Hurt skin, meanwhile, male fish mother fish mutually absorbs liquid, and body generation heat is rubescent, can rapidly promote egg development and give birth to fish-egg, produces
After complete ovum, female fish is caught away rapidly, if do not caught away, they will fight mutually, and female fish can also eat ovum, and female fish catches away it
Afterwards, flowing water above is all closed, then after 12 hours, starts to put a small amount of flowing water, not be fertilized in such 24 hours
Ovum can also supplement a part, keep two days later, decontroling flowing water source, then pay attention to reaction of the public fish in hatching process, according to
The size for the number adjustment nest that public fish comes out in nest, then egg hatching two days later, carries out selecting ovum, during selecting ovum, fish-egg
Connecting together cannot break, and the hatching of fish is facilitated to turn over ovum, then according to the water level height in the big minor adjustment hatching process of fish, water level
Height is higher than two to three centimetres of fish body.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
