If you have guppies in your aquarium or are thinking about getting some, it’s important to know if they are male or female. This is because male and female guppies look different and behave differently. Being able to tell them apart can help you take better care of them and even decide if you want to breed them. In this guide, I’ll show you how to easily spot the differences between male and female guppies.
To tell if a guppy is male or female, look at the size, color, and fins. Males are smaller, more colorful, and have longer, fancier fins. Females are bigger, less colorful, and have shorter fins. Females also have a dark spot near their belly called a gravid spot, which males do not have.

Here’s a simple guide to help you:
1. Look at the Body Shape
One of the easiest ways to know if your guppy is male or female is by looking at their body shape.
- Males: Male guppies are usually slimmer and smaller. Their bodies are sleek, and they have a long, pointed shape.
- Females: Female guppies are bigger and rounder, especially around the belly area. They look more full-bodied, and their shape is more oval.
2. Check the Color
The color of the guppy can also help you figure out if it’s a male or female.
- Males: Male guppies are very colorful. They can have bright shades of blue, red, yellow, or green. Their fins are often decorated with spots, stripes, or other patterns.
- Females: Female guppies are not as colorful. They usually have duller colors, like gray or brown. Sometimes, they might have a little bit of color, but it’s not as bright or as flashy as the males.
3. Look at the Fins
The fins of guppies also give clues about their gender.
- Males: Male guppies have long, flowing fins. Their tail fin (called the caudal fin) is wide and sometimes shaped like a fan. They also have a special fin on their underside called the gonopodium, which is long and pointed.
- Females: Female guppies have shorter fins. Their tail fin is more rounded and not as wide as the male’s. Females do not have a gonopodium; instead, they have a regular fin called an anal fin, which is shorter and more triangular.
4. Observe Their Behavior
Sometimes, you can tell if a guppy is male or female by how they act.
- Males: Male guppies are more active and often chase the females around the tank. They like to show off their colors and fins, especially when they are trying to get the attention of a female.
- Females: Female guppies are usually calmer. They swim around slowly and don’t chase other fish as much as the males do. If a female is pregnant, she might stay away from the males and rest more.
5. Check for the Gravid Spot
This tip is special for females.
- Females: Female guppies have a gravid spot near their belly, just in front of the tail fin. This spot is a dark, sometimes black or brown, area that gets bigger and darker when the female is pregnant. Males do not have this spot.

3. Fins
