Lili fish is tropical fish, and its origin is in the northeast of India, with warm temperature and tropical region. The alias of Lili fish is called walnut fish, dense perch and small Lili fish. They are small freshwater fish, and their body length is generally between 5-6 cm in adulthood. Their body shape is oval, flat, and their heads and eyes are relatively large. The male fish of Lili fish has three colors: red, orange and blue, which look very bright and have stronger ornamental value than the female fish.

As mentioned above, Lili fish is a tropical fish and likes a higher water temperature. However, they have a wide range of temperatures and can grow in water temperatures between 21 and 30 ℃, but the most suitable temperature for their growth is between 23 and 26 ℃. Because the water temperature is too low, their growth state and speed will deteriorate, and over time, their physique and life will also be affected.

Lili fish does not require high water quality. As long as the water quality for feeding them is clean and refreshing, they can grow well. They like clear, clean old water, and breeders need to install a filter to slow down the deterioration of water quality. If conditions permit, it is best to plant some aquatic plants in the fish tank. Because they are less daring, planting aquatic plants can enhance their sense of security.
