The Benefits Of Owning A Fish Tank

1). It reduces stress

We struggle daily to mix work with spending time with our families, paying bills, and so on. By doing so on a daily basis, we become overwhelmed by the many duties that we have to complete, so we need mechanisms to cope with such effort. The real challenge is finding ways to release or reduce the pressure that all this running around provokes. Along with physical exercise, yoga, and meditation, fish tanks are a great way to lower the stress level and reduce overall anxiety. Didn’t you notice that as soon as you get into a calm environment, you become more relaxed? It is scientifically proven that even taking care of a fish tank releases stress because it takes your mind off of any unfinished chore.

2). It improves sleep quality

We seldom take home with us the burden of a hard day and before we know it, while sleeping, racing thoughts cause us insomnia, a condition that we tend to ignore, but that, left untreated, can get pretty serious. An aquarium placed near your bed can help you sleep better. The good energy that a fish tank brings to your room reduces tension and also wards off any negative thought you might have before going to sleep.

3). It maintains good blood pressure and a normal heart rate

In The effects of interacting with fish in aquariums on human health and well-being: A systematic review” written in 2019, studies have shown that the presence of an aquarium in a room can lower a person’s heart rate and blood pressure. When someone admires a fish tank filled only with marine seaweed and rocks, the heart rate may lower by 3%, while if you add fish to the aquarium, the heart rate lowers by 7%, which is quite impressive. This stress reducer is beneficial for those who suffer from cardiac arrest too by consistently lowering their blood pressure.

4). It decreases anxiety

Many doctors, therapists, and dentists have placed an aquarium in their waiting room. It is not set there only for show, but rather for its capacity of calming and soothing physical and psychological pain.

Those who were exposed to an aquarium while standing in the waiting room experimented less pain during the treatment applied by their dentist. Also, they needed a lower dose of tranquilizers after leaving the doctor’s office.

A fish tank is a natural treatment for those suffering from an anxiety disorder. Similar to hypnosis, watching fish swimming in a tank drifts one’s attention from uneasy thoughts, calm their mind, and helps them leave any problem aside, and just be present in that moment.

5). Great therapy for hyperactive children

Specialists say that children suffering from hyperactivity tend to take things easier when watching fish peacefully swimming in an aquarium. Not only it helps them cool down, but it also grants them a night of good night sleep. Hyperactive children might show better results in school as well after constantly being exposed to this type of therapy.

6). It improves productivity

By reducing stress and lowering blood pressure, an aquarium can help you focus better on daily tasks. The aesthetic value of an aquarium enhances your creativity at work and thus improves your productivity.

7). It helps patients with Alzheimer

Studies made on Alzheimer patients have proven that watching an aquarium with lively colored fish has helped them to improve their eating habits and to minimize their disruptive behavior. By relaxing, patients are less prone to physical aggression. Plus, their short-term memory has been improved allowing them to reduce medication.

Why Should You Buy A 120 Gallon Aquarium?

Because a well-endowed aquarium, regardless of the types of fish you plan on accommodating in it, has to be spacious, impressive, easy to see, and admire. From small fish to 18’’ Pleco, or 14’’ Oscar, a gallon of these dimensions meets all the requirements to house small to big fish in optimal conditions.

Speaking of dimensions, the typical proportions of this type of aquarium are 46cm x 152cm x 66cm. They usually come in a rectangular shape, which makes them very stable and safe not only for the fish inside but also for the external environment.

Be mindful of the weight and size of these fish tanks, as they will require more time for maintenance. Certainly, not only the price of the fish tank, but also the maintenance costs are higher, but it is totally worth it. The consequent satisfaction is that a well-groomed fish tank will embellish your living environment.

The Stand – A Must Have When Owning A 120 Gallon Fish Tank

If you plan on buying an aquarium, think of purchasing a stand too. Unless your aquarium is already equipped with one.

You wouldn’t want to place your aquarium directly on the floor or on a table, especially when we’re talking about an aquarium of such dimensions.

A stand is designed to support large tanks and also ensure the safety of the aquariums and of the outside environment.

If you already have a DIY stand at home, then that’s great, you can use that one. If not, do not hesitate to buy one and also think of the spot where you are going to place it, because once you settle the entire kit inside your house, it will be harder for you to move it due to its consistent weight.

Think of investing in a rather sturdy compliant stand for your 120-gallon fish tank. It should typically measure the same size as the tank, maybe a bit taller (about 76 cm).

Types Of Aquariums

Next, we will note the main differences between a sealed and an open-top fish tank.

a). If you decide to go for a sealed aquarium, consider the fact that the plants and fish inside will not be easily accessible. Plus, a sealed fish tank keeps more warmth inside, causing more water to evaporate. Also, your plants won’t be allowed to grow too tall. Another disadvantage would be the unpleasant algae smell that you might feel as soon as you unseal the aquarium. Also, keep in mind that it might be harder for you to install any additional equipment because of the cover.

On the other hand, there will be no ejected water when fish do their jumping. Plus, you won’t find any fish hopped out of the aquarium like you sometimes might when owning an open-top fish tank. With a closed fish tank, you will also spare yourself the dust that penetrates the open-top fish tank.

b). As for the open-top fish tank, it is, first of all, more expensive than the closed one; it also allows plants to grow outside of the aquarium, giving you, the observer, an amazing view; the access to the fish and plants inside the aquarium is easier and faster.

As a side note, we would suggest you buy a quarantine or maternity fish tank. Newer fish should be held in quarantine for a while, under strict surveillance. Thus, you avoid causing any illness to the other fish, in case something is wrong with your new acquisitions.

As for maternity, baby fish might not survive alongside the rest of mature fish, which is why they should be kept in a different tank for a while. So, we would suggest you opt for the ideal 120-gallon fish tank as the main aquarium, then we would recommend you to go for a second one smaller to serve you as a quarantine fish tank, for instance, one of the 40-gallon fish tanks or even a 55-gallon aquarium.

What Does a 120 Gallon Fish Tank Include?

Here is a list of the equipment that a regular freshwater fish tank can include:

  • The fish tank itself
  • The internal or external filter
  • A means of filtration
  • Lights (we recommend LED)
  • The water or substrate heater
  • The chiller (if necessary, for warmer areas)
  • A water pump (usually included with the filters)
  • An air pump
  • The UV filter
  • Water tests
  • A CO2 system (for heavily planted tanks)

Besides the stand, we would recommend you to add to your maintenance kit the following accessories: a well-calibrated digital thermometer, a fishnet, a window cleaner, an UPS, a surface skimmer, a gravel cleaner, adjustable outlets, a food dispenser.

Final Words

As you can see, picking the right 120-gallon aquarium is not easy, but hopefully, this guide has made things clearer for you and now you can decide upon your best option. Remember to properly equip and maintain your fish tank and you will enjoy a spectacular view at home or at work every single day.
