Well, since the females could be pregnant when you buy them, all male would be better.
Yes, you must have a male and female to breed.
If the fish has a "GONOPODIUM" it is definitely a male.
there is not much difference but it is actually not called a fancy guppy its called a fancy tailed guppies because they have beautiful tails but beware if you have a male and female guppy or fancy tail guppy in the same tank the female will get pregnant and after the babies are born you must separate them or most of the babies will be eaten but beware the babies you can hardly see.
if you're trying to breed them, don't worry. he'll catch her
Depending how old it is, if it is an adult female and it is in with male guppies then it is very likely that it is pregnant. (:

The male guppy will chase thw female guppy, corner her and "show of" which looks like he is shivering before they mate. Keep an eye on the female for a dark ovary spot... you may end up with fries!
yes it would be best to take the male out because sometimes when your not looking he can eat them.
A male guppy will fertilise any female guppy it is in with. Mother,sister, no relation, whatever. It doesn't know and it doesn't care. That is nature.
It might want to mate with it.
All that is needed is a male guppy in with her.
