Well, since the females could be pregnant when you buy them, all male would be better.
Some wild, some pretty, and some whatever.
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.
Yes, you must have a male and female to breed.
if you're trying to breed them, don't worry. he'll catch her
If the fish has a "GONOPODIUM" it is definitely a male.
No benefits.
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. (:
You get a mixed lot of youngsters.
A female guppy can produce up to 1,000 fish in a year if everything is perfect. A female goldfish can produce several thousand ova (say around 10,000) in one spawning.
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.
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!
