I. Do arowana sleep?
Arowana is a popular ornamental fish one. Like most animals, sleep is necessary for dragon fish, and sleep can also help them relieve fatigue. However, as a kind of fish, Arowana is a relatively low-level animal with a relatively small brain capacity. So, although dragon fish need to sleep, they don’t need much time to sleep. Compared with the sleep time of mammals, their sleep time is very small. Moreover, the sleeping state of dragon fish is relatively light, so they are not easy to detect when they are sleeping.
Second, how does Arowana sleep
The sleep state of Arowana is not easy to be detected, Another reason is that they don’t have eyelids like other fish, so they sleep with their eyes open. Generally speaking, they generally do not sleep in brightly lit places, and more often they go to a relatively safe place to stay, such as in the grass or the corner of the fish tank
. At this time, their activity decreases, their swimming becomes sluggish, and they slowly enter a sleep state.
Arowana does not completely suspend activities when sleeping. Even when sleeping, their bodies will wiggle slightly, and their fins and gills will open and close slightly and repeatedly. , but at this time their formation and metabolism will slow down, so as to restore physical strength and relieve fatigue. If you observe carefully, you can also observe the sleeping state of the dragon fish. Generally speaking, when Arowana’s movements become sluggish at night, they are likely to be sleeping.
Third, how long does Arowana sleep for?
Arowana The daily sleep time is not fixed, and the sleep time is not fixed. Generally, as long as the surrounding environment is quiet and dim, the dragon fish will easily go to sleep. Therefore, Arowana may sleep more times a day, and it is difficult to infer their sleep time in a day. But what is certain is that Arowana sleeps longer at night than during the day, and sleeps more soundly. But they don’t sleep longer than mammals, and they don’t need a lot of sleep to be precise.
