How big is ? A 100w heating rod is suitable for a 40cm long fish tank. Usually, the power of the heating rod should match the size of the fish tank. If the fish tank holds several liters of water, it should be equipped with 1.5-2 times the power of the heating rod. For example, if the volume of a 60 cm cylinder is less than 100 liters, the power of the heating rod will be between 150 and 200 w. If it is an 80cm long fish tank with a volume of about 160 liters, it needs to be equipped with a 240-320 w heating rod.
1. Angelfish: Angelfish, also known as swallow fish or angel fish, is one of the ornamental fish of the genus Angelfish in the family Cichlidae, native to South America. The body length of this kind of fish is between 12-15 centimeters, and its character is very quiet, so it is easy to carry out polyculture. As a tropical fish, it must control the water temperature and keep the temperature between 26 and 32 degrees Celsius.
2. Lucky fish: Lucky fish, also known as warship, is a large ornamental fish of the gourami family. Its length is about 20-70 cm. It is not strict with water quality, but also has a strong ability to tolerate hypoxia, so it is relatively easy to raise. Because it lives in the tropics, the water temperature is generally around 22-32 degrees Celsius.
3. Arowana: Arowana is a large ornamental fish, with a body length of about 50-65 cm and a life span of up to several decades. Because of its ferocious temperament, Arowana feeds mostly on fish and shrimp, so it seldom carries out polyculture. This kind of fish also has a higher requirement for temperature, if the heating rod is not used to control the temperature, the appetite will be greatly affected.
