A Golden Gem of the Aquatic World
The Hypomelanistic Axolotl is a truly mesmerizing aquatic pet that captivates hobbyists with its glowing golden-yellow body and deep red, feathery gills. A rare morph of the beloved Ambystoma mexicanum, this axolotl offers the perfect blend of visual appeal, scientific intrigue, and low-maintenance care. Ideal for beginner and experienced aquarists alike, it’s a standout addition to any cool-water aquarium.
What Makes the Hypomelanistic Axolotl Unique?
This color morph retains partial melanin, giving it a soft, sun-kissed glow that sets it apart from albino varieties. Its external gills are striking—bushy, deep red, and highly functional, used for breathing in the water. Axolotls remain in their juvenile, aquatic state for life (a condition called neoteny), which gives them their charming, wide-headed, finned-tailed appearance.

Feeding
Axolotls are carnivores and thrive on a diet rich in animal protein. They feed by suction, snapping up food with quick movements of their wide mouths.

Regional Considerations for U.S. Keepers
Many regions in the U.S. have warmer ambient temperatures that can push your tank above the safe range for axolotls. In warmer months or southern climates, consider using a chiller or fan-driven evaporation to keep temps below 70°F.
Also, if your tap water is hard, use dechlorinated or partially RO-treated water to soften without losing mineral content.
