Axolotl (Ambystoma mexicanum)

The Axolotl (Ambystoma mexicanum), also known as the Mexican Walking Fish, is a fascinating neotenic salamander prized for its unique appearance and engaging behavior. Native to the ancient lakes of Mexico, this fully aquatic species remains in its larval form throughout its life, showcasing feathery external gills, a broad head, and a range of color morphs from wild type to leucistic and albino.

Basic Care Guide:

• Tank Size: Minimum 75–100 litres per adult axolotl

• Water Parameters: Cool freshwater (14–18°C), pH 6.5–8.0, with stable water quality maintained by efficient filtration

• Diet: Carnivorous—feeds on high-quality pellets, earthworms, bloodworms, and other protein-rich foods

• Tank Setup: Bare-bottom or fine sand substrate (avoid gravel to prevent impaction), with hiding spaces and low flow filtration

• Lighting: Low to moderate; axolotls prefer subdued light levels

• Compatibility: Best housed singly or with other axolotls of similar size to avoid stress or injury

Axolotls are a captivating choice for experienced aquarists seeking a unique and rewarding aquatic pet. Proper habitat, water quality management, and a consistent feeding schedule are essential for maintaining their health and longevity.
