? Mary fish reproduce by ovoviviparous means. When they enter sexual maturity, they will give birth to larvae almost every other month or so. Mary fish are ovoviviparous, and their eggs are fertilized in the female's body. When the fertilized eggs are mature, they can directly produce larvae.
Its breeding process is relatively easy. During the breeding period of about 35 days, the densely planted aquatic plants are put into the breeding box. When the abdomen of the female fish swells and blackens, the male fish is fished out in order to prevent the male fish from preying on the newborn larvae. At this time, we should also observe the changes in the anus of the female fish, if the ovipositor has a falling phenomenon or a punctate protrusion, it will give birth within about 2-5 days. At this time, it is only necessary to put the female fish in the breeding tank alone.
In addition, in order to avoid premature delivery of female fish, attention should be paid not to change water frequently at this stage. Because the water quality changes dramatically, it will directly lead to premature delivery of female fish, which will produce immature larvae, and in serious cases will produce undeveloped eggs.
after breeding? Mary fish must be isolated after breeding. When the female fish gives birth to the larvae, the larvae need to be separated from the female fish for maintenance, otherwise the female fish will chase the larvae to eat.
