Axolotls are fascinating amphibians that retain juvenile characteristics throughout their lives. Their welfare in captivity depends critically on water quality and appropriate temperature management.
Axolotls in captivity frequently suffer from inappropriate water temperature and inadequate filtration. Temperatures above 22 degrees Celsius cause heat stress, immune suppression and increased susceptibility to fungal infections. The commonly recommended aquarium of 60 liters is marginally adequate for a single adult and provides little margin for water quality fluctuations. Substrate impaction causes progressive intestinal obstruction and is extremely common. Fungal infections are a chronic problem in overcrowded or poorly filtered systems. Despite their regenerative abilities, axolotls kept in poor conditions live significantly shortened lives compared to their potential 10-15 year lifespan. The pet trade primarily relies on captive-bred animals but the nearly identical genetic background creates vulnerability to disease.
