Tropical fish are born in tropical waters. Tropical fish are divided into freshwater tropical fish and seawater tropical fish. However, in the near tropical zone and the north and south temperate waters bordering it, ornamental fish species are also classified as tropical fish, so their distribution also includes some subtropical areas.
Tropical fish is actually a fish lover. In order to distinguish it from other ornamental fish, these ornamental fish endemic to tropical and subtropical areas are collectively called tropical fish. They live in fresh water areas such as rivers, streams and lakes.
The hometown of tropical fish is mainly in Southeast Asia, Central America, South America and Africa. Among them, the Amazon river system in South America produces the most kinds and the most beautiful forms, such as the queen jujube fairy fish in tropical fish, which was born there. There are many kinds of tropical fish in Malaysia, Indonesia, Sri Lanka, Thailand, Myanmar and other countries.
In the south of Guangdong, Yunnan and other provinces in China, there are also beautiful ornamental fish, such as Parthenocissus tricuspidata, white cloud snakehead and blue star fish in Xishuangbanna.

Necessary equipment for raising tropical fish
1, fish tank: it is the place where tropical fish grow and move. Tropical fish must be raised in a slightly larger rectangular glass fish tank.
2. Suction tube: used to suck out the dirt at the bottom of the fish tank when changing water, which is formed by connecting a soft rubber tube with a glass tube. The length depends on the height of the fish tank. Generally take one meter two to one meter five.
3. Thermometer: used to measure and adjust the water temperature of the fish tank.
4. Fishing nets: used to catch and transfer tropical fish.
5, glass lamp tube: put the light bulb into the glass lamp tube and sink into the fish tank for heating and lighting. The glass lamp barrel mouth must be higher than the water surface 100MM to prevent fish from jumping in.
6, electric heating tube: used to increase the temperature in the fish tank in winter.
7. Air pump: discharge carbon dioxide from the fish tank and increase the oxygen content in the water.
8. Filter: Filter out the dirt in the fish tank, keep the water clean, and play a dual role in increasing oxygen and purifying the water.
9. Thermostat: It is used to automatically control the temperature in the fish tank and can keep the temperature constant for a long time.
10, food bucket: prevent fish food from floating on the water surface, which is beneficial to fish predation. It can also prevent fish food from falling into the bottom of the water and drilling into aquatic plants, blackening aquatic plants and sand and destroying water quality.
1 1. Detergent solution: made of plastic plate. Used to scrape the dust and oil on the water surface of fish tank.
