What to Feed Axolotls: A Guide to Nutrition and Health

Axolotls, often called "Mexican walking fish," are unique and fascinating aquatic pets. Maintaining their health and ensuring their longevity requires a balanced diet and proper care. Here’s a comprehensive guide to feeding your axolotl and keeping it in optimal health.

Understanding Axolotl Nutrition

Axolotls are carnivorous creatures that thrive on a high-protein diet. In the wild, they feed on small aquatic creatures such as worms, insects, and tiny fish. In captivity, you can replicate their natural diet with various high-quality options. It’s essential to ensure that their food is nutrient-dense, easy to digest, and free from harmful chemicals or parasites.

Best Foods for Axolotls

1. Pellets

   • Specialized Axolotl Pellets: These are formulated to meet axolotls' dietary needs and are a convenient option. Look for high-protein varieties specifically designed for carnivorous aquatic pets.

   • Sinking Pellets: Choose pellets that sink to the bottom since axolotls prefer to feed at the tank floor. Floating pellets can go uneaten and degrade water quality.

2. Live Food

   • Earthworms: A nutrient-rich and favorite treat for axolotls. Ensure the worms are sourced from chemical-free soil to avoid pesticides.

   • Bloodworms: Suitable for juveniles or as a supplemental treat for adults. They are small, easy to eat, and rich in protein.

   • Daphnia and Brine Shrimp: Excellent for young axolotls, these small creatures are easily digestible and promote healthy growth.

3. Frozen or Freeze-Dried Options

   • Frozen Bloodworms or Brine Shrimp: Convenient and safe, as freezing kills parasites. Thaw them before feeding to prevent digestive issues.

   • Freeze-Dried Tubifex Worms: These are easy to store and can be rehydrated before feeding to improve palatability and digestion.

4. Occasional Treats

   • Small Pieces of Fish or Shrimp: Ensure they are fresh, free of seasoning, and properly cleaned to avoid contamination.

   • Insects: Feed only pesticide-free insects like crickets or small mealworms. Avoid hard exoskeletons that can be difficult to digest.

Foods to Avoid: Avoid feeding your axolotl fatty meats, large prey items, or anything with hard shells that can cause choking or digestive issues. Additionally, steer clear of live feeder fish, as they can introduce diseases and parasites.

Feeding Tips

• Portion Size: Feed adult axolotls 2-3 times per week, offering enough food to be consumed within 5-10 minutes. Juveniles should be fed daily, as they require more energy for growth.

• Monitor Feeding: Observe your axolotl during feeding to ensure it’s eating properly. Remove any uneaten food promptly to prevent water contamination and maintain tank hygiene.

• Variety is Key: Rotating different food types ensures balanced nutrition, prevents boredom, and helps meet all dietary requirements.

Maintaining and Improving Axolotl Health

1. Tank Conditions

   • Water Quality: Keep the water clean and well-filtered. Perform regular water changes (20-30% weekly) and monitor ammonia, nitrite, and nitrate levels.

   • Temperature: Maintain a temperature between 60-64°F (16-18°C). Avoid sudden fluctuations, as these can stress axolotls and compromise their immune system.

   • pH Level: Ensure the water pH is between 6.5 and 7.5. Extreme pH levels can cause stress and health issues.

2. Enrichment

   • Provide hiding spots like caves, PVC pipes, or aquarium plants to reduce stress and mimic their natural habitat.

   • Keep the lighting dim, as axolotls prefer low-light environments. Use subdued aquarium lights or natural light.

3. Health Monitoring

   • Check for signs of stress or illness, such as lethargy, loss of appetite, floating excessively, or unusual skin changes (e.g., discoloration or lesions).

   • If you notice any symptoms, consult an exotic pet veterinarian promptly for advice and treatment.

4. Avoid Overfeeding

   • Overfeeding can lead to obesity and health issues such as fatty liver disease. Stick to a consistent feeding schedule and avoid offering too many treats.

Common Health Issues and Prevention

1. Fungal Infections

   • Symptoms: White cotton-like patches on the skin.

   • Prevention: Maintain pristine water quality and avoid sudden temperature changes. Isolate affected axolotls and treat with antifungal medications if necessary.

2. Impaction

   • Cause: Ingesting substrate, like gravel, or large food items.

   • Prevention: Use fine sand or a bare-bottom tank to eliminate the risk of substrate ingestion. Offer food appropriately sized for your axolotl.

3. Stress-Related Illnesses

   • Cause: Poor water quality, inappropriate tankmates, or inadequate diet.

   • Prevention: Ensure the tank is properly set up with stable conditions and a healthy diet. Avoid keeping axolotls with aggressive or fast-moving fish that can stress them.

4. Gill Damage

   • Cause: Poor water quality or tankmates nibbling on gills.

   • Prevention: Keep the water well-oxygenated and avoid housing axolotls with incompatible tankmates.

Axolotls are relatively low-maintenance pets, but they require consistent care and attention to thrive. By providing a nutritious diet, maintaining an optimal living environment, and addressing any health concerns promptly, you can ensure your axolotl remains happy and healthy for years to come.

Happy feeding!
