Smallest fish [Freshwater]
Last updated: October 13, 2017 at 18:43 pm
The sleeper goby (Leptophilypnion pusillus) has a maximum standard length of 9.1 mm (0.36 in)—with males of the species being even shorter—which makes it the smallest fish in the world (freshwater & marine). The genus Leptophilypnion is endemic to stagnant or slow-flowing shallow water in the Amazon Basin. Mature females of Paedocypris progenetica, a member of the carp family discovered in an acidic peat swamp in Indonesia in 2006, grow to 10.3 cm (0.41 in). The pygmy goby (Pandaka pygmaea) has a maximum length of 11 mm (0.43 in). It is found in streams near Luzon (Philippines).
