Can Axolotls Eat Red Wigglers? [You’ll Be Glad You Checked]

As a proud axolotl owner, you’re always on the lookout for the best dietary choices for your unique aquatic salamander.

Axolotls are fascinating creatures with specific dietary needs, and navigating through the myriad of food options available can sometimes be a bit confusing.

One food that might’ve caught your attention is the red wiggler.

But the pressing question remains: Can axolotls eat red wigglers?

Today, we’ll delve deep into the benefits, concerns, and expert opinions on feeding red wigglers to axolotls, ensuring that you have all the information you need to make an informed decision as to whether you proceed in doing so!

Can Axolotls Eat Red Wigglers?

Axolotls can eat red wigglers, both live and dead. These worms are high in protein and nutritionally balanced so are great to feed to axolotls of all ages. However, not all axolotls have a taste for them. It’s best to offer and observe if your axolotl takes a liking to them.

What Are Red Wigglers?

Red wigglers, scientifically known as Eisenia fetida, are a species of earthworm distinctively recognized by their reddish-brown color and agile movements. Naturally thriving in decaying organic matter, they are commonly found in rotting vegetation, compost, and manure piles.

One of the primary uses of red wigglers is in vermicomposting, a process where these worms transform organic waste into nutrient-rich compost, often referred to as worm castings.

This composting method is favored by many gardeners and eco-enthusiasts because red wigglers are exceptionally efficient at breaking down organic materials, enhancing soil quality in the process.

Benefits of Feeding Red Wigglers To Axolotls

Nutritional Benefits

Red wigglers are not only a natural food source but also pack a nutritional punch.

High in protein, they support the growth and muscle development of axolotls.

These worms also provide essential fatty acids, which play a significant role in maintaining the health of axolotls’ skin and internal organs.

The vitamins and minerals found in red wigglers, such as calcium, ensure that axolotls have strong bones and a robust immune system.

Engage Natural Feeding Behavior

Feeding axolotls with live red wigglers can stimulate their natural predatory instincts.

In the wild, axolotls are ambush predators, lurking and waiting for the right moment to catch their prey.

The movement of a live red wiggler triggers this instinct, allowing axolotls to exhibit their natural hunting behaviors.

This not only provides mental stimulation but also offers physical exercise, ensuring your axolotl remains active and engaged.

Where Can I Get Red Wigglers?

Red wigglers are widely available and can be found at most bait shops, garden centers, or online stores that specialize in composting supplies.

Their popularity in vermicomposting has made them a more accessible and affordable option compared to other exotic or specialized pet foods.

Moreover, for those who have a compost bin at home, a continuous supply of these worms is right at hand, making them a cost-effective feeding option.

Potential Concerns When Feeding Red Wigglers To Axolotls

When introducing any new food to your axies diet, it’s essential to be aware of potential risks and concerns.

While red wigglers offer several benefits for axolotls, there are a few considerations to keep in mind:

Toxins or Harmful Substances

Red wigglers are known to release a bitter-tasting substance when threatened, which might deter some predators.

This secretion is not toxic but can be distasteful to axolotls.

There’s a slight concern regarding where the worms are sourced from; if they come from areas with pesticides or harmful chemicals, they might ingest these toxins, which can then be transferred to the axolotl.

It’s crucial to source your red wigglers from reputable suppliers to ensure they are free from harmful substances.

Potential for Digestive Issues

Just as with any dietary change, there’s always a chance of digestive upset.

Some axolotls might have a sensitive stomach or may not adjust well to the introduction of red wigglers.

Overfeeding or offering worms that are too large might result in indigestion or even impaction.

Always monitor your axolotl after introducing a new food to ensure they’re digesting it without issues.

Wigglers Movements or Size

While the wriggling motion of red wigglers can stimulate the axolotl’s predatory instincts, there’s a small chance that an overly active worm might cause stress, especially for younger or more timid axolotls.

Additionally, the size of the worm matters. Feeding worms that are too large can be a choking hazard.

It’s always best to offer worms that are appropriately sized for your axolotl, ensuring they can be consumed easily.

How To Feed Red Wigglers To Your Axolotl

Incorporating red wigglers into your axolotl’s diet requires careful observation and a gradual introduction.

Here are some guidelines to help you with the process:

Introducing Red Wigglers

Start Small: Begin by offering a small number of red wigglers to gauge your axolotl’s interest. It’s not uncommon for axolotls to be hesitant or curious at first.

Monitor Reaction: Pay attention to any immediate reactions from your axolotl. If it shows disinterest or avoids the worm, you can try again at another feeding time. Some axolotls might require multiple exposures before accepting the new food.

Offer Differently: If your axolotl is wary of live red wigglers, you can try offering dead ones. The absence of movement might be less intimidating and can help in the transition.

Recommended Portion Sizes

Young Axolotls: For juveniles, offer small fragments of red wigglers initially, ensuring they’re manageable to consume.

Adult Axolotls: An adult axolotl can typically eat 2-3 full-sized red wigglers in one sitting, depending on the worm’s size and the axolotl’s appetite.

Frequency of Feeding

Young Axolotls: They have a higher metabolism and will require feeding once a day. You can mix red wigglers with other dietary items for variety and balanced nutrition.

Adult Axolotls: Mature axolotls can be fed red wigglers 3-4 times a week, interspersed with their regular diet. Always ensure that there’s no overfeeding; if you notice uneaten worms, reduce the quantity in the next feeding session.

Alternative Worms To Feed Your Axolotl

While red wigglers are a nutritious option for axolotls, they’re not the only worms that can be offered.

Different worm varieties come with their unique sets of advantages and challenges.

Let’s explore some alternatives to red wigglers, assessing their pros and cons in comparison.

Earthworms (Nightcrawlers)

  • Nutrition: Earthworms are protein-rich and an excellent source of nutrients for axolotls.
  • Pros: They’re large, making them suitable for adult axolotls. Easily found in bait shops or gardens, they’re often a favorite among axolotls due to their juicy texture.
  • Cons: They can be too big for juvenile axolotls, requiring them to be cut into smaller pieces. They also need to be sourced from clean, pesticide-free environments.

  • Cons: They can be pricier and are not as widely available as some other worm options.

Comparing Other Worms With Red Wigglers

Red wigglers are a middle-ground option. While they might not be as large as nightcrawlers, they’re bigger than bloodworms, making portion control easier.

The bitter secretion is a unique challenge not present in other worms. However, sourcing red wigglers can be easier due to their popularity in composting.

Nutritionally, they’re comparable to the other worms but always thrive when used in conjunction with other food sources for a varied diet.


Ultimately, feeding red wigglers to axolotls is generally safe and can be nutritionally beneficial.

However, like all dietary choices, it’s vital to follow best practices and follow the response and cues from your axie if you do decide to offer them.
