How Big Do Axolotls Get

Are you wondering just how big axolotls can get? These fascinating amphibians have captivated the hearts of pet owners and enthusiasts alike with their unique features, including their ability to regenerate body parts. But when it comes to their size and growth potential, there are many questions to be answered.

Whether you’re a beginner or an experienced axolotl owner, understanding these factors is crucial for providing proper care and ensuring your pet’s health and well-being. So, let’s dive in and explore everything you need to know about how big axolotls can grow!

How Big Do Axolotls Get?

Size is one of the most notable features of axolotls, and they can range in size from just a few inches to over a foot long. The average length for adult axolotls is around 9-10 inches, although some may grow up to 12 inches or more.

Axolotl growth rates can vary greatly depending on factors such as diet, water quality, and genetics. Juvenile axolotls can grow quite rapidly during their first year of life, increasing in size by several centimeters per month. However, once they reach adulthood at around 18 months old, their growth tends to slow down significantly.

It’s important to note that while some sources claim that female axolotls tend to be larger than males on average; this isn’t always the case. In fact, there are many instances where male axolotls have been observed growing larger than females.

Despite their relatively small size compared to other aquatic animals like fish or turtles; it’s essential not to underestimate the space requirements needed for an axolotl tank setup. Each individual should have at least ten gallons of water available with plenty of hiding spaces and plants for them to explore.

In summary, understanding how big your pet axolotl will ultimately get depends on several factors such as age and gender but overall feeding habits play an essential role in determining its final adult size!


The axolotl is a unique amphibian species that never undergoes metamorphosis, which means it retains its larval form throughout its life. One of the most fascinating aspects of this creature is its size.

Axolotls are relatively small creatures, with adult sizes ranging from 6 to 18 inches (15 to 45 cm) in length. Their size can vary depending on several factors such as genetics, diet, and environment.

One interesting fact about axolotls is that they have the ability to regenerate their limbs and even parts of their spinal cord if injured or damaged. This allows them to grow back any lost body parts over time without affecting their overall size.

When compared to other salamander species, axolotls are considered larger due to their lack of metamorphosis. However, in comparison to other aquatic animals such as fish or turtles, they may appear small.

While not particularly large by animal standards, the unique characteristics of the axolotl make it an intriguing subject for study and admiration.


Axolotls are fascinating creatures that have captured the attention and interest of many. One of the most intriguing aspects of axolotls is their growth process. The growth rate of an axolotl depends on various factors such as genetics, diet, temperature, water quality, and overall health.

Axolotls start out as tiny larvae around 1 inch long when they hatch from their eggs. As they age and develop, their bodies undergo significant changes in size and structure. They grow rapidly during the first year or two of life but slow down considerably after reaching maturity.

During this time period, it’s essential to monitor your pet axolotl’s growth regularly to ensure that they’re receiving adequate nutrition and care. A healthy axolotl can reach up to a foot in length while some larger specimens can grow up to 18 inches!

It’s important to note that if an axolotl isn’t growing at a steady pace or seems smaller than average for its age group, there may be underlying health issues that need addressing. By providing proper care including feeding high-quality food items like pellets or live foods rich in nutrients with regular water changes you can help your pet achieve optimal growth rates!


Axolotls are known for their unique physical appearance and gentle temperament, but have you ever wondered about their weight? Well, axolotls can weigh anywhere from 50 grams to over 500 grams. The average weight of an adult axolotl is around 200-250 grams.

The weight of the axolotl varies according to its size and age. Younger axolotls will typically weigh less than adults as they are still growing and developing. As they reach sexual maturity, they tend to gain more weight.

Weight can also be influenced by factors such as diet and environmental conditions. Axolotls that are fed a balanced diet with plenty of protein will tend to grow larger and heavier compared to those who do not receive adequate nutrition.

It’s important to note that excessive weight gain in axolotls can lead to health problems such as obesity, which increases their risk of developing diseases like fatty liver disease or gout.

Therefore it is crucial for owners should monitor the growth rate of their pet’s body mass index (BMI) regularly. By monitoring your pet’s BMI, you’ll be able to spot any abnormal changes in its overall health quickly.

Understanding an Axoltols’ ideal weight range is necessary for maintaining healthy pets.


