You don't "mate " guppies. They do it themselves. Simply place a mature female and a mature male together in a properly set up, heated, filtered tank (minimum size 5 gallon) and feed and look after them properly, and they will do whatever it takes to produce young.
You would need several hundred tanks, and at least 100 line bred fish to start with. Line breeding fish is not an easy or cheap undertaking.
Only buy males or females.
Usually, yes.
Guppies can mate in a community tank of tropical fish around their size. Be sure to add lots of live plants!
No..... you have to have the second half of chomosomes....
Simple answer is yes. Guppies mate and produce young under almost any reasonable conditions. The presence of other fish will not bother them at all provided the other fish are not predators and the guppies under pressure for survival.
No, they are to different types of fish and it would be impossible to breed them.
yes.... thats why hey are called "guppies...."
They can be in a community of other tropical fish of the same size.
