Axolotls, the enigmatic aquatic creatures native to Mexico, have captivated the hearts of many with their unique appearance and fascinating biology. Often referred to as “Mexican walking fish,” these amphibians are actually neotenic salamanders, meaning they retain their larval features throughout their lives. One of the most common questions among axolotl enthusiasts is, “What to feed an axolotl?” This question, while seemingly straightforward, opens the door to a broader discussion about their dietary needs, feeding habits, and even the peculiar connection between their diet and moonlight.

Understanding the Axolotl’s Natural Diet

To comprehend what to feed an axolotl, it’s essential to first understand their natural diet in the wild. Axolotls are carnivorous predators, primarily feeding on small aquatic creatures such as worms, insects, small fish, and crustaceans. Their diet is rich in protein, which is crucial for their growth, development, and overall health. In captivity, replicating this natural diet is key to ensuring their well-being.

Live Food Options

Bloodworms: Bloodworms are a popular choice for axolotl owners. These small, red larvae of the midge fly are rich in protein and are readily accepted by axolotls. They can be fed live or frozen, though live bloodworms are often preferred as they stimulate the axolotl’s natural hunting instincts.
Earthworms: Earthworms are another excellent source of nutrition for axolotls. They are high in protein and other essential nutrients, making them a staple in many axolotl diets. It’s important to ensure that the earthworms are free from pesticides and other harmful chemicals.
Brine Shrimp: Brine shrimp, particularly newly hatched ones (known as nauplii), are a great option for juvenile axolotls. They are small enough for young axolotls to consume and provide a good source of protein and fats.
Daphnia: Daphnia, also known as water fleas, are small crustaceans that can be fed to axolotls. They are a good source of protein and can help improve water quality by consuming algae and detritus.

Frozen and Pelleted Food Options

Frozen Bloodworms and Brine Shrimp: For those who prefer not to deal with live food, frozen bloodworms and brine shrimp are convenient alternatives. They retain much of their nutritional value and can be easily stored in the freezer.
Axolotl Pellets: Specially formulated axolotl pellets are available in the market and are designed to provide a balanced diet. These pellets typically contain a mix of proteins, vitamins, and minerals essential for axolotl health. It’s important to choose high-quality pellets and to avoid overfeeding, as uneaten pellets can degrade water quality.

Occasional Treats

Small Fish: Small fish, such as guppies or minnows, can be offered as occasional treats. However, it’s crucial to ensure that the fish are free from diseases and parasites that could harm the axolotl.
Crickets and Other Insects: Crickets and other small insects can be offered as treats, but they should be gut-loaded (fed a nutritious diet) before being given to the axolotl. It’s also important to remove any hard exoskeletons that could be difficult for the axolotl to digest.

Feeding Frequency and Portion Control

Understanding how often and how much to feed an axolotl is just as important as knowing what to feed them. Juvenile axolotls have higher metabolic rates and should be fed daily, while adult axolotls can be fed every 2-3 days. Overfeeding can lead to obesity and water quality issues, so it’s essential to monitor the axolotl’s weight and adjust feeding portions accordingly.

Signs of Overfeeding

Bloating: An axolotl that appears bloated or has a distended belly may be overfed.
Lethargy: Overfed axolotls may become lethargic and less active.
Water Quality Issues: Excess food can decompose in the tank, leading to ammonia spikes and poor water quality.

Signs of Underfeeding

Weight Loss: An underfed axolotl may appear thin or have a noticeable loss of body mass.
Reduced Activity: Underfed axolotls may become less active and spend more time hiding.
Poor Growth: Juvenile axolotls that are underfed may exhibit stunted growth.

The Curious Connection to Moonlight

While the primary focus of this article is on what to feed an axolotl, it’s worth exploring the curious connection between their diet and moonlight. In the wild, axolotls are known to be more active during the night, and their feeding behavior is influenced by the lunar cycle. Some studies suggest that axolotls may consume more food during the full moon, possibly due to increased activity levels and the availability of prey. This fascinating link between their diet and lunar phases highlights the intricate relationship between axolotls and their natural environment.

Moonlight and Feeding Behavior

Increased Activity: During the full moon, axolotls may exhibit increased activity levels, leading to more frequent hunting and feeding.
Prey Availability: The brightness of the full moon may make it easier for axolotls to locate and capture prey, resulting in a higher intake of food.
Circadian Rhythms: Axolotls, like many other animals, have circadian rhythms that are influenced by light. The lunar cycle may play a role in regulating their feeding patterns.

Implications for Captive Axolotls

While the connection between moonlight and feeding behavior is more pronounced in wild axolotls, it’s still an interesting consideration for those keeping axolotls in captivity. Providing a natural light cycle that mimics the lunar phases may help promote more natural feeding behaviors and overall well-being.

Conclusion

Feeding an axolotl involves more than just providing food; it requires an understanding of their natural diet, feeding habits, and the factors that influence their behavior. By offering a variety of live, frozen, and pelleted foods, monitoring feeding frequency and portion sizes, and considering the intriguing connection to moonlight, axolotl owners can ensure their pets thrive in captivity. As with any pet, it’s essential to stay informed and attentive to the unique needs of these fascinating creatures.

Q: Can axolotls eat vegetables? A: No, axolotls are strictly carnivorous and do not have the digestive system to process plant matter. Feeding them vegetables can lead to digestive issues and malnutrition.

Q: How do I know if my axolotl is getting enough food? A: A well-fed axolotl should have a plump, rounded body without visible ribs or spine. Regular monitoring of their weight and activity levels can help ensure they are receiving adequate nutrition.

Q: Can I feed my axolotl feeder fish from the pet store? A: Feeder fish can be offered as occasional treats, but it’s important to ensure they are free from diseases and parasites. Quarantining feeder fish before feeding them to your axolotl is recommended.

Q: How often should I clean my axolotl’s tank? A: Regular tank maintenance is crucial for axolotl health. Partial water changes should be done weekly, and the tank should be thoroughly cleaned every 2-4 weeks, depending on the size of the tank and the number of axolotls.

Q: Can axolotls eat human food? A: No, human food is not suitable for axolotls. Their diet should consist of high-protein, aquatic-based foods that mimic their natural diet in the wild. Feeding them human food can lead to health problems.

Q: Is it necessary to feed axolotls live food? A: While live food can stimulate natural hunting behaviors, it’s not strictly necessary. Frozen and pelleted foods can also provide a balanced diet, as long as they are high in protein and meet the axolotl’s nutritional needs.
