Perch

From this group the aquariumists successfully conduct two types of American perches — diamond and disc-like, and also native indo-chinese — glass perch.The American perches dwell in the net, transparent waters rich in oxygen. They well feel in aquariums capacity from 30 litres and more with the cool water and sandy soil. At the drop in temperature on 10єS become nonactive, experiencing this the «winter», as well as in nature, in the half asleep state. At temperature from the 15єS fish become active and are able to spawn. The range of temperature condition for perches is great, that allows to experience our winters them even in the opened pools. They prefer hard water, are undemanding in regard to the reaction of environment, but badly carry the volte-faces of temperatures, composition of water and lack of oxygen.Before landing on spawning the separate maintenance of raznopolih fishes is recommended. For them the anxiety about posterity is characteristic, which is assumed by male. Before ikrometaniem it digs up in sand pit which development of caviar and larvae under the vigilant supervision of male is in. Delete a female after ikrometaniya. Ripening of caviar takes place during two days. The larvae become freely floating fries in 4—5 days, whereupon usually transplant male. However its anxiety about posterity can last and long, so that, unless necessary in saving of maximal quantity of molodi, interestingly ponablyudat after the further development of relations in family of father-lone person.

Diamond perch

approximately about 6 sm grows in the aquarium terms, in the natural reservoirs about 10 see Body of this fish of uploshennoe, high. ON the brownish background the great number of brilliant dark blue-green points is sparse. Females more shallow and are painted paler.

Disc-like perch

is characteristic to its rounded off, in type by the oblate from sides body painted in the brownish tones with the dark transversal bars.

Glass perch

is taken by zoologists in the special family. Motherland of this fish — indo-chinese. One of originalneyshih fishes with the shortened, high, compressed from sides transparent body. At the young fishes it almost colourless, with age adopts a goldish tint with the bluish reflection on the tail part of body and on plavnikah. Fish is so transparent, that through its fabrics examine with x-rays a spine and air-bladder Temperature of maintenance room. Spawning -26—28 °The S. Razvitie caviars the about days flow, larval stage — two days. In spawning-ground water level 18—20 see Rear the fries by kolovratkami after «dust». The producers eat a caviar up. Is considered necessity round-the-clock to light the spawning-grounds by the dim dissipated light and poorly blow through an aquarium with molodyu for creation of insignificant interfusion of layers of water. Basic difficulty in breeding — saving of fries on the early stages of growth. The pubescence comes about 6 months, life-span a 3—4 year.
