Diplomystus (SciiFii)

The American freshwater herring (Diplomystus prairiensis), also known as the American river herring, is a species of freshwater clupeomorph fish distantly related to herrings, alewives, and sardines that originally lived in Wyoming during the Eocene, as an extinct species of Diplomystus, and the genus itself was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern wetlands, lakes, rivers, and ponds across North America to help boost biodiversity. The American freshwater herring is a medium-sized freshwater fish, growing up to be about 65 centimeters (25.5 inches) in length on average. As a carnivore, the American freshwater herring feeds primarily on smaller fish and aquatic insects (including aquatic larvae of terrestrial insects). A very peaceful shoaling species, American freshwater herring can be skittish and timid if left without any kind of shelter, and if kept in isolation they tend to become reclusive. Living in a shoal, given plenty of room to move and provided with cover behind which they can hide if they feel threatened, they do very well in the wild and in captivity. They are peaceful enough to be trusted with fish around the size of themselves, and robust enough to cope in the company of much larger fish. The conservation status of the American freshwater herring is Least Concern due to successful conservation efforts and the American freshwater herring's wide range.