Axolotls are carnivores and their diet primarily consists of live or frozen foods. The most common food for axolotls is earthworms, which are high in protein and easy to digest. They also enjoy brine shrimp, bloodworms, small fish such as guppies or minnows, and even pellets specifically formulated for axolotls.

It’s important to note that feeding your axolotl a varied diet is essential for their health. Providing them with the same type of food every day can lead to nutrient deficiencies and other health issues. It’s recommended that you feed your axolotl 2-3 times a week but don’t overfeed them as it can cause obesity.

One thing to keep in mind when feeding your axolotl is not to use any sharp objects like tweezers or forceps while feeding since they might accidentally hurt themselves with these tools during meal time.

Additionally, make sure you remove any uneaten food from their tank within an hour after feeding as leftover food can decay quickly leading to poor water quality which could affect the overall health of your pet.

Providing a balanced diet with different types of live or frozen foods would ensure healthy growth and development for Axolotle species.

Sexual maturity

Axolotls typically reach sexual maturity between 12-18 months of age. At this point, they will begin to display sexually dimorphic characteristics, such as differences in body size and shape.

Male axolotls have longer tails and slimmer bodies than females, while females tend to be wider-bodied with shorter tails. They also have a vent near their tail base which is used for laying eggs.

To determine if an axolotl has reached sexual maturity, you can observe the cloaca area of the animal – if it appears swollen or enlarged, this may indicate that the axolotl is ready to mate.

It’s important to note that just because an axolotl has reached sexual maturity does not mean they should be bred immediately. Breeding should only occur when both male and female are healthy enough for reproduction and proper care can be provided for any resulting offspring.

Understanding the signs of sexual maturity in your axolotl can help ensure their overall health and well-being as they enter adulthood.

Life span

Axolotls have a relatively long lifespan for an aquatic salamander. On average, they can live up to 10-15 years if kept in proper conditions. However, some axolotls that are well taken care of can even surpass this age and live up to 20 years or more.

The life span of an axolotl is largely dependent on its living environment and how well it is being cared for. Axolotls require clean water with appropriate temperature and pH levels, as well as a balanced diet consisting of live or frozen foods such as bloodworms, brine shrimp, and pellets.

It’s important to note that factors such as genetics, illness/disease, and stress can also affect the life span of an axolotl. Therefore, regular monitoring of their health by observing their behavior and physical appearance is crucial in ensuring they live a long healthy life.

With proper care and attention given to them throughout their lives – from infancy through adulthood – axolotls have the potential to reach impressive ages!

In captivity

When it comes to keeping axolotls in captivity, there are a few things you need to keep in mind. Axolotls require specific water conditions and adequate space to thrive. A single adult axolotl should be kept in at least a 20-gallon tank with plenty of hiding places.

It’s important to maintain the water temperature between 60-68°F as anything outside this range can have negative effects on their health. Make sure that the pH level is around 7.4-7.6, and always use dechlorinated water when filling up your tank.

Axolotls are carnivores, which means they require a protein-rich diet consisting of live or frozen food such as bloodworms or brine shrimp. Feed them once every day or every two days but avoid overfeeding as it can lead to obesity and other health issues.

Keep an eye on your axolotl’s behavior regularly to ensure they’re healthy and happy in their environment. Ensure that their surroundings stay clean by performing regular water changes weekly ranging from 10% -25%.

By following these guidelines for captive care, you’ll help ensure your axolotl lives out its full lifespan under ideal conditions!


Axolotls are fascinating creatures that have captivated the hearts of many pet owners. They come in various colors and sizes and can be a great addition to any aquarium or home.

As we’ve learned, axolotls can grow up to 12-14 inches long but tend to vary in size based on gender, genetics, diet, and environment. Their growth rate is also determined by these factors.

Their diet plays a crucial role in their development; feeding them a balanced diet with plenty of protein will help them reach their full potential. Sexual maturity occurs at around one year old for males and 18 months for females. In captivity, they can live up to 10-15 years.

Caring for an axolotl requires some knowledge about their behavior and needs. With proper care and attention, you’ll enjoy watching your axolotl grow from a tiny tadpole into a beautiful amphibian that brings joy into your life!
