In general, males are flashy and have many different colors, with blue, red, green, and black patterns on a gray, yellow, and white background, while females have more monotonous colors than males. There is also a lot of variation in the tail shape of males.
In the process of evolution, the male's pelvic fin was transformed into a mating device, which allows sperm to enter the female's body. Sperm are stored in the female's body and are fertilized several times. In other words, it can be fertilized multiple times with one mating. It is an ovoviviparous fish and usually gives birth to offspring once a month, with the maximum number of offspring being 150. When the fry come out, they first go down to the bottom and after a while they come up to the surface and swim.
It is a representative tropical oviparous fish species and is widely bred for ornamental purposes. There are varieties with beautiful shapes and colors. They are easy to raise and have strong reproductive capacity, so if you put a male and female together in a tank with abundant aquatic plants, their numbers will naturally increase. They tend to live in the surface layer of the aquarium and do not harm other fish. Their food is worms, etc. Lifespan is 2 to 5 years.
