Widespread in fresh water of Europe and North Asia, in clean, flowing streams, rivers and clear lakes with a sandy or gravel bottom.
Description
The stone loach is a small, slender bottom fish of the family Nemacheilidae reaching about 18 cm but usually smaller. The elongate, brownish mottled body has a rounded tail, and around the downturned mouth stand six barbels with which the fish searches for food by touch. The species lives hidden under stones on the sand and gravel bed of clean, flowing streams, rivers and clear lakes in Europe and northern Asia, and is regarded as an indicator of good water quality. Mainly at night it hunts insect larvae, small crustaceans and worms. In spring it spawns; the sticky eggs are laid on stones and plants. Because of its small size it has no fishery importance.
