Axolotl Breeding: Top 10 Tips!

Understanding Axolotls

What are Axolotls?

Axolotls are unique amphibians native to the lakes of Xochimilco in Mexico. Unlike other amphibians, they remain in their larval stage throughout their lives, a condition known as neoteny.

This means they retain their gills and aquatic lifestyle, making them distinctive and intriguing pets.

Natural Habitat and Behavior

In the wild, axolotls inhabit freshwater lakes and canals with plenty of vegetation and hiding spots.

They are nocturnal predators, feeding on small fish, worms, and insects.

Understanding their natural environment helps in recreating suitable conditions for breeding in captivity.

Preparing for Breeding

Setting Up the Right Environment

Before you start breeding axolotls, it’s essential to set up an environment that mimics their natural habitat.

This includes a spacious tank with plenty of plants, hiding spots, and clean, filtered water.

Ideal Tank Conditions

The tank should be at least 20 gallons for a pair of axolotls. Maintain a water temperature between 60-64°F (16-18°C), as axolotls thrive in cooler water.

Ensure the pH level is neutral, around 7.0, and use a gentle filtration system to avoid disturbing the axolotls.

Selecting Healthy Breeding Pairs

Choosing the Right Axolotls

Select axolotls that are at least 18 months old and have reached sexual maturity.

Look for healthy individuals with no signs of illness or deformities. It’s also important to consider genetic diversity to avoid inbreeding.

Health Checks and Genetic Considerations

Regular health checks are crucial. Ensure your axolotls are free from infections, parasites, and other health issues.

Genetic considerations are also important to maintain a healthy population and prevent genetic defects.

Creating the Perfect Breeding Environment

Temperature Control

Axolotls require stable temperatures for breeding. Use a reliable aquarium heater to maintain the temperature within the ideal range.

Sudden temperature fluctuations can stress the axolotls and hinder breeding.

Lighting and Water Quality

Axolotls prefer low lighting. Use dim lights or natural light to create a comfortable environment.

Additionally, ensure excellent water quality by performing regular water changes and monitoring ammonia, nitrite, and nitrate levels.

Feeding and Nutrition

Diet for Breeding Axolotls

Diet for Breeding Axolotls

A nutritious diet is essential for breeding axolotls. Provide a variety of foods such as earthworms, bloodworms, and high-quality pellets.

A well-fed axolotl is more likely to be healthy and fertile.

Supplements and Feeding Frequency

Consider adding calcium and vitamin supplements to their diet to boost their health.

Feed adult axolotls two to three times a week, ensuring they receive adequate nutrition without overfeeding.

Breeding Process

Signs of Readiness in Axolotls

Male axolotls develop swollen cloacal regions and may display more active behavior when ready to breed.

Females become rounder as they produce eggs. Observing these signs helps in determining the right time for breeding.

Mating Rituals and Behavior

Axolotls engage in a fascinating mating dance, where the male deposits spermatophores, which the female then picks up.

This process can take several hours, and it’s important to provide a stress-free environment during this time.

Egg Laying and Care

Identifying Fertilized Eggs

After mating, the female lays eggs on plants or other surfaces in the tank. Fertilized eggs appear translucent with a visible embryo inside.

It’s essential to separate the eggs from the parents to prevent them from being eaten.

Proper Care for Eggs

Place the eggs in a separate tank with similar water conditions. Keep the water clean and gently aerated.

It takes about two weeks for the eggs to hatch, during which they should be monitored closely.

Hatching and Larvae Care

Stages of Development

Axolotl larvae go through several developmental stages before becoming juveniles.

Initially, they are tiny and fragile, requiring careful handling and observation.

Feeding Larvae and Maintaining Water Quality

Feed the larvae with infusoria or baby brine shrimp initially, gradually moving to larger foods as they grow.

Maintain pristine water quality by performing frequent water changes and using a sponge filter to avoid sucking up the larvae.

Monitoring Growth and Development

Tracking Progress

Keep a journal to track the growth and development of the axolotls. Note any changes in behavior, size, and coloration.

This helps in identifying any issues early and ensuring they develop healthily.

Addressing Common Health Issues

Be vigilant for signs of common health problems like fungal infections or gill abnormalities.

Early detection and treatment are crucial to prevent the spread of diseases and ensure the well-being of the axolotls.

Genetic Diversity and Ethical Considerations

Avoiding Inbreeding

To maintain a healthy axolotl population, it’s important to avoid inbreeding.

Use unrelated breeding pairs and keep detailed records of your axolotls’ lineage to prevent genetic problems.

Ethical Breeding Practices

Ethical breeding involves ensuring the welfare of your axolotls and not breeding for traits that could harm their health.

It’s also important to educate potential buyers about responsible pet ownership.

Selling or Rehoming Axolotls

Finding Responsible Buyers

When it’s time to sell or rehome your axolotls, look for responsible buyers who are knowledgeable about their care requirements.

Online forums, local pet stores, and aquarium clubs can be good places to find interested individuals.

Tips for Rehoming

Provide detailed care instructions and ensure the new owners have the right setup before transferring the axolotls.

Follow up with them to offer support and advice as they adjust to their new pets.

Common Breeding Challenges

Troubleshooting Issues

Breeding axolotls can come with challenges, such as eggs not hatching or larvae not thriving.

Troubleshoot by checking water quality, diet, and environmental conditions, and seek advice from experienced breeders if needed.

Preventative Measures

Prevent issues by maintaining a clean environment, providing a nutritious diet, and monitoring the health of your axolotls regularly.

Preventative care is always better than reactive treatment.

Legal and Environmental Responsibilities

Understanding Regulations

Familiarize yourself with local regulations regarding the breeding and sale of axolotls.

Some areas have specific laws to protect native species and ecosystems.

Environmental Impact

Be mindful of the environmental impact of keeping and breeding axolotls.

Never release captive axolotls into the wild, as they can disrupt local ecosystems and spread diseases.


Breeding axolotls can be a fulfilling and educational experience when done responsibly.

By following these top 10 tips, you’ll be well on your way to successfully breeding healthy, happy axolotls.

Remember, responsible breeding not only benefits your pets but also contributes to the conservation of this unique species.
