Live Black Worm Culture

Give your fish the best with our live Blackworm cultures—nutritious, natural, and irresistible to a wide range of species. Blackworms (Lumbriculus variegatus) are a high-protein live food that stimulates feeding responses and supports healthy growth in Bettas, nano fish, fry, and other freshwater favorites.

At Scallywag’s Fish Bowl, we culture our Blackworms in-house for maximum freshness and quality. Whether you're boosting color, encouraging breeding, or raising strong fry, our Blackworms are a go-to choice for dedicated hobbyists.

Each portion is harvested fresh and shipped with care, backed by our Arrive Alive Guarantee.  There are approximately 50 worms in a quarter-size portion.
