Gregarious. Found in a wide range of cold and well oxygenated habitats from small, fast-flowing streams to large Nordic lowland rivers and from small upland lakes to large oligotrophic lakes. Usually occurs in association with salmonid fishes. Feeds on algae, plant debris (in rivers), mollusks, crustaceans and insects. Spawns over clean gravel areas in flowing water or on wave-washed shores of lakes. Overwinters in coarse substrate or in deep pools with low current. Migrates upstream for spawning in shallow gravel areas. Important laboratory fish, for research on sensory organs of fishes. Mean maximum age is 6 years. Locally threatened due to pollution and excessive stocking of species of Salmo.
Two aquariums from Southeast Asia: calm forest streams and peat swamps with soft, brown water, and fast mountain streams with cool, oxygen-rich water.
A coldwater aquarium with European fish and plants, without a heater. The water follows the seasons, and summer heat is the biggest problem.
From the store to the tank: how to get the fish used to your water, why you should add only a few at a time, and what to watch for in the first few days.
Why new fish should live in a tank of their own for a few weeks before they move in, what you need, and what to look for.
