Cyprinidae is a family of freshwater fish, commonly known as Cyprinids. A species-rich family with representatives in Europe, Asia, Africa and North America. Cyprinids are found in almost all water types and areas except the high mountains. Some species like still or slow-flowing water, while others prefer fast-flowing water. The body shape is usually elongated round to oval. The fins are generally small and always week-rayed. Fin enlargements are rare. The mouth opening is in many cases facing a bit down to scan the bottom with the help of thick lips or barbels. In some species, the mouth can also be protruded trunk-like. Cyprinids do not have real teeth, but do have horny throat teeth.


In general, the smaller Cyprinids are excellent aquarium fish. They are tough in captivity, undemanding and peaceful. There are almost no real predatory fish in the family. Most species like to live in company and join together more or less in larger groups. They are therefore generally particularly suitable for the community aquarium. They can bother quieter fish and are best kept with similar fish.


The food requirements are quite small. With a few exceptions, most are omnivores. So there are no problems and the fish can be fed very varied. The habit to gobble has an annoying side effect. Due to the spreading dirt, finely feathered plants can be covered with dirt with all the negative consequences (algae). The bottom must therefore be kept clean.

Breeding Cyprinidae

Breeding Cyprinids does not usually cause any problems. Most species are egg scatterers, that is, the eggs are simply spread through the aquarium after heavy hunting. In some cases, the eggs are also attached to plants or the like. Breeding care only occurs in a few cases, so the parent animals must be removed after the eggs have been laid. In addition, it is wise to protect the eggs from eating in certain cases. Grids or pebbles help. The eggs take 1-2 days to develop. After hatching, the larvae hang on the glass or plants for a few days. Then they go swimming freely and they have to be fed fine dust food.
