A tiny minnow that lives only in Oregon backwaters is set to become the first fish ever taken off U.S. Endangered Species Act protection because it is no longer threatened with extinction.

The U.S. Fish and Wildlife Service announced early in February that it was proposing to realist the Oregon chub as recovered, 21 years after it went on the endangered species list.

The fish will be monitored to make sure populations continue to grow.
