Range & habitat
Nannoperca obscura occurs in the coastal drainages of southeastern Australia, preferring streams and lakes with plentiful vegetation and flowing water. It is found only in the southeastern portion of South Australia south of Adelaide, and extending along southern Victoria some way past Melbourne. The species was first reported in the lower Murray reaches in South Australia in 2002. However, the 2008 millennium drought caused local extinction in the Murray-Darling basin, with only a few individuals kept in private dams.
