how many days does it takes for de eggs 2 hatch??

Temperature plays an important factor. Usually, at temps between 20 - 24 deg. C., it will take about 2 days.

Shortly before hatching, the embryo makes violent movements inside the egg shell. These movements, aided by an enzyme which softens the shell, enables the fry to break free. The tail emerges from the egg shell, followed by the head. The most prominent feature is the yolk sac.

The fry hang by a stcky secretion to any firm surface; during this period the yolk sac is consumed. After about another 2 days the fry will manage to struggle to the surface and the tiny air bladder will become inflated. From that stage the fry become free-swimming and will begin their hunt for food.

It can take longer- 5 days- in cooler temps. Interesting that if the heat is raised immediately prior to hatching there will be a higher male fry ratio born. Conversely, a sudden drop in temp will produce more females.

It has been hypothesised by many breeders that eggs that hatch in temperatures greater than 70F (less than 4 days) have more incidence of poorly formed or developed fry. The number that successfully hatch is also lowered.

Eggs that hatch in cooler water (68 or less) will take much longer (5 days plus) and run a much greater risk of fungus taking large numbers of them.

Most fancies do well at exactly 70F for 4 days. The single tails and "less fancy" varieties do better at about 68F and 3-4 days.

That is interesting about the sex - I have never heard that! Cool. :)

That is fine :) . They don't move until they have shaken off all the egg sac. You do not need to feed them until they are free swimming- about day 3. They are eating the egg sac they have emerged from before that.

You need to get them some baby brine shrimp. This is the best food to feed fry for the first month. You can buy frozen or hatch your own. Hatching is cheaper.

Congratulations on your fry :D . I suggest you read up on some threads in the breeding forum here at kokos to learn more about their needs and how to care for them. You will need a sponge filter for example.
