Ryukin’s aquarium fish (goldfish): photos, keeping and feeding, breeding and breeding

Ryukin (Carassius gibelio forma auratus, Ryukin) – This type of voile-tailed goldfish is considered the result of the labor of Japanese breeders. She is also called a nymph or riukin.

The body of representatives of this species has an egg-shaped form, crowned with massive fins. The characteristic bend is located on the back, between the fin and the head.

If you take the ratio of height and length of the body, you get a ratio of three quarters to one.

Ryukin fish leads a fairly active lifestyle, so there should be enough space for swimming in an aquarium. For a pair of ryukins, 80 liters of water are sufficient; moreover, representatives of this species are very sensitive to the lack of oxygen, so an aerator is obligatory. Water temperature can vary from 15 to 28 degrees, hardness – up to 20 units, pH 6.5-8.0.

Weekly you need to replace at least a quarter of the water, be sure to plant the plants – Anubias, Bacopa, Valissneria, Elodieus, Echinodorus and others will fit perfectly. The soil should be round and large so that the fish could not dig it. You can not contain goldfish with haratsinovym, tsichlazomami, macro, barbs and other pugnacious fish.

The ryukin ration may consist of dry, live and frozen feed.

Fish reach sexual maturity per year, using one female and two males for spawning. It is easy to determine readiness for spawning: the females have a belly swelling, while males have white specks on their gill covers, and it is interesting to follow the behavior of future producers. In the spawning should be small-leaved plants, large soil.

The female sweeps from 2 thousand eggs, the incubation period is 2 days, on the 5th day the fry begin to swim, they are fed by nauplio of cyclops, Artemia, rotifers.
