Feeding Axolotls: Can They Eat Goldfish?


Axolotls, unique and captivating aquatic creatures, are popular pets among amphibian enthusiasts. The question often arises: Can axolotls eat goldfish? In this article, we will explore the dietary requirements of axolotls and determine whether goldfish are a suitable option for their meals.

The Natural Diet of Axolotls

Axolotls are native to the lake complex of Xochimilco near Mexico City. In the wild, they primarily feed on small aquatic organisms, including crustaceans, worms, insects, and small fish. Their diet is rich in protein and low in fat.

Understanding Axolotl Nutrition

Axolotls are carnivores, meaning their diet mainly consists of animal matter. Protein is essential for their growth, development, and overall health. It is important to ensure that their diet provides adequate protein while avoiding excessive fat.

Can Axolotls Eat Goldfish?

While goldfish are frequently available and may seem like a convenient option, they are not the ideal food source for axolotls. Goldfish are high in fat content, which can lead to health issues in axolotls, including obesity and liver disease. Additionally, goldfish are not as nutritionally beneficial as other alternatives that closely resemble axolotls’ natural diet.

Alternative Food Choices for Axolotls

To achieve a healthy and balanced diet for your axolotls, it is best to offer a variety of suitable alternatives. Here are some options:

1. Earthworms

Axolotls have a strong preference for earthworms. They are an excellent source of protein and stimulate natural foraging behavior. Be sure to use pesticide-free earthworms or purchase them from a reliable source.

2. Insects

Feeder insects such as black soldier fly larvae, crickets, and small mealworms can be included in the axolotls’ diet. However, it is crucial to ensure that these insects are appropriately sized to avoid any potential choking hazards.

3. Pellets and Commercial Foods

There are commercially available axolotl pellets and food options specifically formulated to meet their nutritional requirements. These can be used as supplementary feeding alongside live foods. Always choose high-quality pellets made from natural ingredients.

4. Small Fish

As axolotls naturally consume small fish in the wild, suitable alternatives include small live or frozen fish such as bloodworms and daphnia. These should be used in moderation and not as a primary food source.

Feeding Tips for Axolotls

When feeding axolotls, it is essential to follow these guidelines:

  • Offer food that is appropriately sized, usually no larger than the width of the axolotl’s head.
  • Feed in small quantities to prevent overfeeding and water quality issues.
  • Remove any uneaten food after feeding to maintain water cleanliness.
  • Vary the diet to provide a balanced nutritional intake.


While goldfish may seem like a tempting meal option for axolotls, they are not the best choice due to their high-fat content. Opt for nourishing alternatives such as earthworms, insects, pellets, and small fish that resemble their natural diet. By providing a balanced and suitable diet, you can ensure the health and well-being of your axolotls.
