Do you know whether your platy is male or female? It is not difficult to find male platy and female platy separately. Platies are sexually matured after four to five months of their birth. Until they grow, we can’t separate them sexually.
Methods to Identify the Male Platy and the Female Platy
At first glance, the sexually mature female and male fish look similar. But a closer look at their bodies reveals some significant changes.
There are also differences in their color, size, and behavior. All we have to do is carefully monitor their features and posture. That’s the way to know whether is your platy fish male or female.
Step 01: Find the Anal Fin
Male platy and female platy bear a few fins on their bodies. Of those fins, the anal fin is significant from our perspective. An anal fin appears just behind the anus position. Usually, it keeps the fish stable in the water.
Male Platy
Female Platy
If you look closely at the anal fins of a few platies, you will notice that fins come in two shapes. One fin is clamped, flat and elongated, while another fin is mainly close to a fan shape.
The elongated, pointed anal fin belongs to the male platy named gonopodium. The gonopodium is a pointed, sharp structure that helps with copulation and sperm transfer.
The anal fin of the female platy is close to a fan shape.
Step 02: Study the Size and the Shape of the Body
Body size and body shape are the next significant we should observe.
Females have larger bodies than males of the same age. Males are small and thin. Females typically grow up to two inches, while males reach up to one and a half inches.
We will not measure the fish’s length, but we can estimate it.
Step 03: Observe the Body Color
In addition to the facts stated above, I am concerned about the intensity of platy fish body color. If the water quality is good, the male will be brighter than the female.
Step 04: Observe the behavior
All of the facts I mentioned earlier are morphological factors. But we can’t forget their behavioral facts.
The male is quick and exciting and sometimes shows a little aggression. Comparatively, female is calm and less active.
FAQ
Are female platys bigger than males?

Hobbyists only keep female or male platies. Female platies are easier to maintain and more attractive than males.
