What Are The Benefits Of A Fish Tank In Your Bedroom?

If you’re still deciding whether you should put a fish tank in your bedroom or not, here are some of the biggest benefits you can expect from doing so!


One of the biggest benefits that comes from putting a fish tank in your bedroom is relaxation! In fact, it’s been proven that tracking fish with your eyes can help reduce anxiety!


As well as relaxation, a fish tank can be a good source of entertainment as well. If you have a lively bunch of fish in your tank, then you can be entertained for a long time. You can even teach some fish to do tricks!

It Can Provide White Noise

If you’re someone that needs white noise to be able to sleep properly, then having a fish tank in your room will be a great way of providing this! Not only will the sound of the filter provide white noise for you, but hearing the water trickling can also soothe you too!

It Can Help With Sleep

And lastly, you may know that watching TV or being on your phone before bed can cause sleep problems and affect your sleep. By looking at your fish tank before bed, it can help you fall asleep quicker and help you feel more rested in the morning!

Why Are Fish Tanks Bad In Bedrooms?

While there are plenty of good reasons to keep a fish tank in your bedroom, there are also some reasons that you may want to avoid keeping them in your bedroom too!

It Could Be Too Loud

First of all, it could end up being too loud. If you pick the wrong filter, then it may end up keeping you awake all night. As well as this, the sound of splashing water could also keep you up.

Fortunately, if your fish tank is too loud at night, there are a few things you can do:

  • Adjust the filter nozzle, so there’s no drop from the filter into the water.
  • Adjust the level of the water.
  • Find a filter that is quieter.
  • Keep the tank away from your bed.

It Could Be Too Bright

As well as being loud, it may also end up being too bright as well. Especially if you don’t have a blue light setting but only a white light setting.

Fortunately, if the tank is too bright, it’s a much easier fix than if it’s too loud. When your light is too bright, you should try the following:

  • Use an automatic timer that turns the light off when you go to bed, and back on when you wake up.
  • Get a remote control light, so you can turn it off from your bed.

Remember, a tank light shouldn’t be on all the time anyway, so turning it off is beneficial for your fish too!

An Unpleasant Odor

Sometimes, the tank can also end up smelling a bit. Especially if it hasn’t been changed in a while as well. Decomposing food, fish and plant waste, dead fish, and old water can all be reasons for the tank to smell. 

However, again, to fix these issues isn’t overly difficult. You just need to make sure you do the following:

  • Make sure you change the water frequently.
  • Remove any dead fish and uneaten food in the tank.
  • Add a carbon filter which will remove any of the smells (however, it will need changing every couple of weeks).
  • Make sure you’re keeping the tank clean as well. 

Too Much Moisture In The Room

If you have a large fish tank in a small room, and there’s no lid on it, then you may end up with a room that has far too much moisture in it. In fact, depending on the heat of the room, a lot of water can evaporate from your tank in one day.

If you’re worried about your fish tank adding too much moisture to your room, then here are a few things you can do to stop that from happening!

  • Keep a lid on your fish tank to drastically reduce the amount of water leaving the tank. 
  • Make sure your room is well-ventilated.
  • Use a dehumidifier.

Where Should You Put A Fish Tank In Your Room?

When you’re deciding where to place a fish tank in your room, there are a few things you should be aware of. So take the following into consideration:

In A Quiet Area

First of all, you should make sure you’re placing your tank in a quiet area. Noise entering your fish tank is likely going to stress your fish out, so a quiet area of your room will help make them feel safe.

Away From Sunlight

You should also make sure that you’re keeping your fish tank away from sunlight as well. When your aquarium is in direct sunlight the amount of algae that is likely to bloom will increase dramatically.

As well as this, too much sunlight may also heat the tank up and make the temperature unstable, as well as increasing the rate of evaporation.

Away From Drafts

You should also make sure that you’re keeping your fish tank away from drafts as well. Just like the sun can heat your tank up too much, a drafty area of your home can cause the temperature of the tank to drop dramatically. 

Away From Your Bed

And lastly, you should try to keep the fish tank away from your bed as well. When the fish tank is close to your bed it will be louder and brighter, which could end up affecting your sleep.

Can A Fish Tank In Your Bedroom Make You Sick?

It’s extremely unlikely that a fish tank in your bedroom is going to make you sick. However, if your room did become too moist because of evaporation, it could result in mold starting to grow, which is particularly harmful to people who are allergic or have asthma etc.

Is A Fish Tank In Your Bedroom Good For Feng Shui?

Unfortunately, if you’re interested in feng shui, you’ll be saddened to know that a fish tank in your bedroom is actually a bad idea. Bedrooms are a place for peace, and relaxation, whereas fish tanks are supposed to bring the opposite of that energy.

What Are The Quietest Filters To Use In Your Bedroom?

If you’re going to add a fish tank to your room, then you’ll need a filter that is as quiet as possible. Some great filters to choose from include:

  • Aqueon QuietFlow LED PRO Aquarium Power Filter 
  • Tetra Whisper IQ Power Filter with Stay Clean Technology 
  • MarineLand Penguin 200 Power Filter 
  • Penn-Plax Cascade 300 Power Filter 

You should pick which filter you choose based on the size of your tank.

Best Aquarium For Bedrooms

If you’re going to add an aquarium to your bedroom, then you’re spoiled for choice! However, a tank up to 20 gallons in size is probably your best choice. 

Because of this any Fluval, Aqueon, or Tetra aquarium will be a great choice for you!


As you can see, keeping an aquarium in your bedroom isn’t going to be a problem, just make sure it’s not too loud and that the light isn’t too bright. If you do this, and keep your room well ventilated, then a fish tank will provide a whole host of benefits for you!
