The betta is a relatively small tropical fish, generally able to grow to about 5 cm. However, there are many varieties of it, and some varieties can naturally grow bigger. Under suitable breeding conditions, they can grow up to 12 cm, or even 15 cm long. How big a betta can grow depends on its sex. Usually, the male betta is smaller than the female betta, but the male betta has larger fins than the female betta.
The betta usually can live for 2-5 years. How many years it can live has a lot to do with the breeding environment. If the breeding conditions are good, it can live for 5-6 years. The current record is eight years. If the breeding environment is poor, it can only live for 2-3 years. The use of 25-28 C water in aquaculture can make betta grow better and live longer.
The betta can reproduce when it is 4-8 months after birth, that is, when it grows to 5-6cm. However, early reproduction is not good for the fish itself. Therefore, it is recommended to wait for the fish to be a little bigger before breeding. Generally, female fish can reproduce as long as they have eggs, while male fish can only reproduce when they spit bubbles. However, too frequent breeding is also not good for fish, so it is generally recommended not to breed more than four times a year. Do not breed more than once a month.
