How to breed your own guppy strain methods?

[Njk]

Still pretty new to aquariums and livebearers.

Wondering what the method(s) is to breeding your own line.

Lots of tanks, starting with good lines already. Researching guppy genetics is very important, as is the willingness to cull any that don't meet your criteria. I haven't personally done it like that because I have neither the space or resources and I'm content to just have an ongoing guppy colony in my tank that I add to every so often to keep the inbreeding down.
