Will guppy siblings breed?

Hello, I have three juvenile guppies (one male and two female) who are siblings and I’m wondering will they breed? I suspect they will but I want to make sure that I am correct and I won’t be waiting for baby guppies forever until I realize the guppies aren’t breeding! Also, I’m worried that if they do breed the females will be to young and won’t survive having the fry...Please help me! Thanks!

They will definitely breed yes. Guppies will breed like rabbits regardless of relation.

Without a doubt they will! :p

Yep. They will breed. I'm pretty sure most organisms - particularly animals - can breed with closely related individuals. I think humans are the exception, where inbreeding tends to be negative frowned upon (by society)... and of course, self incompatibilities (common in plants, dunno about animals....) which is biological/chemical.

If you choose to keep breeding make sure to add new DNA every once in a while, otherwise deformities will start to form. This can be as simple as adding one or two guppies.

Guppies would breed you if they could.

As already been mentioned overhere, they´ll certainly breed with eachother. Even in nature siblings will breed with eachother. But mutations like deformities by inbreeding won´t happen so fast in the wild in comparison to captive ones. It´s a fact that guppies are more vulnerable to mutations when kept in captivity. And therefore inbreeding will pace up the deformities in captivity. But they´ll be good for a couple of generations before a deformity by inbreeding happens. Unless the line they came from has already suffered from inbreeding before.
But to create a new strain of guppies, inbreeding is in need. And depending on the traits you´re looking for to be passed on this might be one or multiple times of selective inbreeding.

Almost ALL fish from breederies are inbred and that's why (Partly) in the aquarium hobby they don't survive as long than in the wild. They still won't live as long even if they're wild caught but it is a aspect of why. So they won't become too much worse than they already are and, as stated above sometimes have deformities.

Absolutely they will. There are no incest laws in Guppyland.:)

Yes they will breed. I even came across a study stating that male guppies preferred to breed with their siblings(something like that) but I'm not sure if it's 100% true.

Thanks for the replies :). Turns out I have two males and the third guppy passed :(.

Inbreeding results in higher probabilities of genetic defects passing through, in animals just like in humans.

Sadly or gladly fish never learned certain concepts; like siblings and genetics.
