Minnow-nase, or Chondrostoma phoxinus, is a small freshwater fish from the carp family. It lives in clean rivers and streams of the Balkan Peninsula and feeds on algae.
This species differs from related kin by its small size and mouth shape adapted specifically for scraping algae. It is important for nature because it controls algae growth in rivers and serves as feed for predatory fish.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
Immature form that undergoes metamorphosis before adulthood.
