Appearance

The melanoid axolotl is one of the most striking morphs available. Its solid dark coloration ranges from deep gray to jet black, creating a dramatic appearance that stands out in any aquarium.

The key visual difference from wild type axolotls is the complete absence of shiny gold or silver speckling. Where a wild type sparkles, a melanoid is uniformly dark and matte.

Genetics

The melanoid trait is controlled by the "m" gene. It is autosomal recessive, meaning both parents must carry the gene to produce melanoid offspring.

Breeding two melanoids produces 100% melanoid babies. A melanoid bred with a non-carrier produces 0% melanoid offspring (but all carry the gene).

Melanoid can combine with other genes. A melanoid albino (melanoid + albino genes) creates an interesting dark-eyed white axolotl. A melanoid copper produces a very dark brownish animal.

Health Observation Tip

The dark coloration can make it slightly harder to spot health issues like redness or fungal patches compared to lighter morphs. Regular close observation during feeding time helps catch any problems early.

GFP Melanoid Is Spectacular

GFP melanoid axolotls are particularly popular because the green fluorescence contrasting against the dark body creates a spectacular visual effect under UV light. The dark background makes the glow far more dramatic than on lighter morphs.

Frequently Asked Questions

Frequently Asked Questions

What makes melanoid axolotls black?
Melanoid axolotls have an increased number of melanophores (dark pigment cells) and completely lack iridophores (shiny reflective cells). This gives them a solid dark appearance without any sparkle or shine.
Are melanoid axolotls rare?
No, melanoid axolotls are fairly common in the pet trade and typically cost $35-70. They are one of the standard morphs available from most breeders.
