📖 Overview

Amphidromous freshwater species . Inhabits fast flowing parts of rivers that have rocky substrates and usually associated with rainforest zones . Adults apparently spawn in fresh water but the larvae are carried downstream to the sea, metamorphose and migrate back upstream, this cycle explaining the presence of small specimens in coastal waters . Maximum observed standard length 6.63cm . Seems evasive and difficult to catch .
