Description

The Japanese dwarf pseudorasbora is a small cyprinid endemic to Japan. The species reaches only about 8 cm and has a slender, brownish to silvery body with a dark lateral stripe and a small, upturned mouth. It inhabits shallow, densely vegetated swamps, ditches and slow-flowing waters of lowland wetlands. As an omnivore the fish feeds on small zooplankton, insect larvae and algae. Through large-scale loss and degradation of its wetland habitat the species has declined strongly and is assessed by the IUCN as endangered (EN).
