Cleaner fish. Cleaner fish are fish that show a specialist feeding strategy [ 1 ] by providing a service to other species, referred to as clients, [ 2 ] by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. [ 2 ] This example of cleaning symbiosis represents mutualism and cooperation behaviour, [ 3 ] an ...
Cleaning symbiosis is a mutually beneficial association between individuals of two species, where one (the cleaner) removes and eats parasites and other materials from the surface of the other (the client). Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other ...

The family is large and diverse, with over 600 species in 81 genera, which are divided into nine subgroups or tribes.

Aquatic ecosystem. An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms — aquatic life —that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and ...
Since the last glaciation, changing water levels are believed to have connected the lake with glacial runoff and surrounding streams and rivers, allowing char to swim upstream into the lake. Arctic char is the only fish found in the lake, and signs of fish cannibalism have been found. [19] Model of a 5.4 kg (12 lb) Sommen charr in naturum Sommen
