable filtration system, can help remove waste and maintain optimal water quality. By providing clean and well-maintained water, you can help your black axolotl thrive and enjoy a long and happy life.

Temperature and lighting

Temperature and lighting are important factors when caring for a black axolotl. These amphibians prefer a water temperature between 60 and 64 degrees Fahrenheit.

The black axolotl prefers a pH level that ranges from 6.5 to 8.0, which is near neutral. Regarding water hardness, a range of 7 to 14 GH is ideal.

Maintaining a stable temperature within this range is crucial to ensure your axolotl’s well-being.

As for lighting, black axolotls do not require bright or powerful lights. In fact, they prefer low levels of light. Many hobbyists use room lighting to create a natural day and night cycle for the axolotls. Avoid using strong lighting rigs that could cause stress to your axolotl.

Tank maintenance

Proper tank maintenance is crucial for the health and well-being of your Black Axolotl. Regular water changes are necessary to maintain water quality and prevent the buildup of harmful toxins. It is recommended to change about 20% of the water every week.

You should also clean the tank and remove uneaten food or waste to prevent ammonia spikes. Keeping the substrate clean and removing debris or dead plants is also essential.

Regularly checking and adjusting water parameters such as temperature and pH will help ensure a suitable environment for your Axolotl. Maintaining a clean and stable tank can provide the best care for your Black Axolotl.

Tank mates

Compatible fish species

When selecting tank mates for your Black Axolotl, it’s essential to consider their unique temperament and requirements. Black Axolotls are natural predators threatening smaller fish, snails, and shrimp.

Their delicate gills can also be easily injured during interactions with other species. However, some compatible fish species, such as White Cloud Minnows, can coexist peacefully with Black Axolotls.

These peaceful, calm water fish are a great option as they don’t have spines or shells that could harm the axolotl. Always ensure the tank is spacious enough to accommodate all the inhabitants comfortably and monitor their interactions closely to ensure the well-being of all the species.

Social behavior

These creatures are not particularly social and tend to prefer living alone. They can be aggressive towards other tank mates, including other axolotls, and may even nip at each other’s gills.

It is essential to provide them with plenty of hiding spaces and ensure they have enough room to roam comfortably in their tank. While they may not interact with each other much, black axolotls can form a bond with their owners and may even respond to them when approached. Their curious nature makes them a joy to raise and observe.



On the other hand, a pair that has formed a strong attachment can live together harmoniously and are capable of reproducing annually.

To begin the breeding process, prepare a distinct aquarium with artificial vegetation. The presence of these plants is essential as they serve as a protective environment for the eggs as the female uses them.

Feed them a diet rich in high levels of protein to prepare them. Some experts advise gradually reducing the temperature by five degrees from the usual tank temperature, which can encourage the male to start spawning.

Female organisms distribute around 200 eggs by spreading them onto various surfaces within the tank. Following the egg-laying process, gradually increase the temperature. Approximately 15 days later, the eggs will emerge from their shells.

Take out the mature axolotls and let the juveniles grow independently. Offer nourishing food with a lot of protein every three days to maintain the good health of the youthful black axolotls.

Health Concerns

Common health issues

While axolotls are generally hardy creatures, there are some common health issues that owners should be aware of. Poor water quality and chronic stress can lead to bacterial infections, skin lesions, and other health problems.
