Tank Requirements
20+ gallons for adult axolotl (8-12 inches). Fine sand only — never gravel.
Cold water (60-68°F). Most homes need a chiller in summer.
Diet
Earthworms (best), bloodworms (frozen), pellets specifically for axolotls.
Avoid live feeder fish — parasite risk and unnecessary stress.
Critical Substrate Note
Axolotls swallow gravel, causing fatal impactions. Use ONLY fine sand or bare bottom.
Bare bottom works fine — easy to clean, no impaction risk.
Common Health Issues
Heat stress (temperature above 70°F).
Skin fungal infections from poor water quality.
Limb regeneration is real — axolotls regrow limbs and even portions of organs.
- ✦Tap water dechlorinator essential — chloramine harms gills
- ✦Solo tanks recommended — axolotls bite each other's gills and limbs
- ✦Slow water flow — strong currents stress axolotls
