How a long-lost fish species was brought back to Bendigo

The southern pygmy perch hadn't been seen in Bendigo Creek since the mid-19th-century goldrush, when a booming town sprang up around the central Victorian waterway. This attractive small fish, which displays bright colors when breeding, is no more than 6–8cm long. Once widespread, the species eventually became locally extinct across the Loddon River catchment, which includes the creek.
