The breeding method of fairy fish

Fairy fish is a kind of tropical fish with high ornamental value, also known as swallow fish, small fin sailing fish, angel fish, small fairy fish, etc., for the angelfish of the Cichlidae family, originated in Guyana, Brazil and other places in South America, there is the laudatory name of "ornamental fish queen", which is almost synonymous with tropical fish. Let's take a look at the breeding method of fairy fish.

The parent fish source of fairy fish

Fairy fish parent fish need to be paired from childhood. Choose healthy fish with strong color contrast and good shape when selecting fish, and raise them since childhood. With regard to the issue of "disability", one should be divided into two. Some disabilities should be resolutely avoided when selecting fish, such as skew of the body, deformation of the head and mouth, and so on, but general injuries such as scales and damaged fins are minor ailments and will not affect the quality of reproduction.

Male and female identification of immortal fish

It is difficult to identify the male and female of fairy fish in the juvenile stage, but the male and female characteristics are very obvious in the adult fish after 8-10 months of sexual maturity. The forehead of the male fish is more developed than the female fish, appears to be full and high, the abdomen is not as swollen as the female fish, and the vas deferens of the male fish are thin and pointed, while the female spawning tube is thick and round. Fairy fish belong to tropical fish that like natural pairing. Successful paired fairy fish often swim and feed together in pairs from the group, living an independent life that only envies the lovebirds but not the immortals.

Parent fish breeding of fairy fish

Fairy fish requires a large breeding box, and to grow broad-leaved aquatic plants, can have several hours of light every day, there are no strict requirements for water quality, like to live in pH6.5~7.0 weak acid soft water, suitable temperature of 26-30 degrees Celsius, like fresh water that has been dried, often changing water will reduce its chance of getting sick. The bait was mainly fed with fresh water earthworms and harvest shrimp, supplemented by copepods and cladocera, and fed three times a day. The feeding amount shall be limited to "seven percent satiety" and the feeding of earthworms will be finished within ten minutes. Usually change water 1/5 every day, the bottom of the box feces and food residue sucked out with a straw, the newly added water is tap water aerated for more than 2 days.

Spawning and reproduction of immortal fish

1. Spawning and insemination: fairy fish have a strong ability to reproduce, laying eggs every half a month or so, and spawning on their own does not need to be spawned. When it is found that the parent fish have precursors of spawning, such as the belly of the female fish is dilated, and even the milk tube is protruding, the spawning board (green thin plastic material) is put down. After the spawning board is put down, the parent fish will soon find and actively brush its surface with their mouths. At the same time, the milk tube of the parent fish continues to increase, reaching the parturient state, the milk tube of the female fish is about 2 mm, and that of the male is about 1.5 mm. The female lays a row of eggs on the spawning board, and the male immediately follows the female and then fertilizes, which is repeated until the spawning is finished, ranging from 200 to 1200 eggs at a time.

2, natural hatching: natural hatching is relatively simple, parent fish do not move after spawning, continue the hatching process, parent fish will take care of fish eggs. In the process of hatching, male and female fish take turns to fan their eggs with pectoral fins, which are close to the water of fish eggs and promote the flow and exchange of water, so that the fertilized eggs have enough oxygen to meet the needs of embryonic development. If it is found that the white eggs, that is, the unfertilized eggs, the parent fish will be pecked out and eaten with their mouths, and the parent fish can be fished out when the young fish hatch out of the plate under the membrane.

3. Artificial hatching: artificial hatching is a common method. When the spawning behavior of parent fish ends, the spawning board will be moved to the incubator immediately. The water temperature and water quality of the incubator and the spawning box are the same and are disinfected with methylene blue solution in advance. At the same time, a small oxygenated pump (or water leprechaun) is set up in the incubator to play the role of splashing water on the fish. During the incubation period, if there are white dead eggs should be sucked out immediately with a straw to avoid infection with water mold, and the temperature should be kept constant immediately.
