How to tell Male & Female Guppy apart?

It is easy to tell males and females apart. The males are a lot more colourful and have an elongated and pointed anal fin called the gonopodium. The gonopodium is used to transfer milt to the female.

Females on the other hand, are a lot rounder, have duller colouration and have a rounded anal fin.

Male guppies grow to around 3.5 cm, females are larger and grow to around 6 cm when fully grown.
