Generally, the size of your corner aquarium will be determined by the space available in your home, your budget, and the type of aquatic life you plan to keep. Remember, larger tanks are always better for the health and well-being of your aquatic pets, as they provide more space to swim and grow.

If you are considering setting up a corner aquarium in your home, finding the ideal location for it is crucial. Proper placement not only ensures the optimal health and well-being of your fish but also enhances the aesthetic value of the aquarium.

Here are some factors to consider when deciding where to place a corner aquarium.

A Firm Foundation

Corner aquariums can be heavy, and even a small one can weigh over 50 pounds when filled with water. Therefore, the first step in setting up a corner aquarium is ensuring that you have a sturdy and stable foundation to support it.

It is advisable to use an aquarium stand that can hold the weight of the tank. The aquarium’s stand should be level and able to withstand the weight and pressure of the water.

Level Ground

Aquariums should always be placed on a level surface. Uneven surfaces can cause the aquarium to tilt, creating unnecessary stress on the glass or acrylic.

An uneven tank can also shift or crack the seal of the cover glass, leading to a potential water leak. Use a spirit level to make sure that the aquarium is placed on a leveled surface.


Excessive sunlight can cause issues for your fish and plants. The direct sunlight can raise the temperature of the water, leading to temperature shocks and discomfort to your fish.

Sunlight can also promote the growth of algae, which can become a breeding ground for bacteria, leading to water contamination. Therefore, you should avoid placing your corner aquarium next to windows or areas that receive direct sunlight.

Peace and Quiet

Aquariums should be placed in a peaceful area without excessive vibrations or noise. Fish can get easily stressed by vibrations and noise from equipment, footsteps, or barking dogs.

Placing the aquarium in a peaceful area can ensure the comfort and well-being of your fish. Additionally, keeping the aquarium away from high traffic areas can prevent accidental bumps and spills.

Electrical Sockets

Having easy access to an electrical socket can save you a lot of trouble in the long run. Your aquarium needs electricity to power the heater, lights, and filtration system.

Ideally, you should place your aquarium near an electrical socket, but be sure to keep the wires organized to avoid any tripping hazards. You should also consider using a Ground Fault Circuit Interrupter (GFCI) outlet, as it provides an extra layer of safety against the risk of electrical hazards.

4) How Do I Clean a Corner Fish Tank? Cleaning your corner aquarium regularly is essential for keeping the water healthy and clear.

Proper cleaning and maintenance can ensure the well-being of your aquatic pets and maintain the aesthetic value of the aquarium. Here are some tips on how to clean a corner fish tank properly.

Cleaning the Viewing Pane

The viewing panel of a corner aquarium is typically made of curved glass, which can be difficult to clean. A magnet algae scraper or acrylic-safe magnet cleaner is a useful tool for cleaning the curved glass.

Place the algae scraper or magnet cleaner on the outside of the tank, wet the inside surface of the glass, and move the tool around to clean the glass. It is essential not to use abrasive materials like steel wool or a razor blade on the glass, as those can scratch and damage the surface.

Maintaining Water Cleanliness

Maintaining the cleanliness of the tank water is essential for the longevity of your aquatic pets. Regular water changes will ensure the quality of the water is not compromised and keep the aquarium clean.

A general rule of thumb is to replace 10% to 15% of the water in the tank weekly. This helps reduce the buildup of harmful chemicals and reduces the stress on your fish.

You should also clean the filter media regularly to keep the water clean and clear. The filter media should be replaced or cleaned when it becomes clogged with debris.

In conclusion, setting up and maintaining a corner aquarium requires specific considerations. When choosing a location for your tank, ensure that it is stable and level, placed away from direct sunlight or noise sources, and near an electrical socket.

Cleaning your aquarium involves regular water changes and the use of appropriate tools and solutions. Cleaning the curved viewing glass can be challenging, but with the right tools, you can clean it with ease.

5) Glass vs. Acrylic Corner Aquariums

When it comes to choosing a corner aquarium, the type of material is an essential consideration.

Glass and acrylic are the two most common materials used to make corner tanks. Both have their pros and cons, and understanding them can help you make an informed decision.


Glass aquariums have been around for centuries and are, therefore, the cheaper option. Although their prices vary and can depend on the size and style of the tank, glass aquariums are generally less expensive than their acrylic counterparts.

Acrylic aquariums, on the other hand, are a more recent development and have a higher manufacturing cost. This higher cost is usually reflected in the price.

Scratch Resistance

Acrylic aquariums are more susceptible to scratches than glass aquariums. However, scratches on acrylic tanks can be easily buffed out with sandpaper and polish.

Glass aquariums, once scratched, are often permanent. Careful handling and maintenance can prevent scratching in both types of tanks.

Tank Weight

Acrylic aquariums weigh about half as much as an equivalent glass aquarium. Therefore, acrylic tanks are a suitable choice for those who do not want to risk any issues with the stability of the support surface.

Glass aquariums, on the other hand, are heavy and require a solid and sturdy foundation to support their weight.

Aquarium Design

Both glass and acrylic corner tanks are available in different designs, such as curved or rectangular. However, for a curved corner aquarium, acrylic is the better option.

Acrylic is a flexible material that can be bent and shaped without breaking, making it ideal for creating curved designs. Glass, on the other hand, is rigid and cannot be molded into curved shapes, making it difficult to create a curved corner aquarium.

Safety in the Home

Acrylic has a higher impact resistance than glass. This means that if an acrylic tank was to fall and crack, it would be less likely to shatter than a glass aquarium.

Acrylic is also less likely to cause any harm to pets or children if it does get damaged. Glass, on the other hand, can break into sharp shards that are dangerous if ingested or stepped on.



A small corner aquarium is a great way to add a touch of elegance and uniqueness to your living space. The advantages of a small corner aquarium include their space-saving design and ease of maintenance.

When choosing a corner aquarium, you need to consider factors like the type of material you prefer, the price, the potential for scratching, the weight of the tank, its design, and the safety of the material used. In conclusion, both glass and acrylic corner aquariums have their advantages and disadvantages.

Choosing one over the other ultimately depends on your personal preference and budget considerations. Whichever type of material you choose, proper care and maintenance are essential to ensure your fish thrive and your aquarium looks its best.

Remember to always research before purchasing, set up carefully and enjoy your corner aquarium!

In summary, a corner aquarium is an excellent choice for adding a unique and attractive element to your living space. Factors like the type of material used, pricing, scratch resistance, weight, design, and safety must be considered when choosing a corner aquarium.

Whether you choose glass or acrylic, regular maintenance and care are essential for the optimal health of your fish and the overall aesthetic value of the aquarium. The benefits of a small corner aquarium include their space-saving design and ease of maintenance.

Proper placement and cleaning ensure the well-being of your aquatic pets. Ultimately, a well-maintained corner aquarium can transform any room into a beautiful and calming oasis.
