Is peacock fish viviparous or oviparous?

The guppy is neither viviparous nor oviparous, but oviparous. Embryogenesis refers to the reproductive mode of an animal's egg after it develops into a new individual in the mother. Although the fertilized egg develops into a new individual in the mother, its nutrients are still supplied by the yolk contained in the egg itself, and there is no or only little nutritional contact with the mother.

Guppies are easy to sex. Female fish abdomen is larger, in front of the anus there is a transparent fetal spot, in the rapid reproduction of the fetal spot into black. Males have smaller, lanky bellies, and crucially, their anal fins develop copulatory organs for sperm delivery during reproduction.

Guppies reproduce regardless of season, even in winter can also produce normally. Peacock breeding to choose a larger aquarium tank, breeding temperature should be protected at 26-28 degrees Celsius, pH 6.8 -7.4, at the same time to a variety of water plants to ensure the survival of small fish, and then according to the ratio of 1 male to 4 female into the seed fish.

After guppy estrus, the abdomen of female fish gradually expands, black fetal spots appear, male fish constantly chase female fish at this time, male fish's copulatory organ inserts female fish's ejaculatory hole to discharge sperm for in vivo fertilization. Female guppy give birth to 20-40 young fish after four to six weeks of gestation. Remove the female fish immediately after giving birth, otherwise the female fish may eat the young fish.
