Axolotl melanoid is a genetic mutation that eliminates iridophores, which produce reflecting colors in wild-type axolotl skin. As a result, melanoid axolotls have a uniformly dark coloration, often described as black, brown, or grey. This unique coloration makes them a sought-after addition to many axolotl enthusiasts’ collections.
Importance of Understanding Axolotl Melanoid
Understanding axolotl melanoid is vital for several reasons. First, it helps us better understand axolotls’ genetic diversity and how this can lead to unique physical characteristics.
Second, pet owners can use axolotl genetics to make breeding and genetic health decisions. It can also help people recognize their melanoid axolotls’ distinctive beauty and provide outstanding care.
What is Axolotl Melanoid?
Definition of Melanoid Mutation in Axolotls
Axolotl melanoid is a unique color variation resulting from a genetic mutation that affects the pigmentation of axolotls. This mutation affects the cells responsible for producing reflective pigments in the skin, resulting in a lack of iridophores and a uniformly dark coloration. While wild-type axolotls typically have a mottled appearance with lighter and darker patches, melanoid axolotls have a solid dark color.
Characteristics of Axolotl Melanoids
In addition to their unique coloration, melanoid axolotls have several distinguishing characteristics. These axolotls have thick and shiny skin, which gives them a sleek and glossy appearance. Their skin is also less translucent than wild-type axolotls, making it more difficult to see their internal organs. Iridophore-free skin gives melanoid axolotls a “starry” appearance and darker eyes.
Comparison to Wild-Type Axolotls
When compared to wild-type axolotls, melanoid axolotls have several notable differences. The most obvious is their coloration, which is uniform and dark rather than mottled. Wild-type axolotls tend to have more translucent skin, making it easier to see their internal organs. They also have lighter and darker patches on their skin, creating a mottled appearance.
Regarding behavior and care, melanoid axolotls are not vastly different from wild-type axolotls. They require similar tank conditions, diet, and maintenance. The main difference lies in their genetic makeup and unique coloration.

Genetics of Axolotl Melanoid
Inheritance of the Melanoid Gene
In axolotls, the melanoid gene follows a straightforward Mendelian pattern of inheritance. The offspring of a parent with the gene have a 50% chance of inheriting it. If both parents carry the gene, the chance of offspring inheriting it increases to 75%. The melanoid gene is recessive, meaning an axolotl must inherit two gene copies to express melanoid coloration.
Types of Melanoid Genes in Axolotls
There are several types of melanoid genes in axolotls, each resulting in a slightly different shade of dark coloration. These include:
- Black Melanoid: Produces a solid black coloration
- Brown Melanoid: Produces a dark brown coloration
- Copper Melanoid: Produces a reddish-brown coloration
- Olive Melanoid: Produces a greenish-brown coloration
Role of Genetics in Axolotl Melanoid Expression
Despite widespread knowledge of its heritability, how the melanoid gene behaves in axolotls remains the subject of investigation. The melanoid gene impacts skin reflective pigment formation, but the genes and processes are still in research. It is also unclear why some axolotls with two copies of the melanoid gene express the coloring more strongly.
Factors such as temperature and diet may also play a role in the expression of melanoid coloration in axolotls. Some breeders have reported that keeping axolotls in cooler water can enhance melanoid coloration. In contrast, others have found that feeding axolotls a diet high in carotenoids can result in a deeper coloration.

Keeping and Caring for Axolotl Melanoids
Tank Requirements for Axolotl Melanoids
Axolotls, including melanoidin, require a spacious, well-maintained tank with appropriate water conditions. A single axolotl needs 20 gallons, and every additional one needs 10. The tank should have a secure lid to prevent algae growth and the axolotl from jumping out.
Tank water should be 60-68°F (15-20°C) and pH 7.4-7.6. A mild filter can preserve water quality, while solid currents stress the axolotl.
Diet and Feeding Habits of Axolotl Melanoids
Axolotl melanoids are carnivorous and require a diet high in protein. Pellets, fresh or frozen bloodworms, brine shrimp, and even tiny bits of fish are all good feeds for them. It is essential to avoid overfeeding axolotls, as they are prone to obesity and can develop health problems as a result.
Feed axolotls small meals twice daily to avoid water quality issues and eliminate uneaten food. It is also essential to provide a variety of foods to ensure that the axolotl receives a balanced diet.
Special Considerations for Caring for Axolotl Melanoids
Axolotl melanoids require special considerations when it comes to their care. The dark coloration of melanoids can make detecting signs of illness or injury more complex, so regular health checks are recommended. It is also essential to provide hiding places in the tank, such as caves or plants, as axolotls can become stressed if they do not have a place to retreat to.
Axolotls are chemically sensitive. It would help if you were on top of treatments and medications. Axolotls can choke on gravel in the tank, so avoid using it.

Breeding Axolotl Melanoids
Breeding Strategies for Axolotl Melanoids
Axolotl melanoids breeding can be a rewarding and challenging experience for hobbyists and breeders alike. One of the most important aspects of breeding is choosing genetically healthy axolotls without known health problems. It is also essential to ensure that the axolotls are mature enough for breeding, as breeding too early can cause health problems for both the parent and offspring.
Several breeding strategies can work for axolotl melanoids, including natural, controlled, and line breeding. Natural breeding involves allowing the axolotls to mate independently in a suitable environment. In contrast, controlled breeding consists in selecting the breeding pair and managing the domain and timing of the mating. Line breeding involves breeding related axolotls to maintain specific traits or characteristics.
Inheritance Patterns of Melanoid Genes in Offspring
Axolotl melanoid genetics can be complex, with multiple genes and alleles involved in determining the expression of the melanoid trait. Melanoid traits are recessive, meaning both parents must carry the gene for the offspring to produce them.
25% of axolotls with one copy of the melanoid gene will have homozygous offspring that express the characteristic. 50% probability the offspring will be heterozygous for the melanoid gene and carry one copy, 25% chance they won’t.
Potential Challenges in Breeding Axolotl Melanoids
Breeding axolotl melanoids can present several challenges, including issues with health, genetics, and environmental factors. Inbreeding can lead to genetic problems, while outbreeding can dilute the melanoid trait or introduce undesirable characteristics. Breeding axolotls that carry other genetic mutations can also complicate the inheritance patterns of the melanoid gene.
Environmental factors such as temperature, water quality, and stress levels can also affect the success of breeding axolotl melanoids. Creating a reproductive setting that matches the axolotl’s natural habitat and monitoring the breeding pair is essential.
