Quantity of fishes in a pond depends on a saturation of water oxygen, that directly is connected with the area of a surface of a pond.

As optimum conditions of the maintenance fish koi following parameters of water serve in a water tank.

Parameters of water	Optimum value	Critical value
Temperature C	20-28	less 2 more 20
Concentration of oxygen Mg/l	5-30	more 40
pH-water	6,0-8,3	8,5-10,0
Concentration of ammonia Mg/l	less 0,02	0,02-0,1
Concentration of nitrite Mg/l	less 0,1

Pond plant with plants, and in a month when water will be defended also a life will enter into a natural channel, it is possible to start koi. Fishes hard experience resettlement in a new pond and some days are hidden among plants.
Conditions for the maintenance fish koi do not represent any complexities and approach under conditions of our reservoirs. In greater reservoirs with plentiful vegetation when the quantity of fishes does not exceed admissible norms koi to feed it is not required. Koi eat a natural forage of a phytogenesis. Fishes eat larva mosquitoes and other insects, some kinds of seaweed - they are capable to live independently. If you want that fish koi grew also you is better were not afraid - feed up them. Top dressing also is necessary for making at the big saturation of a pond a fish.
At a small reservoir to feed fish koi is better the granulated floating forages, some times in day, small portions. With fish koi it is impossible to overfeed, as it can lead to disease of fishes. Feeding should be carried out in one and too time for a constant place.
