danio breeding

[azaazeel]

I have a bunch of danios... but I have never succeeded in breeding them..

this time I have set marble in a breeder tank and i have kept 2 male and 2 preg danio in that tank..

now I want to know after the eggs are layed, exactly how many minutes it take before the male fertilize it.. do they it instantly or it might take a long time.. even if I see the eggs how do i know whether they are fertilized by males or not???

and what time do female lay egg? I mean is it in the dawn or midnight or afternoon...

I think you are way overthinking this.Look man,more than likely after the eggs are laid they will be fertilized if you wanna be really safe leave the males in for a moment or so then take all them out(not the eggs) and put them back into the other tank I assume you have.Or you can do the let nature take its course route and just leave all the fish in til babies hatch..As for time of day the female will do it when she is ready.
