Live blackworms are a popular live food for axolotls because they are small, soft-bodied, and move naturally in the water. That movement can encourage feeding behavior in juveniles and selective eaters.
What are live blackworms?
Live blackworms are aquatic worms in the species Lumbriculus variegatus. They are used as live food for axolotls and many freshwater fish.
Are blackworms good for axolotls?
Blackworms can be a useful part of a varied axolotl diet, particularly for smaller animals or axolotls that respond strongly to moving food. They should be offered in appropriate portions and handled cleanly to protect aquarium water quality.
How to store live blackworms
- Place the worms in a shallow container with clean, cold, dechlorinated water.
- Keep the container refrigerated.
- Refresh the water regularly.
- Remove debris or dead material.
- Rinse the worms before each feeding.
Never add the shipping water directly to your axolotl aquarium.
How to feed blackworms to an axolotl
Rinse the worms, then offer a modest portion. Watch the axolotl feed and remove excess food if it begins to accumulate. Keeping uneaten food under control helps protect water quality.
How much should you feed?
There is no single portion that fits every axolotl. Age, size, appetite, body condition, and the rest of the diet all matter. Start with a conservative portion and adjust based on how quickly the animal consumes it and whether food remains in the tank.
Can blackworms be the only food?
A varied diet is generally easier to manage than relying on one food alone. Many keepers rotate blackworms with appropriately sized earthworms or nightcrawlers and quality prepared axolotl foods.
