Will Axolotls Eat Fish? The Importance of Keeping Axolotls Alone


Axolotls, also known as Mexican walking fish, are fascinating creatures that have gained popularity as pets due to their unique appearance and docile nature. However, many new axolotl owners wonder if they can keep other fish in the same tank as their axolotl. The answer to this question is critical for the well-being of your axolotl and its potential tank mates. While axolotls can be kept with other aquatic animals, it is strongly recommended to keep them alone. Let's explore why.

Axolotls are Carnivorous

Axolotls are carnivorous creatures with a diet consisting mainly of worms, small insects, and small fish in the wild. In captivity, they are often fed a diet of bloodworms, brine shrimp, and specially formulated axolotl pellets. Due to their carnivorous nature, axolotls may view small fish as food rather than tank mates.

Even if the fish is too large for the axolotl to eat, the axolotl may still attempt to bite or nip at the fish, causing stress and potential injury.

Fish May Harm Axolotls

Fish, especially tropical fish, may carry diseases or parasites that can be harmful to axolotls. Additionally, some fish species are known to nip at the gills or fins of other fish, which can cause significant stress and injury to your axolotl. Therefore, it is best to keep axolotls alone to prevent potential harm.

Optimal Water Conditions Differ

Axolotls prefer cooler water temperatures between 60-70°F (15-20°C), while most tropical fish require warmer temperatures. Maintaining a temperature suitable for both axolotls and fish can be challenging and may lead to stress and illness for either one.


While it may be tempting to add fish to your axolotl tank, it is strongly recommended to keep axolotls alone. Axolotls are carnivorous and may view fish as food, while fish may carry diseases or parasites harmful to axolotls. Additionally, the optimal water conditions for axolotls and fish differ significantly. To ensure the health and well-being of your axolotl, it is best to keep them alone in a tank that caters to their specific needs.
