Can Axolotls Eat Red Wigglers? What You Need to Know


Axolotls, also known as Mexican walking fishes, are unique amphibians that have become popular pets in recent years. Keeping axolotls as pets requires providing them with a proper diet that meets their nutritional needs. While axolotls are carnivorous and typically eat live or frozen foods, many axolotl owners wonder if they can feed their beloved pets with red wigglers, a type of earthworm commonly used as bait or in vermicomposting. In this article, we will explore whether axolotls can safely consume red wigglers and what considerations you should keep in mind.

The Nutritional Value of Red Wigglers

Red wigglers (scientifically known as Eisenia fetida) are highly nutritious worms that are commonly used in composting systems due to their ability to consume large amounts of organic waste. However, it is important to know that the nutritional composition of red wigglers may not be optimal for axolotls.

Potential Risks

While axolotls are capable of eating a variety of live foods, it is essential to ensure that the food you provide them with is safe and non-toxic. There are a few potential risks associated with feeding red wigglers to axolotls that you should be aware of:

  • Parasites: Red wigglers, like many other earthworm species, can carry parasites. These parasites may not be harmful to the worms themselves, but they could potentially harm your axolotl.
  • Chemical contamination: If the red wigglers you feed your axolotl come from a source that uses chemicals or pesticides, those substances could transfer to your pet, causing harm or even toxicity.
  • Allergies or adverse reactions: Some axolotls may have allergies or adverse reactions to certain foods. Red wigglers, as a different type of food than their natural prey, might cause digestive issues or other health problems in sensitive individuals.

Safe Alternatives

To ensure the well-being of your axolotl and mitigate potential risks, it is recommended to opt for safer alternatives as part of their diet. Here are some suitable food options:

  • Live or frozen fish: Axolotls predominantly thrive on a diet of fish. Feeder fish such as brine shrimp, bloodworms, or daphnia can provide the necessary nutrients and are generally safer options.
  • Commercial axolotl pellets: High-quality axolotl pellets specifically designed for their nutritional requirements are available in the market. These pellets usually contain a blend of essential nutrients and vitamins, providing a balanced diet for your pet.
  • Insects: Some axolotls may also enjoy small insects like blackworms, small crickets, or mealworms. These can be a good occasional addition to their diet.


While axolotls have a varied diet that can include live and frozen food, it is advisable to avoid feeding them red wigglers. The potential risks associated with parasites, chemical contamination, and adverse reactions make it safer to opt for alternative food sources. Always prioritize the well-being and health of your axolotl by providing a balanced and nutrient-rich diet to ensure their longevity and happiness as your aquatic companion.
