It is sometimes hard for the hobbyist to realize that such varied fishes as the koi, barbs, goldfish, danios, rasboras, and American minnows could belong to a single family, but the large family Cyprinidae includes all these types plus many more that are seldom seen by aquarists. Although related to the catfishes and the tetras, barbs lack an adipose fin. The jaws are usually weak and toothless, but there are special pharyngeal teeth located near the gills that serve to tear and grind the food.
Barbels are often present at the corners of the mouth.
The dorsal and anal fins are usually short and lack spines or have at best a spiny ray at the beginning of the fin. Most cyprinids are silvery to tan fishes of medium size, although many exceed two feet in length. With few exceptions, they are egg-scatterers. Because there are so many species of fish in the world there would be no way for one person to be able to research and type the needed information for this massive work in a reasonable amount of time. If you have information to some of these species and possibly others please let us know.
