Care: Guppies readily accept a variety of flakes,
freeze dried and live foods. Vary their diet for optimum colors and health.
Males are much more colorful and have a modified anal fin that looks like a straw, called a gonopodium. Females are usually a dull grey, have a regular anal fin and are larger than males.
A pregnant female guppy will have a gravid spot. Like many other livebearers,
female guppies can give birth every 28 days and can store sperm so expect multiple drops even if no male is present. They tend to drop groups of 10-60 fry, with older females producing more fry. Parents can and will prey on fry, so it is best to have lots of cover, floating or
grounded, or keep them separate from the adults until large enough to not be eaten.
As most livebearers, it is best to keep guppies in groups of 1 male to 3 or more females.
