Male Vs Female Betta: Personality And Other Differences

Bright, colorful, and exquisite – these words are not enough to express the beauty of betta fish. And maybe that’s the reason why they are the top picks among aquarists. 

However, there are some significant differences between the male betta and the female betta. But why should you bother about the difference? 

Well, gender decides the personality of bettas. The male betta is very aggressive, making it unsuitable for community tanks, while the female betta is a bit docile. 

Besides personality, there are other differences between the two. Continue reading to find out more about their differences to bring the right betta fish home.

Male Betta Vs Female Betta: Personality

Betta fish has its roots in the South Asian region in the Mekong river, where it earned its name as the Siamese fighting fish. It was bred to fight for gambling purposes.

This species is fierce and provincial and attacks anything that comes too near. Though both sexes have inherited aggression due to sexual dimorphism, there are some evident traits exclusive to each.

Come, let’s learn about them in detail!

Male betta Splendens are extremely aggressive and become combative at the sight of other bettas, especially in their territory. They flare their gills and fins to symbolize dominance over others for region and females.

When a male betta is in proximity to other fish, usually with a similar personality, it rages out in aggression leading to the death of one or both fish.

The constant urge to capture territory makes them anxious and unhealthy. It could be a splendid sight as a viewer but repeated flaring of anger can lead to stressed, sick fish. 

On the contrary, aggression is not a major temperament in female betta fish, and they are cordial with other betta fish. If you want to house more than one betta fish, a community can be set up with other congenial fish or female betta fish.

Male Vs Female Betta Personality

They will likely co-exist with one another in betta sororities, provided they get ample space and decorations like plants, rocks, and other aquarium props to hide. But please ensure not to overcrowd the tank at once.

In captive breeding, the male bettas are kept alone because their violent temperament makes them timid and nervous. They often get stressed when they see their reflection and react to it with anger too.

The chirpy and curious female bettas are often foundto be playful with their housemates in the tank. They might be less bright than their male counterparts but attract all the attention with their high spirits.

The male betta fish are emotional creatures even though fish lack emotional intelligence. They demand attention from their owners or the one who feeds them, as they do not generally interact with other fish. They become more active and light-hearted in their presence.

Talking about female betta fish, they are more independent and less lonely. Their lively instincts make them bubbly in the aquarium. Though the female bettas are less fierce, picking compatible in-mates is of utmost importance. Bottom dwellers or tiny aquatic species are generally the best tank mates for female bettas. 

You will notice that when the male betta fish flares, their head posture isn’t down, but the female flares by swimming in a head-down position. This is again a reflection of their personality difference. 

Other Key Differences: Identify Your Betta Splenden’s Gender

The male and the female betta’s personalities do not resonate with each other, but there are more differences than that. The different physical characteristics will help you easily distinguish between your male and female bettas.


The male betta usually has a steady box-like body and is pointed behind the head portion. Male betta fish are leaner and larger and have bright-colored scales.

With a large belly, female betta fish are plumper than male betta fish. They are also colorful fish but compared to the male bettas, female bettas are dull in appearance.

These fish tend to lose their brightness when they are unhealthy or stressed in their environment. Proper care and suitable water conditions can help in avoiding this situation.


The most evident difference between the male and the female betta fish is the shape and size of their fins.

Male betta fish have longer pelvic and dorsal fins. The anal fins are thicker and angled so that they can flex for the illusion of being more elongated.

Female betta fish have shorter and skinnier fins. The small fins enable them to be more agile and active than the opposite sex as they need to drag lesser weight.

Egg Spot

The white spot under the belly between the ventral and anal fins of female metta fish is the egg spot. This spot is the ovipositor tube to lay eggs.

Egg Spot

The male betta fish do not have these egg spots. The male fish care for the babies by protecting them in the bubble nest that they create. Once the eggs are laid, the male pushes the female betta fish away.


The membrane beneath the gill of the male betta fish is often considered a beard. They glare at the beard when they feel threatened in their region to show dominance and frighten the opposition.

The female betta fish has this membrane but it’s much smaller and not visible unless she flares it.

Vertical Stripes

You will find vertical stripes near the belly when the female betta fish is sexually mature and ready to lay eggs. It is an indication that it’s ready to be paired.

The male betta fish usually creates bubble nests or flares lavishly to show it’s ready to mate.

Can Male And Female Bettas Stay Together In A Tank?

No, keeping male and female betta fish together is not a good idea except when they are mating. The aggressive temperament of the Siamese fighting fish does not allow them to co-exist.

Can Male And Female Bettas Stay Together In A Tank

Female fish can still live, but the male betta fish cannot withstand another betta fish.

But if you are still determined to keep the male and female betta fish together, you should take some precautions to keep them healthy.

You can insert transparent dividers so that they can see each other but can’t attack. After observing their activities for a while, you can decide when to introduce them.

Precautions to take if male betta fish and female betta fish are kept together

Are you a happy betta fish owner and want to create a community in your aquarium? Or are you excited to breed your bettas to add more colors to your aquatic zone?

Be sure to know all the dos and don’ts before putting a male and female betta in a common tank.

Size of the tank

The most important thing while housing both sexes together is a huge fish tank. The bigger the area for them to move, the less territorial they would be. The aquarium decorations will also help in camouflaging during fights.


Before you abruptly put a female betta in a male betta’s company, introduce the two bettas gradually such that they get accustomed to each other. They should not feel threatened by each other’s presence or they will attack and kill.

Juvenile fish

If you want to keep the male and female betta together, keep in mind that the fish should be young. There are chances that the juvenile fish will be less violent toward one another.

On the other hand, the adult fish will not make efforts to interact but instead will project its dominance over others. The betta Splenden will eventually chase, snip, and kill the other.


Now that you are ready to bring male and female bettas together, remember to be well-equipped if the idea works differently than planned.

Prepare another tank beforehand so you can separate the male from the female betta fish if they end up attacking and not co-living peacefully.

Which Fish Is A Better Pet?

Are you still thinking about bringing a male or a female betta home? Which one will turn out to be the better pet?

The decision to own a male or female betta fish is subjective. Read further about how you can decide which one to welcome.


If energetic and moving fins excite you, you should go with a female betta fish, as they are more playful than male bettas. Swirls up and down in the water by the female betta will lift your mood in moments.


If bright colors, dramatic longer fins, and a gaudy aesthetic is your thing, you should pick a male betta as your new friend. They own all the beauty to mesmerize you with it.

The female betta fish are less flashy.


Male bettas are better if you seek emotional companionship from your betta fish. The males of this species are emotional and tend to get excited when they see their owner. They demand attention as they spend their day alone.

The girls are free-willed and play around all day.
