guppy fertilized? After the guppy is in estrus, the abdomen of the female fish will gradually expand and black fetal spots will appear. The male fish will chase the female fish constantly and insert the copulatory organ into the cloaca of the female fish to discharge sperm for internal fertilization. Female fish can store sperm for later fertilization. Pregnant females are characterized by black triangular patches between the anal and pelvic fins.
after fertilization, guppies can give birth to small fish babies about a month after fertilization, and the time is relatively short. Generally speaking, the breeding interval of guppies is about 25 to 30 days. Guppy females will have some characteristics when they are about to give birth. For example, the female fish that will give birth will have some black spots on the lower abdomen. And when they swim, they have a very unbalanced look, and they feel like they are drunk. Whether the female fish produces immediately can be judged according to the above characteristics.
male and female guppies? Female guppies have a larger abdomen and a transparent fetal spot in front of the anus, which turns black when they are about to reproduce. Males, on the other hand, are characterized by a small, slender abdomen. Crucially, the anal fin has evolved a copulatory apparatus to transport sperm during reproduction. Several rays of the anal fin of the male fish are also relatively large.
