These scuds, gammarus, or amphipods serve as a natural food source and clean up crew, promoting a thriving fish tank. These hardy critters will happily scavenge for uneaten food and debris, helping to keep your tank clean and balanced. I like to feed them like I would cherry shrimp. They're partial to algae wafers. The population will grow fast from a small number, many of the scuds that arrive will be paired off already.
