Guppies are livebearing fish, and so they've been bred in captivity so long and so easily that many different varieties have been produced including fantail, lyretail, veiltail and many other long/draping tail varieties. These occur in males and females. generally, the male's tail is larger, but if you compared, say, a male with a small-tail variety and a female of a veiltail variety, the female's tail would be bigger because she's been selectively bred to have the big tail. If you're trying to tell the sex of your guppies, there's an easier way. Guppies are livebreeders and use internal fertilisation, meaning that the male guppy has a penis-like organ known as a gonopodium that he uses to make the female pregnant. It's basically a modified anal fin and is located just behind the pectoral fins. A female with a tucked up anal fin can look like a male until you learn exactly where to look, it takes a while. the gonopodium points back towards the tail and is very thin. Males are often leaner in the body than females also.

Guppies are a community fish and are best kept in odd numbered groups with more females than males; for example, a group of 3 guppies with 2 females and 1 male. The reason for a higher female to male ratio is because males will fight with each other for matting rights to the females.
