Lili fish are oviparous fish, which are fertilized and developed in vitro. When they breed, the female fish lays eggs first, and then the male fish inseminate. After successful fertilization, fish eggs will hatch into small fish. They are different from ordinary oviparous fish in that the male fish of Lili fish has the habit of protecting their eggs. After fertilization, they will always guard around the eggs until the eggs hatch into small fish. Therefore, when Lili fish is produced, the breeder only needs to fish out the female fish. Male fish can be placed in a fish tank to protect their eggs. After the eggs hatch successfully, the male fish can be fished out.

1. Pairing: Lili fish is an oviparous fish. When reproducing, male fish will look for mature female fish by themselves. When the two fish are successfully paired, the breeder can prepare separate breeding tanks for them.

2, nesting: Lili fish males spit out bubbles one by one with mucus in their mouths before production, which is called bubble nesting. When they get better and better, the female fish begins to lay eggs, and after the female fish lays eggs, the male fish will be inseminated forward. After successful insemination, fish eggs will become fertilized eggs. When the eggs are fertilized successfully, the male fish will transfer the eggs to the built bubble nest.

3. Hatching: The male fish will always guard the fertilized eggs, and will constantly flap their fins to ensure that they have enough oxygen. If the bubble nest is broken, they will come forward to repair it until the eggs hatch small fish.
