Devario auropurpureus ( Latin : “aureus” = golden, “purpureus” = purple) is a South Asian freshwater fish from the subfamily of the danioninae . It is endemic to the Burmese Inle Lake and the adjacent waters.

features

Devario auropurpureus becomes ten cm long and has a very elongated, laterally strongly flattened body. The fish are very variable in color. The basic color is bluish to olive green, the sides of the body are patterned with 14 short, blue transverse bands. The spaces between the transverse bands are golden yellow. The sides of the head are strongly iridescent . The belly is whitish, the fins colorless apart from a few rows of black dots along the fin rays . The fins of the sexually mature males are light yellow to greenish. The author of the first description, the Scottish zoologist Nelson Annandale, described specimens with bright red backs. The dorsal and the significantly larger anal fin are opposite each other. A belly keel is available.

Way of life

Devario auropurpureus lives surface- oriented in swarms on the shores of Inle Lake and in the surrounding ponds and swamps. It feeds mainly on caddis and mayflies and the larvae of these insects. The water in its habitat is relatively hard . Fish kept in aquariums are only pale in color.

The IUCN classifies the species as Endangered . Pollution, the decline in lake area due to droughts, fishing for aquatic purposes and the introduction of invasive species are considered to be the main reasons for the endangerment of the species.

Systematics

The species was described by Annandale in 1918 as Barilius auropurpureus , then assigned to the newly established genus Inlecypris by Howes in 1980 and placed in the genus Devario in 2009 .
