It depends what animal it is.
Maybe 24 hours
Before the mating period, the male betta will create a bubble nest, where the eggs will reside. Once the female is near, they will usually fight each other before finally mating. Once they finish, the male will take the eggs in his mouth and put them in the nest. If these are pet betta fish, then the female should be removed after an hour or two.
The male and the female both take turns keeping the eggs warm.
well depending on what type of ant it is regular ants will take about 2 weeks to hatch If the ant is a fire ant it will take about 3 weeks. so very soon
Millipedes reproduce sexually, where the sperm from the male is deposited inside the body of the female to fertilize her eggs. In millipedes, depending on the species, mating can take up to two days. There is a mating season for millipedes, but again, this season differs depending on the species. Males generally rub the female's side with his legs. She responds by tapping her legs around his until eventually the two millipedes intertwine.
18-21 days
the male sea horse has a pouch that it uses to carry the eggs, when mating the female gives the male 1500 eggs
30 days
Maybe 24 hours
After the eggs are fertilized, the female either retreats on her own, or the male chases her off. when this happens, pull her out of the tank and place her in a preprepared "hospital tank" as she will probably have a few torn fins and cuts from the mating process.
The female will do something with her fins and let the male know but when they do mat you have to be right there when it does because the male will kill the female but not the eggs. when the eggs hatch you have to take the male out or he will kill the baby's.

Mating season for the alligator gar is normally during the springtime. However, after mating the male and the female will separate and go their own ways. The female will deposit her eggs and the young fish will hatch with the ability to take care of themselves.
Maybe a couple of days. When it is ready the shell cracks a little bit everyday :)
The eggs take around 60 days to develop inside the female after mating, and a further 60 days to hatch once they're laid.
A female corn snake will lay an average clutch of 12 to 24 eggs about a month after mating - which hatch about ten weeks later.
After mating and building the nest, there is approximately 2-3 weeks before the egg laying begins. Once the female begins to lay, she will produce a new egg every 12-24 hours and it can take up to 2-3 weeks before all the eggs are laid. Once she has laid all her eggs then the incubation period begins and usually lasts about 6 weeks before hatching. Males and Females alternate sitting on the eggs during the incubation period.
