? Kissing fish are oviparous, and they are all fertilized in vitro. Usually, the female lays eggs first, and then the male ejaculates. When the kissing fish is in heat, the male fish will dance a courtship dance to attract the female fish. When they are paired successfully, the female fish and the male fish will play with each other. When they mate, the male fish will wrap the female fish's body in a U shape and squeeze it. The female fish will lay eggs in the process of squeezing, and the male fish will immediately ejaculate. At this time, the male fish and the female fish have completed reproduction. Because kissing fish do not have the habit of protecting their eggs, breeders should fish them out as soon as possible after they spawn to prevent them from eating their eggs. The eggs of kissing fish are floating eggs, which will float on the surface of the water all the time. The eggs of successfully fertilized fish are amber, and the eggs of unfertilized fish are white. The fertilized eggs can be hatched after one day, and it takes 2-3 days for the young fish to swim.
the kissing fish after breeding? The kissing fish can hatch in about 20-24 hours after breeding. When hatching, the water temperature should be kept at 26 C, and the water quality should be stable. Although they hatch for a short time, they need 2-3 days to move on their own. At this time, the breeder needs to feed them a lot of water to make them grow better.
