The Bärblinge (Danionidae) are a species-rich and widespread family of the carp-like ; They get their German name from their resemblance to the barbel . Often they are small fish of just 2 to 3 cm, up to a maximum of 10 cm in length. They are mainly schooling or at least group fish. Bärblings live in Africa and in South and Southeast Asia, including the islands of the Philippines and Indonesia , and southern China ( Pearl River only ). One species, Barilius mesopotamicus, is found in the Middle East . Most of the species live on the Indian subcontinent and in Southeast Asia . There are species that only live in calm rivers and ponds, but there are also species that live in lakes or rivers. Some species of the danio fish are popular aquarium fish, including the model organism zebrafish ( Danio rerio ).

features

Bärblings differ from all other types of carp in the position of the lateral line organ . It is bent downwards in them and runs on the tail stalk below the middle. The mouth of most danios is slightly above. The dorsal fin always begins behind the pelvic fins and has two to three undivided fin rays and 6 to 16 divided ones. The anal fin is short and has 5 to 17 split rays. The belly of the Bärblinge is rounded, never keeled. Most species have no barbels ; if they are present, they are relatively long.

Systematics

The Bärblinge were introduced as a taxon in 1863 by the Dutch ichthyologist Pieter Bleeker . For a long time they were considered a subfamily of the carp fish (Cyprinidae). Stout and colleagues raised all subfamilies of the Cyprinidae to family status in 2016. The scientific fish database Catalog of Fishes took over this and now manages the Bärblinge as well as the other former subfamilies of the Cyprinidae as independent families. The former tribe of the Bärblinge now have the rank of subfamilies.
