Culturing

Black worms are much more difficult to culture than most other forms of live food, however they can be cultured with some success in a 10 gallon aquarium. A substrate such as brown paper towels can be used for the worms to live in and eat once it starts to decay. Aeration is required, and water level should be kept to a few inches to maximize the amount of oxygen in the water, since worms will live on the bottom. It is often difficult to achieve the same amount of yields as other forms of live food, but they may reproduce asexually under these conditions. However, the possibility of keeping the worms with another live food such as also culturing daphnia int he same container makes the effort of culturing them much more bearable.
