Goldfish
The goldfish ("Carassius auratus") is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is one of the most commonly kept aquarium fish.
Coregonus maraena
In the Baltic basin countries, this species has traditionally been known as "Coregonus lavaretus" (the common whitefish). The name "Coregonus maraena" has been adopted following the suggestion that the name "Coregonus lavaretus" should only be applied narrowly to some whitefish populations in France and Switzerland, as advocated by Kottelat and Freyhof, and repeated by the IUCN and FishBase.
