Melanoid.  Melanoid axolotls have an elegant black pigmentation that especially contrasts well when housed with lighter-colored axolotls such as Golden Albino, Albino, and Leucistic axolotls.

The Melanoid axolotl is a striking color morph of the axolotl, distinguished by its completely dark, almost black appearance. Unlike other axolotl variants that may have pigmentation patterns, the Melanoid’s coloration is uniform, including the gills, skin, and eyes, giving it a sleek and dramatic look.

Physical Traits

• Color: Deep, dark brown to black; lacks the golden or iridescent shimmer seen in wild types.

• Eyes: Typically dark, blending seamlessly with the body.

• Gills: Dark-colored, often black or deep brown, enhancing its overall uniformity.

• Size: Comparable to other axolotls; adults typically grow 9–12 inches (23–30 cm) in length.

Behavior and Temperament

• Docile and calm: Like other axolotls, Melanoids are slow-moving and enjoy hiding in aquatic plants or caves.

• Nocturnal tendencies: They may be more active during low-light periods.

• Feeding: Carnivorous; enjoys worms, small fish, and specialized axolotl pellets.

Care Requirements

• Tank: Minimum 20 gallons for one adult; prefer clean, cool water (~16–18°C / 60–64°F).

• Water quality: Sensitive to poor water conditions; regular water changes are crucial.

• Substrate: Fine sand or bare-bottom recommended to prevent ingestion of gravel.

• Tank mates: Best kept alone or with other Melanoids; avoid smaller fish that could be eaten.

Genetics

The Melanoid morph is the result of specific genetic traits that reduce reflective pigment cells (iridophores) and yellow pigment (xanthophores), leaving only black pigment (melanophores). This makes them one of the most uniform and visually striking morphs available.

Popularity

• Highly sought after by axolotl enthusiasts for their unique, dramatic appearance.

• Often paired with other morphs for breeding to explore new color combinations.
