The Isaza goby (Gymnogobius isaza) is a freshwater fish of the family Gobiidae that grows up to 7 cm.
Description
The Isaza goby is a small goby endemic to Lake Biwa in Japan. The species grows to about 7 cm and has a slender, partly translucent, silver-grey body. Unlike many bottom-dwelling gobies it lives largely pelagically: it schools in the open water of the lake and feeds on small zooplankton, with a daily vertical migration. Owing to decline of the lake the species is vulnerable. The fish is harmless to humans. The IUCN has not evaluated the species.
