Caring for and culturing Gammarus

Gammarus, or scud, are a freshwater shrimp that are easy to raise and make terrific food for all kind of fish. Gammarus can be cultured in a shallow container. Duckweed growing on the surface provides an excellent food source as well as habitat for the shrimp. They feed well on algae but also enjoy a piece or two of lettuce in their tank to munch on.
Aeration does enhance the culture but, as with daphnia, should be very low; 1 bubble per second seems to work well.
Gammarus can also be used in science fair projects investigating movement or survival of invertebrates.
