The easiest way to tell the difference between the sexes of betta fish is by the size of their fins. The larger one is male and the smaller one is female. However, this is limited to species with large fins such as traditional bettas and show bettas.
In the case of other varieties, individuals that have grown to a certain extentLook at the abdomen, if you see a white ovipositor, it's a female, if not, it's a male., can be distinguished.
When to breed bettas
Male betta fish build bubble nests above the water surface, and females lay their eggs there. Therefore,If the male starts making bubbles on the water surfaceThis is a sign that the cat is in heat.
It will be okay to move on to breeding. Females have ovaries near the ovipositor, so if the area near the ovipositor in the abdomen is large, it means they have eggs, so try breeding them.

We are both in heat,Once the male has built a 4-5 cm bubble nest, gently introduce the female into the breeding tank.
The female heads to the bubble nest built by the male. At this time, the male attacks the female to lure her to the nest.The female's body will fall apart, but let's keep an eye on her for a while.
The male wraps himself around the female to mate and lay eggs. The fertilized eggs fall to the bottom and the male picks them up and takes them to the bubble nest.
④ Isolation of females
After confirming that the female has spawned, or if she has not mated or spawned within a few days, isolate the female and return her to her original tank. Since the body is injured, infections may occur from there.

Bettas only spawn once50 to 100 pieces, sometimes 200 piecesIt lays eggs. If the breeding tank is too small, it will become overcrowded and it will be difficult for the fry to grow, but if things go well, they will grow to a certain size by 50-70%.
