Benefits of Having a Fish Aquarium

  • Fish tanks have a soothing effect that contributes to peace and tranquility at home. When aquarium inhabitants move in your tank, they produce a hypnotic affect.
  • It relieves stress and improves productivity. When you watch the pet fish swimming gracefully inside your fish tank, it takes your mind on a comforting slow ride of imagination and stress-free relaxation [1].
  • They are not noisy compared to other pets such as dogs and cats. Neighbors will not complain about a noisy pet.
  • It provides children with the opportunity to learn how to be responsible. When they feed the scaly sidekicks and clean the fish tank, it encourages a high sense of responsibility.
  • It can reduce your blood pressure. This effect is achieved with the serenity and peace that the gliding fish give [2].

Important Features to Consider

It takes a lot of effort to find the perfect aquarium and to make your pets feel comfortable in their “nest.” If you have made up your mind to keep fish as pets, you need to think of things that will make them feel comfortable. In part, this includes knowing what to consider when selecting an aquarium. You also want to make sure your fish tank will bring a splash of beauty to your space. To make this happen, here are a few important features you should consider.

  • Accessories included. If you are a newbie and searching for an easy way to break into the aquarium industry, then buying a fish tank that has everything you need at your fingertips (for example, fish food, a filter, and a heater) is a great idea. Look for an all-in-one kit, rather than a stand-alone aquarium.
  • Size. You want to be sure you buy an aquarium suitable for your fish family. Large fish tanks are generally more challenging, but a too-small will not be healthy for your pet fish. Check the dimensions to make sure your aquarium fits in the allocated space.
  • Cost and fish type. Although the initial cost is usually high, the subsequent maintenance costs can be low depending on what type you buy. The same is true for various species. Some of them are a bit pricey, while others are budget-friendly. Firstly, determine the type of fish you want to keep before starting to think of an aquarium. And even if you choose a cheaper option, make sure it has the necessary features required to ensure the safety of your fish.

🐟 What size Fish Tank should I get?

“There is no single best-sized aquarium,” says Robert Woods, a third-generation fish keeper, member of the Association of Zoos and Aquariums, the Marine Aquarium Societies of North America and the Nature Conservancy.

However, there are certain rules that you should follow:

  • The bigger the fish tank, the easier it is to maintain.
  • Always make sure to purchase the fish tank larger than necessary so your fish can thrive.
  • If you cannot get an aquarium of a suitable size, you should buy a different type of fish.
  • The bigger the aquarium, the happier your pet fish will be[3] .

🐠 How to set up a Fish Tank?

1. Do not move a full aquarium. Your hands should be dry when you lift the fish tank. Do not lift the aquarium by holding the frame or edges. Make sure to grab and carry the aquarium from below; there should be a support on the bottom.

2. Clean the fish tank inside and out using a drenched fabric. Be sure to use warm water without chemical-based cleaning agents, detergents, or soap.

3. When you decide where to put the aquarium, select an area that can support its weight. Keep in mind that an aquarium filled with gravel and water weighs between 10 and 12 pounds per gallon. Therefore, you need to place it on a balanced and flat surface and make sure there is an electrical outlet nearby.

4. Before you put gravel inside the fish tank, you must clean it thoroughly.

5. Fill the tank with water until it is one-third full. It is highly recommended to pour the water moderately to make sure the decoration won’t be displaced. Then you can add plants before you fill up the aquarium. It is also significant to treat the water with a dechlorinating agent before adding it to the aquarium.

6. Install filters, lighting, pump, and a heater. Most aquariums come with technical equipment installation instructions. Follow the instructions carefully to get the most benefit. Before installation, ensure that the filters and heater are cleaned thoroughly.

7. Let the fish tank water settle and gain room temperature [4].

🐡 What are Fish Tanks made of?

Most fish tanks are made of glass, but some are made of plastic, which is less susceptible to destruction than glass. It is also lighter (but has a costlier price tag) than glass. Also, get to know whether other materials (such as aluminum rims) are corrosion-resistant. This is crucial with a saltwater aquarium.

🐙 How long do Aquariums last?

Your fish tank will remain in good condition as long as you take good care of it. Some fish parents can use their tanks for decades. Keep in mind that glass aquariums tend to last longer than acrylic ones, but any type will last a long time if you take good care of it.
