Who is the father fish for guppies when there are multiply sexes of fish?

I have a 29 gallon tank with 3 male guppies and 2 female guppies. how do i know which on is the father, and can they all be the father?

You need more females for a healthy tank, generally 1 male to every 3 females is the ratio to shoot for.
Male guppies are horn dogs and will harass a female pregnant or not. That’s why more girls is better, to give them some down time. A female can delay the development of her embryos for up to 6 months, allowing her to have fry months after no males are present.
Basically any of the three could be the father as well as any males they were raised with before you got them. They can have multiple fathers for one batch of fry. You can’t really tell who the father is for these little guys.Best of Luck!

    There’s no way to tell. If the fry are the same color as one of the males then it would be likely that he is the father, but that’s not a sure thing.

    Only one is the father, but the only two ways of finding out is the vet or waiting for your fry to grow and compare their genetics. :)

  4. Yes they can all be the father. Female guppies hold multiple packets of sperm. Each bag has a limit and if everybody is adding to the mix, everybody has a chance of being daddy.

    It’s one sperm per egg, but they could all be different. That’s the way mother nature dealt the cards.

    With guppies the female can store sperm for several months so it could be any male she’s been in contact with over the last 3-4 months, possibly longer.
