Description

The weatherfish is an eel-like bottom fish of the family Cobitidae reaching about 30 cm. The elongate, yellow-brown body bears dark longitudinal stripes and around the downturned mouth stand ten barbels, with which the fish probes the mud for food. The species lives in muddy, vegetation-rich ditches, marshes, moorland pools and floodplains of central and eastern Europe. It is remarkably hardy: when oxygen is short or in drought it gulps air at the surface and uses it for breathing in the gut, and when waters dry up it burrows deep into the mud. Because it becomes restless as air pressure falls before a storm, it is called the weatherfish. In the Netherlands the species is protected and has declined.
