How long does it take for jack dempsey eggs to hatch !!!!!!!!!!?

Question

jack demsey fish a laid eggs in my tank twice the first time the eggs hatched and the this time i want to save them what do i do

Answer 1

It usually takes 3 days.  Once the spawn hatch, the parents move the fry to small holes dug into the gravel.  I eventually replaced the gravel I was using with sand to allow a better substrate for keeping fry.  

Every day the fry are moved to a new hole, until they become free swimming, which occurs in about 10 days.  Parents share duties guarding the spawn and patrolling the general area.  It is interesting to watch how the fish exchange these roles.  

They basically exchange spots in a swift motion, timed such that the fish pass each other at the halfway point.  A bit like a fishy changing of the guard.   Some sources say the young eat slime off the sides of the parents, but I noticed very  little of this sort of activity, in my tanks.  Though the fry may nip at their parents sides from time to time, the fry are not dependent upon parental slime, like Discus are.

Parents will keep fry in a bunch by taking strays in their mouths and returning them to the general school.    

Young may be able to stay with the parents until the males begin to mature, at which point they will need to be separated.  It appears that the parents crush larger food into small pieces and expel it through their gills for the young to consume.

Answer 2

24hrs take the eggs out and put them in a different tank of there own
