1. The environment is stable: A mermaid likes a higher water temperature, and they are tropical fish, which are sensitive to the change of water temperature. In artificial breeding, it is necessary to use heating rods to keep the water temperature in a stable range. The fluctuation of water quality also has certain influence on them, so it is best for breeders to change water regularly and control the amount of water to avoid the great influence of water quality fluctuation on them.

2. Regular disinfection: Mermaid has poor resistance to viruses, so it is best for breeders to sterilize fish tanks regularly to avoid their infection. As long as there are fewer bacteria in fish tanks, their chances of getting sick will also decrease.

1. Choice of tank: One-eyebrow mermaid does not require very high space, but they like to grow in the environment with dense aquatic plants. Breeders can plant some aquatic plants in the fish tank where they grow or put them directly into the grass tank for breeding.

2. Feeding: One eyebrow mermaid is a small fish, which doesn't eat much and doesn't have high food requirements. Breeders can choose to feed animal feed and plant feed together, so as to ensure their adequate and balanced nutrition.

3. Environment: The mermaid is a tropical fish, which likes a higher water temperature. The breeder can keep the water temperature between 20-26 ℃. They like clean and refreshing water quality, and it is best for breeders to change water once every three days, and the amount of water changed each time should be controlled at a quarter of the total amount of water.
