Kingman arowana is a kind of fish that likes light. The fish tank must be placed in a place where solar energy can shine. There must be at least four hours of light every day. If this requirement can not be met, you can also place a light in the fish tank, but this way is only a temporary measure, it is difficult to achieve the same effect as the sun, long-term lack of light, fish may fade.
Kingman arowana belongs to tropical fish, so there are certain requirements for water temperature, usually the temperature should be maintained between 20-27 ℃. However, it can also tolerate slightly lower temperatures, can still feed in 18 C environment, can live in 14 C waters, but below 11.5 C, the fish will be frozen to death. In addition, it can live in places with low oxygen content, and special structure allows it to breathe at the surface of the water.
The feeding habits of the kingman arowana are relatively miscellaneous. There are many kinds of acceptable food. They prefer aquatic animals, especially live bait. They can be fed to cladocerans, such as red worms. It also eats artificial feed, but usually with live bait feeding, long-term use of a single feed, easy to affect its appetite, leading to it not to eat.
In order to ensure the health of the fish, change the water regularly, according to the temperature and season, the interval of water change is also different. Summer temperature is high, water quality is easy to rot, so water change should be more frequent, and in winter, the temperature decreases, water change time can be extended appropriately. Do not change more than a third of the water at a time, as too much will irritate it.
