Black Worms

These bacteria-infested worms are among the best sources of protein for the fish and are an excellent conditioning food for breeding preparation. But be careful, frequent feedings will cause the fish to become fat and impair breeding. Because black worms are generally collected or raised under non-sanitary conditions, diseases are far more likely on a steady diet of worms. Thoroughly rinse worms in chlorinated water (tap water) before feeding to your aquarium fish.
