What is the Difference Between Male and Female Guppies?

Male vs Female guppies how to identity?

Are you wondering whether your guppies are male or female? How do you tell if a guppy is a boy or girl?

Fortunately, it’s very easy to tell the difference between a male guppy and a female guppy.

Unlike some fish, such as goldfish, where the differences between males and females are quite subtle,

Male guppies have a very different appearance from female guppies, which makes them easy to identify from others.

What do male guppies look like?

Male guppies have big colorful tails and fins and usually some color on their bodies.

A huge variety of colors are available, including red, orange, yellow, green, blue, or a mix of different colors.

Males are smaller than female guppies.

Not just in terms of length (where females can be up to twice as long)

but also in terms of how deep or stocky their bodies appear.

The females look much bigger and bulkier.

As if the size and color of a male guppy didn’t make it obvious enough.

The anal fin of the male is also very different from that of the female.

it is situated just below the tail and – in males – is long, thin, and pointed.

What do female guppies look like?

Female guppies are much less colorful than males.

Females usually have pale gray or silver bodies and equally drab fins.

A pale color such as a light yellow is about as much coloration as you are likely to see in a female guppy.

As previously mentioned, females are also much larger than male guppies.

This difference in size can be seen from a very young age.

Unlike the male anal fin, which is long and pointed, the female anal fin is a triangular shape.

Also, female guppies often have a dark spot just above the anal fin.

This is called the gravid spot and is visible whenever a female guppy is pregnant.

As female guppies are almost always pregnant, this spot is usually visible.

The size and darkness of the spot indicate how heavily pregnant the guppy is, as the spot grows larger and darker as the guppy gets closer to giving birth.

So how do you tell a male guppy from a female guppy?

How to identify male and female guppy?

To tell a male guppy from a female guppy, you should look for the following signs:

  • Color: Is the fish very colorful? If so, this suggests it is male. Bland colors suggest a female. In
  • Size: Is the fish quite large (over an inch long) with a heavy-set body? This suggests a female. Males are smaller and more slender.
  • Anal fin: Is the anal fin long and pointed? This means that the guppy is male. Females have more fanned-out, triangular anal fins.
  • Gravid spot: Is there a dark spot just above the anal fin? Only pregnant females have this spot. So if you see a gravid spot, you know the guppy is definitely female.

Now that you know how to tell the difference between male and female guppies, why not check out this post on how many male guppies you should keep for each female?

Female guppies are almost always pregnant and display the black “gravid” spot for most of their adult lives.

You really have to see a female guppy pregnancy for yourself before you start to learn from experience just how heavily pregnant the guppy is.

That said, you may notice the female start to appear particularly square and boxy shortly before giving birth and the black spot really will be very large and dark.

(In some cases, you can even spot the baby guppies through the partially see-through female’s body when she is very close to giving birth!

However, this isn’t always the case, so shouldn’t be relied upon.)

The best thing to do is keep a very close eye on your guppies and really try to examine and remember the stages that the female goes through.

That way, when the next pregnancy comes along, you’ll have a much better idea of what to expect.

Do guppies change gender?

No, guppies cannot change their gender, while buying look for visible signs,

The males have a stick like gonopodium where the females have a fanned anal fin.
