do tropical fish need light

Aquarium fish don’t need light and it’s best to turn it off during the night. Leaving the light on can cause stress to fish because they need a period of darkness to sleep. Too much light will cause your tank to look dirty. Do not leave your lights on in your aquarium, that’s the short answer. The first thing is to make sure that the lights are turned off when you are not using them.

If you do this, you will not be able to see what is going on inside the tank. You will also need to turn off the aquarium lights when not in use. It is also a good idea to use a dimmer switch on your light switch. This will reduce the amount of light that reaches the fish and will make it easier for them to adjust to the darkness.

Is it OK to keep fish in the dark?

All fish need periods of darkness, and turning the lights off at night will help mimic the natural cycle of night and day.

How much light does a tropical fish tank need?

In general, most aquariums require eight to 12 hours of light each day (10 hours is a good starting point), with a minimum of two hours in the dark. Lighting is the most important factor in keeping your fish healthy and happy, but it’s not the only one.

You’ll also want to keep your tank clean and well-maintained, with plenty of hiding places and hiding spots to hide in when you’re not around. If you don’t have a hiding place or hiding spot, you’ll need to find a way to get around the tank without disturbing the fish.

This can be done by hiding in a corner of the aquarium, or you can hide under a rock or piece of driftwood. Some fish will be more sensitive to light than others, so you may have to experiment with different types of lighting before you find the one that works best for you.

How long should tropical fish tank light be on?

For freshwater planted tanks, around 10 hours of light per day is recommended, and for saltwater tanks, around 12 hours of light per day is ideal. If you want to keep your tank dark all the time, you will need to use a fluorescent light. Fluorescent lights are much more efficient than incandescent or halogen lights, but they are not as bright as fluorescent lights.

They are also more expensive, so if you are looking to save money, it is a good idea to invest in a high-efficiency fluorescents instead of a cheap fluorescent. If you don’t have a lot of room in your aquarium to grow plants, then you should consider using aquarium plants instead. Aquarium plants are a great way to add a little bit of color to an otherwise dark tank.

You can also use them as a way of adding some light to a tank that would otherwise be completely dark. For example, if your water is very dark and you only have room for one or two fish, a few plants can give you a nice change of scenery.

Are aquarium lights necessary?

Unlike plants, fish do not have a biological need for light, so they require less. I don’t know how long my aquarium lights should stay on. 10 to 12 hours a day is a good rule of thumb to give animals and plants the lighting they need.

However, keep in mind that the longer you keep your aquarium light on, the more likely it is that your fish will become ill. The amount of light you need depends on the species of fish you are keeping and the type of lighting you use.

For example, if you want to keep a bluegill, you will need at least 1000 lumens per gallon of water. If you’re keeping a tropical fish like anemones, then you may need up to 2000 Lumens. You will also need to consider the size of your tank.

Smaller tanks will require more light than larger tanks, but you should still be able to provide enough light for the fish to stay healthy.

Do fish like light in their tank?

It’s a good idea to start with a light period of 12-16 hours and a dark period of 12-8 hours for indoor tanks that don’t have corals. Not all fish will like the same light and dark periods. A slow increase in light is better for fish than a rapid decrease.

If you have a tank with a lot of fish, you may want to increase the amount of light for a few days to see if it helps. If it does not help, then you will need to decrease the light. You can do this by changing the tank lights or by switching to a different type of lighting.

Can fish in an aquarium see you?

In addition to being able to see their prey and recognize their owners, fish can also see a range of colors since they have a color sense in their eyes. Many species of fish can also see ultraviolet (UV) light, which is invisible to the human eye, but can be seen by fish.

Fish also have a sense of smell. They can detect chemicals in the water, such as ammonia, nitrite, and nitrate, as well as the presence of other fish and other animals. Some species can even smell their own urine.
