There is a kind of fish, tropical fish, which is bought from the store and needs to be hatched. The color is very bright. What's its name? To attach

I bought a magic fish, but it's actually a giant fish. The salamander family is generally oviparous (except giant salamander) and has bright body color. Eggs can be preserved in muddy soil in a dry environment and can hatch into fish after adding water.

Native to South America or Africa, it is packaged as a magic fish.

There are specific incubation steps in the manual, and Baidu also introduces them.
