Apart from the aspect of nature, there are ways to distinguish male and female Betta fish. Starting from the pattern on the scales, body shape, fin shape, and so on. Like fish species in general, betta fish are included in the group of vertebrates or vertebrates. This fish was first discovered in the freshwater region of Southeast Asia.

Betta fish can also be called tough fish, because they can live on thin oxygen. This is because the hickey has the shape of a maze-like twisted gills.

This is what makes Betta fish last longer than other fish when they are not in the water, as long as the surrounding temperature is humid.

Even so, fish that are included in this phylum chordata will be more comfortable in fresh water with a temperature of 76-82 degrees Fahrenheit. Such water conditions are also said to be good for breeding grounds.To find out how to distinguish the sex of Betta fish, here are the reviews:

1. Color

Male betta fish usually have brighter colors than females. Usually female betta fish are dull in color and tend to be dark, especially on their body parts.

2. Vertical Lines on the Body of a

female Betta fish on her body will appear vertical patterns when it is ready to mate while the male does not. Usually female bettas who are ready to mate are 3-4 months old.

3. Body Shape

In general, female Bettas are short in shape, while males are long. The sides of the body of the male are longer from the tip of the mouth to the tail.

4. Fins

Male Bettas have much longer fins, sometimes three to four times the length of the female Bettas' fins. In most varieties, females have short tail fins and males have longer fins. In addition, the male's pelvic fins will be longer and thicker than the female's.

5. Egg spots

This is the easiest way to distinguish between female and Betta fish. It is clear and definite that only female Bettas have egg spots. Usually located between their pelvic and anal fins.

This is actually the ovipositor --the place where the egg exits after the male betta has fertilized it. Usually these egg spots will be detected when the hickey is 3 months old and above.

6. Beard Betta

Betta has a membrane under the gill plate covering which is called the opercular membrane. This membrane appears like a beard and appears when the fish spreads its gills.

Males usually have much larger beards than females, so large that they are often seen even when the male betta has not developed his gills.


Male bettais known as fighting fish not without reason. He is very violent and aggressive with other males. Therefore, it is advisable not to keep two males in the same place.

It is also advisable not to combine male and female Bettas in one tank except when mating.

8. Aggressiveness

If a male betta is very likely to attack a female, then the female will almost never attack the male. Even so, female Bettas still have aggressiveness when they meet one sex with her.

However, the aggressiveness between female bettas is not as violent as that between male bettas. Therefore, if you want to place the female betta in one aquarium, it is better to prepare hiding houses for each of them.

9. Bubbles

The easiest way to distinguish male and female betta fish is from this one thing. Because only males make bubbles.

Betta fish make bubbles before mating with females. Has a function to shelter the eggs that the female has released after they mate.
