How Big Do Axolotls Get?

February 14, 2024

When fully mature, axolotls can grow up to ten inches long. They typically reach this size in around six months from birth.

They are very active and curious creatures that appreciate plenty of space in their tanks. They are sensitive to environmental changes such as temperature and nitrates which can be reduced by having a larger volume of water in their aquarium.

A minimum of a standard 20 gallon tank is recommended, but larger is preferred. It takes more time for axolotls to decompose their waste, and this process is less stressful on them with a larger volume of water in their habitat.

As far as food is concerned, axolotls are carnivorous and require a steady supply of protein to maintain their health. They love to eat a variety of fish-based foods such as bloodworms, beef heart and frozen brine shrimp. They also enjoy live worms such as red wigglers, mysis shrimp and nightcrawlers.

As with any pet, it is important to acquire an axolotl from a reputable breeder or rescue group. Make sure the seller can provide thorough documentation on their animal’s health and breeding history. A local exotic veterinarian is another great resource for finding a responsible breeder or rescue for your new axolotl.
