On the mixed culture of clown fish
Clown fish belong to the parsley family, and their personalities are grumpy, especially they are very hostile to the same kind of fish in the new lower tank. There is no problem with mixed culture, but there must be the following conditions: 1. Several fish should be put into the tank at the same time, the time interval should be shortened as much as possible, and the small fish should be put down first and then the big fish should be put down. two。 There are more sea anemones (carpets) in the tank, and three kinds of fish need at least three sea anemones (carpets). 3. The cylinder block should be large enough and the sea anemone (carpet) should be evenly dispersed. The above three rules just try to avoid the fight between them, but they can't solve the problem completely. The healthy and harmonious coexistence of fish still needs your careful care.

Pond fish "raising in winter" has many advantages.
Guangdong Province is located in the tropics and subtropics, and is rich in water and heat resources. in Guangzhou, the annual average temperature is more than 23 ℃, and the coldest January average temperature is still about 13 ℃. This natural advantage is very beneficial to catch pond fish "raising in winter". Practice in various places has proved that "winter culture" of pond fish has many advantages: first, the cold water temperature is low, the organic matter and fertilizer in the fish pond decompose slowly, the pond water is fresh and oxygen is sufficient, which is conducive to the rapid growth of pond fish; second, because of the cold weather, the bacteria and parasites in the pond are not easy to reproduce and grow, and the pond fish
