1, appearance difference: forktail betta body size and body color betta sex. Generally speaking, the male fish should be more colorful and larger. The females are a bit duller in color and smaller.
2, belly difference: male channel tail betta body is relatively symmetrical, the abdomen is not obvious bulge, relatively flat. The female channel tail fighting fish is relatively large, the abdomen is relatively large, in the breeding period will be bulging, very obvious.
3. Difference of caudal fin: Generally speaking, the caudal fin of male fish with a length of more than 3cm is relatively slender, and the wiredrawing is relatively long. The female fish with a length of more than 3 cm has a shorter tail and a shorter wiredrawing, and some even have no wiredrawing. This is generally used as a supporting evidence, because there are individual male fighting fish growing up after the wire is not very obvious.
4. Habit difference: During the breeding season, the male fish will begin to spit bubbles after oestrus. Most females do not have the habit of spitting bubbles. Therefore, if oestrus, spit bubbles are mostly male fish, and not spit bubbles is the female fish.
forktail betta male and female can be raised together. However, when breeding, a large enough tank should be used. If the tank is not big enough, they may fight for territory. When the fish grows to more than 3cm, it is recommended to fish out the male fish and raise them separately. This can make them look better. If you want to breed in groups, you must control the proportion of male and female, male fish should not be too much, otherwise they will fight.
