What Makes Axolotls Unique?
The axolotl (Ambystoma mexicanum) is one of the most fascinating pets you can keep. These fully aquatic salamanders are known for their permanent smile, feathery gills, and remarkable ability to regenerate lost body parts.
Axolotls are neotenic, meaning they retain their larval features throughout their entire adult life. While most salamanders lose their gills and move onto land, axolotls keep their external gills and stay fully aquatic forever.
Basic Care Requirements
Tank
Minimum 75 liters (20 gallons) for one axolotl, plus 40 liters for each additional one.
Temperature
16-20°C (60-68°F), never above 23°C. A chiller may be needed in warm climates.
Water
Dechlorinated, stable pH between 6.5 and 8.0. Full water parameters guide.
Filter
Gentle filtration (sponge filter recommended). Strong currents stress axolotls.
Substrate
Fine sand or bare bottom. No gravel, which can be ingested and cause impaction.
Hides & Lighting
At least one hide per axolotl. Low to moderate lighting (no eyelids, prefer dim conditions).

Common Mistakes to Avoid
Using gravel substrate: axolotls swallow gravel while feeding, causing fatal impaction. Water too warm: temperatures above 23°C cause stress and infection risk. Overfeeding: adults need food only 2-3 times per week. Strong water flow: axolotls are poor swimmers. Skipping the nitrogen cycle: always cycle your tank for 4-6 weeks before adding an axolotl.
