Introduction
Axolotls, often called “Mexican walking fish,” are unique amphibians beloved by hobbyists for their distinctive appearance and regenerative abilities. Proper nutrition is vital to keeping axolotls healthy and thriving. Knowing what axolotls eat ensures they grow properly, maintain energy, and avoid health problems. This guide provides a detailed overview of their diet, feeding habits, and practical care tips.
Understanding the Axolotl Diet
Axolotls are carnivorous and prefer live or fresh animal-based foods. In the wild, they primarily feed on small aquatic creatures, but in captivity, their diet can be supplemented with prepared foods.
Natural Foods
In their natural habitat, axolotls eat:
- Worms (earthworms, bloodworms, blackworms)
- Small crustaceans (shrimp, daphnia)
- Insect larvae
- Small fish (occasionally)
Foods for Captive Axolotls
Captive axolotls can thrive on a combination of:
- Live foods: Earthworms, blackworms, and brine shrimp
- Frozen foods: Bloodworms, daphnia, and shrimp (thawed before feeding)
- Pellets: Specially formulated axolotl pellets, rich in protein
Tip: Avoid feeding axolotls feeder fish purchased from pet stores, as these can carry diseases or parasites.
Feeding Guidelines
How Often to Feed
- Juveniles (0–6 months): Daily
- Adolescents (6–12 months): Every other day
- Adults (1 year+): 2–3 times per week
Portion Sizes
- Feed an amount your axolotl can finish within 10–15 minutes.
- Avoid overfeeding; leftover food can pollute the tank.
Feeding Tips
- Use tweezers or long forceps to deliver food, reducing stress and tank contamination.
- Remove uneaten food promptly.
- Observe eating habits; healthy axolotls are alert and swallow food whole.
Recognizing a Healthy Appetite
Healthy axolotls:
- Open their mouths quickly when food is presented
- Swallow food efficiently
- Maintain a plump, firm body (not too thin or bloated)
Warning signs of poor nutrition:
- Refusal to eat
- Weight loss or thinning tail
- Swollen or pale belly
- Lethargy
If these symptoms persist, consult an amphibian veterinarian.
Where Axolotls Can Be Found or Live
Axolotls are native to lake complex Xochimilco in Mexico City, but habitat loss has made wild populations rare. They thrive in:
- Freshwater lakes and canals
- Cool, clean, slow-moving waters
- Captivity in aquariums with filtered, dechlorinated water
Environment tips for pet axolotls:
- Keep water temperature between 16–18°C (60–64°F)
- Avoid bright light; they prefer dim or shaded areas
- Provide hiding spots such as caves or plants
Common Questions About Axolotl Feeding
Can axolotls eat vegetables or plants?
No, axolotls are strictly carnivorous. Plant matter may cause digestive issues.
Are live foods necessary?
Live foods stimulate natural hunting behavior but are not always required. High-quality pellets can provide balanced nutrition.
How do I know if my axolotl is overfed?
Signs include bloating, slow swimming, leftover food in the tank, or fecal changes. Reduce feeding frequency immediately.
FAQ
1. How do I transition my axolotl from live food to pellets?
- Introduce pellets slowly by mixing them with live or frozen foods. Over 1–2 weeks, increase pellet ratio until fully transitioned.
2. Can axolotls eat goldfish or other small fish?
- Not recommended. Feeder fish may carry diseases, parasites, or chemicals harmful to axolotls.
3. What is the best worm to feed axolotls?
- Earthworms are ideal due to their high protein and easy digestibility. Blackworms and bloodworms are good alternatives.
