FAQ

What should I know about the salamander's species／breed and lifespan?

The axolotl is a distinctive salamander that keeps its aquatic larval form for life (neoteny) and has become extremely popular in Asian markets in recent years; the adult never metamorphoses and lives in water for its whole life (it does not come onto land as most salamanders do). The fire salamander and most salamanders／newts, by contrast, have a semi-aquatic life history (aquatic larvae, with adults spending most of their time on land). Lifespan is commonly understood to be [No single authoritative figure for this item: the whitelisted sources give no reference value for a specific lifespan year count for the axolotl／fire salamander]. The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should I know about the salamander's normal physiological indicators?

For fully aquatic species (such as the axolotl), the main items to monitor are body colour (whether too pale／too red), the appearance of the gills (whether the external gills are full and intact — atrophied or blackened gills are an abnormal warning sign), activity level and body condition; for terrestrial salamanders, skin moisture and integrity also need to be observed. Figures [No single authoritative figure for this item: the whitelisted sources give no reference value for a normal body colour／body condition range specific to salamanders; as with frogs, the literature on amphibian physiological reference values is itself thin, and this is not a matter of insufficient searching, verified 2026-07-30].

What should I know about the salamander's husbandry environment?

The axolotl must be kept in water for its whole life; keepers often mistakenly believe it will "grow up, metamorphose and come onto land" and so fail to maintain water quality properly — a major and common misunderstanding. Water temperature needs to be on the cool side (the axolotl is a temperate species and does not tolerate heat; overheating is a common cause of death. Peer-reviewed literature notes that the ideal water temperature for rearing in the laboratory is 16–18°C, that the species is native to Mexican lakes below 16°C, that above 24°C it becomes stressed, loses appetite and grows more susceptible to parasites, and that below 24°C growth can be accelerated without evident harm while above that the developmental rate declines — PMC: "ideal water temperatures for rearing axolotls in the lab is 16–18°C" "Water temperatures above 24°C can put stress on the animals and result in a loss of appetite...and may make axolotls more vulnerable to parasites" <https://pmc.ncbi.nlm.nih.gov/articles/PMC10000224/>, verified 2026-07-30.
