Clownfish is marine fish. This fish originally lived in warmer waters in the Indian Ocean and Pacific Ocean, including the Red Sea and the Great Barrier Reef, with latitudes ranging from 25 degrees north latitude to 35 degrees south latitude. Because clownfish are distributed in low latitudes, they also belong to tropical fish. Therefore, this kind of fish has high requirements on water temperature, so pay attention to control the water temperature when feeding, and avoid the water temperature below 18 ℃ as much as possible.

There are many kinds of clownfish, and different species of clownfish are distributed in different areas. Some clownfish mainly live in shallow lagoons or coral reefs at the bottom of shallow seas, the junction of India and the Pacific Ocean, the Red Sea, southern Japan, Australia and Sydney.

Because clownfish are tropical fish, it is necessary to control the water temperature when feeding, and the most suitable water temperature for their life is about 26-27 ℃. If the water temperature is relatively low, it may affect their normal life, and they will become unwilling to eat, drink and move. When raising them, it is best to arrange some heating devices in the cylinder, such as heating rods.

Generally, the water can be changed once every two weeks. The water must be sea salt water with a specific gravity of 1.022-1.023, a PH value of 8.0-8.5 and a hardness of 7-9dh. Feed them regularly and quantitatively, and don't feed too much food at one time. The tank for raising this kind of fish is best equipped with egg points, wave making, heating rods, seawater tank lamps, salinity hydrometers and other tools.
