This guide is written as an operating framework. Exact limits still depend on the organism, system volume, equipment and local rules.
Treat an axolotl as an amphibian
It has different skin, feeding, temperature and veterinary needs from aquarium fish.
Control heat
Warm water raises stress and disease risk. Plan room temperature, cooling and power-failure response before summer.
Use safe substrate
Avoid gravel that can be swallowed. Bare bottom, fine sand for suitable adults or secure large slate are common controlled options.
Keep flow gentle
Filtration must process waste without blasting the animal. Diffuse returns and observe gill posture and behaviour.
Feed complete appropriate foods
Earthworms and suitable complete carnivore foods are more dependable than relying on feeder fish.
Plan veterinary access
Amphibian illness can progress while signs remain subtle. Locate an experienced exotic or aquatic veterinarian before an emergency.
