What Do Axolotls Eat?
Axolotls are carnivores. In the wild they eat worms, small fish, insects, and crustaceans. In captivity, the goal is a high-protein, low-fat diet that mimics this as closely as possible. The good news: axolotls are not picky eaters and will readily accept a variety of foods.
Best Staple Foods
Nightcrawlers (Earthworms)
The single best axolotl food. Nutritionally complete, trigger a strong feeding response, and easy to source from bait shops or garden centers. Always confirm they are pesticide-free. Cut to appropriate size for juveniles — no longer than the width of the axolotl's head.
Hikari Axolotl Pellets
The best commercial pellet option. Sinks immediately, holds together well, and doesn't cloud water. A reliable staple when live or frozen food isn't available. Use as a supplement to nightcrawlers rather than a full replacement.
Repashy Grub Pie
A gel food made in bulk and refrigerated. High protein, no fillers, easy to portion. Popular with experienced keepers as a nightcrawler alternative or rotation food.
Treats (Feed Sparingly)
- Frozen bloodworms: High palatability but low nutritional variety. Limit to once or twice a week at most.
- Brine shrimp: Good for juveniles and enrichment. Low caloric density — not suitable as a primary food.
- Daphnia: Useful as a natural laxative if your axolotl shows signs of constipation.
Foods to Avoid
- Feeder fish: High risk of introducing parasites and disease. Not worth it.
- Beef heart: Too high in fat for regular feeding.
- Mealworms: Chitin-heavy exoskeleton is difficult to digest and can cause impaction.
- Any food with artificial additives or preservatives.
How Often to Feed
- Juveniles (under 4 inches): Once daily.
- Sub-adults (4–7 inches): Every other day.
- Adults (7+ inches): Every 2–3 days.
Axolotls have slow metabolisms. Overfeeding is a common mistake that degrades water quality and stresses the animal. If food is left uneaten after an hour, remove it immediately.
How to Feed Your Axolotl
Use long tongs or tweezers to offer food directly, or drop it near the axolotl and let their natural feeding response take over. Axolotls are suction feeders — they lunge and inhale food rather than biting. Avoid hand-feeding without tongs as they may accidentally bite fingers.
My Axolotl Won't Eat
Refusal to eat is usually caused by incorrect water temperature, stress, or recent overfeeding. See our Axolotl Not Eating guide for a full troubleshooting checklist.
