Before the lights in the tank turned off, my jawfish put themselves to sleep. They have been asleep for a couple of hours by the time I get to bed.

How many hours of darkness do fish need?
Fish need about 12 hours of light and 12 hours of darkness. In fact, it is best to leave the aquarium lights on 24 hours a day, 7 days a week. If you want to keep your fish in the dark all the time, then you need to make sure that they are getting enough light.
If you have a fish tank that is too dark, you will not be able to see what is going on in your tank. This is especially true if you are keeping fish that are very sensitive to light, such as cichlids, which are often kept in dark tanks.
It is also not a good idea to have too much light in a dark tank, as this will make it difficult for the fish to regulate their body temperature and will also make them more susceptible to disease. A good rule of thumb is that a tank should have at least 10% more light than it needs to be in order to maintain a healthy fish population.
However, this does not mean that the tank must be completely dark at all times, just that it should be brighter than the ambient light level.
Are fish OK in total darkness?
Aquarium fish can rest at anytime, not only at night when it’s dark. The other reason fish need a period of darkness is to mimic the cycle of the sun setting and setting again. In the aquarium, fish should be kept in groups of two or three.
They should not be allowed to interact with each other. If they are kept together, they will be more likely to get sick and die. It is better to keep the fish in separate tanks.
Do LED lights affect fish?
Plants are more dependent on light than fish. In general, aquarium owners can use incandescent, fluorescent, or LED lights for fish but should be aware of the heat generated by these lights and the potential for damage to the fish’s eyes. Aquarium lighting is important for the health and well-being of your fish.
It is also important to keep in mind that the amount of light your aquarium receives will depend on several factors, including the type of fish you have, the size of aquarium, and whether or not you are using an aquarium heater.
Do fish like light in their tank?
Energy and oxygen are provided by lighting to ensure the well-being of your pets, as well as the growth of plants and organisms. Light is essential for the healthy growth for fish, plants, corals, algae, and other aquatic life. In addition to providing energy, light also plays an important role in the growth of plants. Plants need light to grow and photosynthesis to take place.
When plants are exposed to too much light, they can become stunted and die. Too little light can also cause plants to wilt, which can lead to the loss of valuable nutrients from the soil. This is why it is so important to provide adequate lighting for your aquarium.
Should I turn fish light off at night?
The short answer is No – you SHOULD NOT leave the aquarium light on overnight. Light and darkness are needed by fish to survive. The fish need darkness to rest. They need a dark environment to get a good night’s sleep because they don’t have eyelids. The long answer, however, is a bit more complicated.
One of the most common reasons is to keep your fish safe from predators. If you leave them alone in the dark, they are more likely to be attacked by other fish. Another common reason is that you want your tank to look as natural as possible.
You don’t want the lights to interfere with the natural coloration of your fishes. Finally, if you have a large aquarium, you may be able to afford the extra cost of keeping your lights off for a longer period of time than you would with a smaller aquarium.
Can fish sleep in blue light?
No, you should not keep a blue light or any other colored light on in your fish tank through the night. If you don’t have nocturnal fish, they rely on light cycles to sleep. Leaving a light on at night will cause sleep deprivation for fish. If you want to keep blue lights on all the time, it is best to use a fluorescent light.
Fluorescent lights are more energy efficient than incandescent lights, and they do not emit any harmful UV rays. They are also less expensive than other types of lights. However, fluorescent lights do emit some harmful light, so they are not recommended for use in fish tanks with fish that are sensitive to the harmful effects of UV radiation.
