Canlan betta

Common name aliases: colorful fighting fish, fighting fish and colorful finch fish.

Origin (country) Thailand, Malaysia, Singapore and other countries.

Body shape and habits fish can reach 8 cm in length. Thai betta likes to live in water of 22~24 degrees, but not lower than 20 degrees. Although the acidity, alkalinity and hardness of water are not important. I like eating old people. Betta in Thailand is famous for its aggressiveness. When two males meet, they will definitely fight. When fighting, they will open their cheeks and shake their fins. Therefore, in aquaculture, 1 tank can not raise more than two adult males, but it does not compete with other tropical fish. Female bettas don't fight each other. You can keep a jar with me. Price: 2.5 ~ one in 20 yuan.

Reproductive characteristics:

Reproduction is easy. Put the selected parent fish in an aquarium with good water temperature and quality, and let them breed by themselves. In the breeding process, the male fish blows air first and spits mucus on the water surface, forming small bubbles, and countless small bubbles stick together to form floating nests with raised or slightly flat surfaces. After the male fish built the nest, he immediately proposed to the female fish. The beautiful male fish has been swimming around the female fish, trying to open his beautiful fins, his mouth is wide open, his gill membrane is prominent, and bright red gills can always be seen below. In the process of courtship, the color of the male fish becomes very bright, the body and fins appear rainbow color, and the body trembles with extreme excitement. Sometimes the female fish can't react to this excitement, and the male fish will become angry and run after it until he is forced to jump out of the water and escape.

If there is a fight between men and women, the male fish should be fished out immediately and another male fish should be used as the father. After the courtship, the female fish accepted the proposal of the male fish. She approached the male fish first, and then suddenly lay on her back. The male fish clings to the female fish, then the female fish turns up and down, the male fish is under the female fish, and the female fish begins to ovulate. After the eggs are discharged, the females hold them for a while. At this time, the male fish has dispersed the semen in the water, and the female fish relies on the activities of the head and mouth to make the eggs stay in the water with semen for one minute to ensure fertilization. Because the fish eggs are heavier than water, when the fish eggs sink, the male fish waiting below immediately catches them with his mouth, coats them with mucus, swims up and sticks to the bottom of the floating nest. The female fish only lays 3 ~ 7 eggs at a time, and this action is repeated until 150 ~ 200 eggs are laid. The male fish is responsible for taking care of the eggs and preventing the female fish from swallowing them. After hatching, the larvae temporarily attach to the nests. If any larva sinks, the male will drag it back to the floating nest. This kind of protection is effective until the larvae can swim and eat by themselves and leave the floating nest naturally.

The gonads of Thai betta fish mature from 4 to 8 months old. Female fish are smaller than male fish, with smaller fins and worse color. Choose more than 6 cm as parent fish. After the male and female fish are combined according to the ratio of 1: 1, the male fish spits out to nest and the female fish enters the brooding area. Finally, the male fish wraps the female fish with his body many times, and then lays eggs and ejaculates. This process lasted almost two days. During the incubation period of fertilized eggs, the female fish is fished out, leaving the male fish to keep the nest and protect the young. Two days later, the fry hatch and the male fish are fished out. During 1 year, it breeds many times, and lays dozens to hundreds of eggs at 1 time. The water temperature of aquaculture is 2 degrees higher than usual, reaching 26~27 degrees. The water quality is weakly acidic and neutral, and the hardness is about 8 degrees.
