How To Tell If A Goldfish Is Male Or Female: Top 6 Methods For You

There are many ways to determine the difference between males and females. Here are some of the most common methods for telling if your goldfish is a boy or girl! Let’s scroll down to know quickly!

1. Check For Breeding Stars On Gills, Body And Fins

Did you know that your betta fish has breeding stars on their gills, body, and fins? Well, let us explain for you!

If you have a goldfish, you may notice small white spots on its body. These are ich or white spots called “Breeding stars” ( another name you can call “breeding tubercles”). You may also see them on the chest (frontal) fin’s front rays and even on the body’s scales!

Some people believe that breeding stars appear when your fish is stressed from overcrowding, poor water conditions, or sudden temperature changes.

Still, some are supposed that breeding stars are to “drive” female goldfish during mating season. If your fish has white spots like that, it will be a male. But keep in mind, not all males have breeding stars because they depend on their age and habitat where they live.

2. Check The Vent Shape Of The Fish

The vent is the posterior opening through which it defecates, reproduces, and lays eggs. This area can be used to identify the gender without having to kill or injure them.

On the surface, examining a fish’s vent might seem like an odd way to determine its sex. But as it turns out, this is usually accurate and can be done in just a few seconds!

The vent shape on most females is round or oval-shaped, while males have an oblong shape and are longer than females.

However, this method will have a high percentage is accuracy if you are a professional in identifying the sex of your pets.

3. Study The Body Confirmation

Another strategy to determine if your tiny friend is a lady or gentleman is that you can see its shape and body. This method is not true one-hundred percent, but you can try to look from above to examine the shape of your pet fish with ease.

What’s the result? Well, you can recognize females will be rounder and thicker than males, particularly their belly site. This is because when the mating season approaches, they might be exceedingly fat, bulging with baby eggs, making their body not balance from their two sides.

On the other hand, males are longer and slimmer because they don’t keep eggs like females.

4. Look At The Shape And Length Of Front Fins

Coming with this step, you can see the shape and length of the front fins clearly with your naked eye. The front of a lady fish is usually shorter than a gentleman counterpart.

Still, your observing process and telling whether your pet is a boy or a girl will succeed when they are the same breed and grown up together. Keep reading! The following useful information is waiting for you!

5. Watch The Fish For Signs Of Mating Behavior

When the mating season is upcoming, you can identify some of the signs, especially the mating behaviour of your pets. By the way, this is the most efficient way to recognize the gender of your pet fish. Remember the best time to do this is the peak season of the mating stage.

In detail, males will be the “catchers” and then follow females closely under their tummies or behind them, bumping and occasionally shoving them into objects or plants in the same tank.

While females will be on the move and may become exhausted or have ripped fins during this time. Thus, when two fish keep together in one tank, you can apply this strategy to identify their gender.

Which fish will flutter or rush around the tank is male, the remaining one is female goldfish.

6. Observe The Fish Momentum

We can look at your pet momentum in the previous section to tell if your pet is a “woman” and a “man”. This characteristic is a result of the behaviour of the breeding season.

In particular, before reducing, most females tend to swim slower than male goldfish. To recognise the process successfully, we recommend you combine both momentum and the features of your pet fish in the breeding stage! Take a chance!
