Fathead minnows are omnivores that are categorized as Benthic filter feeders, sifting through dirt and silt to find food. Canadian Journal of Fisheries and Aquatic Sciences, 55, 15–27. The alarm substance is released upon mechanical damage to these club cells due to a predator attack, and can be detected by other ostariophysan fishes which then engage in antipredator behaviors such as hiding or dashing away. These fish are social, active, and moderately hardy. They are in a 10 gal with Red Rili Shrimp and Assassin Snails. Physical description.
