Welcome to the secret weapon of professional fish keepers. California Blackworms (Lumbriculus variegatus) are widely regarded as one of the most nutritious live foods available for the freshwater hobbyist. Unlike frozen or flake food, live blackworms trigger a natural predatory instinct, ensuring even the most “finicky” fish receive the calories they need.

Why Choose California Blackworms?

• Nutritional Powerhouse: Packed with high-quality proteins and essential fats, these worms are perfect for rapid growth in juveniles and egg production in breeding adults.

• Safe & Clean: Our worms are rinsed and treated before packaging to minimize the risk of introducing pathogens into your display tank.

• Irresistible Movement: The wriggling motion of live worms is a visual dinner bell for species like Discus, Angels, and Pea Puffers.

• Survival in Substrate: Unlike some live foods that die quickly, any blackworms not immediately eaten will often burrow into the substrate, acting as a “living snack” for bottom dwellers like Loaches and Corydoras.

Beginner’s Guide: How to Care for Your Worms

Managing live food might seem intimidating, but blackworms are incredibly hardy if you follow these three steps:

1. The Rinse: Upon arrival, empty the worms into a shallow plastic container. Rinse them with cold, dechlorinated water until the water runs clear.

2. The Fridge: Store them in the refrigerator with just enough water to barely cover them. They need to stay cold to slow their metabolism.

3. Daily Maintenance: Change the water once a day. This removes waste and keeps the worms fresh for up to a month.

How to Feed

Use a feeder cone or a pair of feeding tongs to drop small clusters into the tank. Feed only what your fish can consume within a few minutes. For bottom feeders, simply release them near the substrate.
