The cyprinid family contains around 1,300 species, widely distributed on most continents of the world. They inhabit all types of waters and adapt readily to various water conditions.
The body shape is conventional, with symmetrical contours, but it may be slender or quite deep, depending on habitat. Cyprinids have seven fins: two sets of paired fins and three single ones. Pharyngeal teeth in the throat grind food before it reaches the intestine. The arrangement of these teeth provides positive identification between similar species.
Coldwater cyprinids include the most popular aquarium fishes of all, the Goldfishes and Koi. Tropical cyprinids are divided into three main groups: barbs, which are like miniature carp, inhabit the middle and lower water levels; danios are faster swimming and prefer the upper levels; and rasboras use all water levels. All cyprinids spawn using egg scattering methods and do not usually exercise parental care.
