Preferably, the water had an acidity in the range from 6 to 7, 8 PH and hardness up to 15 dH. Nevertheless, they can feel great in its other parameters. But for reproduction rasbor they must be within these limits.
Clean water is very important for fish of this species. Therefore, predominantly filtering should be present. It is not necessary to use powerful filters, as long as it is in principle. Every week it is necessary to replace a quarter of the water with a new one.

Klinopyatnistye rasbor not very willing to breed at home. Spawning occurs only when there are ideal water parameters in the tank. Future parents need to provide quality food. Suitable age for breeding is from 9 months to a year.
For spawning, it is preferable to move them to another tank with a volume of 15 liters, the water level of which should be from 15 to 20 cm. It is necessary that there should be at least 2 males per female. Water parameters for dilution should be softer, but not lower than 2 dGH.The ideal temperature is about 27 degrees. In the reservoir for spawning, the presence of cryptocrine shrubs or other large algae, which have broad leaves, is mandatory.
Important! For successful spawning the aquarium should be pre-sanitized.
After preparing the aquarium, a female with two males is placed in it. The most suitable time for this is evening. In the morning the fish begin to spawn. Males start flirting with females and hiding with them in algae.
During readiness, the females turn belly up, hiding under a wide leaf of the plant with the male. During this, the females lay their eggs, hiding them under the leaf, which the males then inseminate. Spawning continues for several hours. During this time, the rasbor lay several hundred eggs.
At the end of the spawning season, adult fish are resettled in a familiar reservoir. This should be done so that the adult persons do not eat the fry, which should soon hatch. Fry of eggs appear within 24 hours and after a week they begin to swim. They feed small fish with small foods with a high content of protein - ciliates and egg yolks.The babies are quite fast growing and reach 1 cm by the first month. Before they are resettled to another tank, help the fry to adapt to harder water, gradually increasing the level of hardness in the aquarium where they are kept.
Rasbor are great for home maintenance, especially for inexperienced aquarists. They are peaceful and calm, do not require special skills and are not capricious.
