Freshwater Axolotl
Unique marvels - Add some variety to your aquarist hobby with an Axolotl.
Walking fish, or axolotls, are actually not fish at all but a unique species of salamander. Most salamanders lose their iconic frill-like gills as adults - but axolotls keep them for life.
Axolotls retain their external gills throughout their lifetime, giving them their iconic feathery appearance. Selective breeding has led to an incredible range of colour forms, including albino, leucistic, wild type and melanoid. Axolotls can reach around 20 cm (9') and may live up to 20 years, though 10 years is more typical.
Axolotl Care
Axolotls aren't the lowest-maintenance aquatic pet, but caring for them is straightforward when you follow a few key rules. Despite their impressive regenerative abilities, they are not immune to bacterial infections - meaning clean water is essential. Colours vary between albino, leucistic (white with dark eyes), wild type (mottled dark grey) and melanoid (deep grey with minimal iridescence).
Axolotl Natural Habitat
Axolotls are naturally found only in Lake Xochimilco and previously Lake Chalco in Mexico City. Due to habitat loss and urban expansion, they are now critically endangered in the wild. Today, almost all axolotls exist only through responsible captive breeding programs.
Axolotl Behavior/Compatibility for Axolotl
Axolotls are calm, solitary-friendly animals that can be kept together as long as the tank is spacious. However, they are opportunistic carnivores and will attempt to eat anything that fits in their mouth. Their delicate external gills make them incompatible with almost all fish. Axolotls should not be kept with warm-water species, bottom-feeders, or fin-nipping fish. Avoid mixing juveniles with adults, and separate individuals that show aggression.
Axolotl Tank Set-up Tips
-
Tank
Axolotls grow large and produce significant waste, making tank size extremely important. A 136 litre (30 gallon) tank is ideal for one axolotl, with a larger tank required for multiple axolotls. Overcrowding increases stress and biting, so two axolotls per tank is ideal.

Base
Gravel is risky, as axolotls may swallow it. For safety, choose a sand substrate, large smooth stones, or no substrate at all to make waste cleanup easier.
-
Foliage
Axolotls often uproot delicate aquarium plants. Floating or hardy plants work best, such as Anubias. Secure plastic plants can also be used. Provide hiding spaces with driftwood, caves, and decorations.
-
Water
Axolotls require cool water between 16-20°C (60.8-68°F), and must never exceed 24°C (75°F). Keep their aquarium out of sunlight and consider insulation or a water cooler if your climate is warm.
Your pH should be 5.5-7.8 with 5-15 dGH hardness. Use a testing kit to monitor conditions. Filtration must be strong but gentle, as they dislike fast currents.
Regularly clean the substrate and treat tap water with appropriate water conditioners to remove chlorine and fluoride.
Feeding and Care
Axolotls are carnivores and thrive on live foods. Juveniles enjoy bloodworms, daphnia and brine shrimp, while adults thrive on earthworms and quality sinking pellets. Explore our fish food selection for suitable options.
