Axolotl Food Types Feeding Schedule Guide: Worms Pellets Shrimp
Axolotls are obligate carnivores with a feeding response triggered by water-borne scent cues and movement. Get the diet wrong and you cycle through impaction, malnutrition, fungal infection and behavioural decline within months. Axolotl food types matter more than they do for almost any other amphibian because the species evolved on a narrow protein-rich aquatic diet — fail to replicate it and the animal slowly starves on inappropriate substitutes. This guide from Gensou Aquascaping at 5 Everton Park covers the protein hierarchy, feeding frequency, and the axolotl food types that consistently produce thriving long-lived axolotls in Singapore conditions.
The Protein Hierarchy
Wild Ambystoma mexicanum eat insect larvae, small fish, crustaceans and worms in Lake Xochimilco. The captive equivalent ranks roughly: live blackworms (top tier), live or sectioned earthworms (top tier), Repashy Grub Pie or Soilent Green (excellent), Hikari/Sera Salamander pellets (good), frozen bloodworms (treat only — low calcium-phosphorus ratio), brine shrimp (juveniles only), feeder fish (avoid — disease risk and thiaminase content).
Live Blackworms
Blackworms (Lumbriculus variegatus) are the gold-standard axolotl food. High protein, balanced amino acid profile, and the natural movement triggers strong feeding response. Singapore aquarium shops sell live blackworms at SGD 8-15 per portion. Rinse thoroughly in cool dechlorinated water before feeding to remove any decomposed worms. Store in a refrigerator at 4-8°C with daily rinsing — a portion lasts 7-10 days. Browse the live food section for current stock.
Earthworms (Sectioned for Adults)
Common European earthworm or red wiggler is excellent adult axolotl food. Buy from organic compost suppliers or grow your own bin — never use worms from HDB or industrial soil because of pesticide and heavy metal contamination. Cut adults into 2-3cm sections matching the axolotl head width. Feed two to three sections per adult, twice or three times weekly. Whole worms are too large for most axolotls and trigger spit-out reflex.
Repashy Gel Foods
Repashy Grub Pie and Soilent Green are powdered gel foods that mix with hot water to form a firm jelly. Cut into small cubes for sinking feed. The formulation is calcium-rich, vitamin-balanced, and accepted by most axolotls within 2-4 attempts after weaning. Repashy is particularly useful for keepers who cannot source live food consistently. Cubes sink and stay intact for 30-60 minutes — uneaten portions must be removed to prevent water fouling.
Pellet Foods
Hikari Sinking Pellets, Sera Salamander Pellets and JBL Novo Tab Fix all work as supplementary food. Pick soft sinking varieties — never floating pellets, which trigger gulping and air swallowing. Pellet diets alone produce thinner, less robust axolotls; use pellets as 30 per cent of total diet maximum. The convenience suits travel weeks but should not become routine.
Foods to Avoid
Frozen bloodworms have the wrong calcium-phosphorus ratio for long-term feeding — use as occasional treat only, less than 10 per cent of diet. Feeder goldfish and other tropical fish carry disease and contain thiaminase that degrades B-vitamins over time, leading to neurological symptoms after months of feeding. Beef heart spoils water dramatically and is overly fatty. Mealworms have hard chitinous shells that contribute to impaction.
Feeding Frequency
Juveniles under 8cm: daily, small portions sized to head width. Subadults 8-15cm: every other day, slightly larger portions. Adults 15-30cm: 2-3 times weekly, two or three earthworm sections or equivalent. Adults bulk easily on overfeeding — a healthy axolotl has a flat-topped body without ridge of spine showing. Visible body fat folds indicate overfeeding.
Feeding Method and Tools
Drop food directly in front of the axolotl using long aquarium tweezers or a turkey baster. Many axolotls become hand-feedable within weeks — they associate the keeper’s silhouette with feeding. Feed at lights-off when activity peaks. Remove uneaten food within 30 minutes to prevent ammonia spikes. The chiller-cooled water slows decomposition but does not stop it. Pair feeding with regular water testing to catch parameter shifts early. Healthy adults fed correctly live 12-15 years in Singapore captive conditions.
