Description

One of the most popular aquarium fish in the world, the guppy is instantly recognisable to most people. There are many aquarium bred varieties of this species available, most have elongated finnage and gaudy colouration. The wild form is seldom seen for sale.It is advisable to keep several females to each male as males can be quite vigorous in their constant pursuit of females. No real effort needs to be made to breed these fish although a densley planted species tank with lots of floating vegetation is the best way to ensure the survival of the fry.

A pregnant female can be identified by the gravid spot (darkened area) behind her anal fin just behind the belly. Between 5-100 young may be produced from a single female, and gestation takes between 4-6 weeks.

Excess viable sperm can be preserved in the female’s oviduct for a long time.

This means that the females are still able to produce young for 6 months or more if no males are present. Adult fish will eat the young so it is better to remove them after the fry are born to ensure 100% survival. They are incredibly prolific so if you do not want a tank full of fry buy fish of only one sex.https://www.seriouslyfish.com/species/poecilia-reticulata/
