How to tell Male and 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.

Breeder Setup



I followed this approach on the setup I have in my fish room:



A: 2 males to 4 females per 5 1/2 gallon tank



B: 3 males to 3 females per 5 1/2 gallon tank



C: 5 males to 6 females per 10 gallon tank.




D: But never one male to one female because it has low success.



E: A father to daughter is the perfect line breed! (Closest Match)



1: Sister to brother is generally what most breeders use today!



2: Always have a second backup set of breeders.




3: One out of every three generations to keep body size.
