Why I Love My 20 Gallon Hex Fish Tank

I have been an avid fish keeper for many years and have had various sizes and shapes of fish tanks. However, when I first got my 20 gallon hex fish tank, I instantly fell in love with it. Here are a few reasons why I believe this tank is necessary for any fish enthusiast.

Firstly, the unique hexagonal shape of the tank adds a beautiful and eye-catching element to any room. It allows for a 360-degree view of the fish, making it a great centerpiece for any space. The shape also creates more surface area for the fish to swim and explore, promoting their overall health and well-being.

Furthermore, the 20 gallon size is perfect for a variety of fish species. It provides enough space for multiple fish to coexist comfortably while still being manageable in terms of maintenance. It also allows for more flexibility in creating different habitats within the tank, such as adding plants or decorations.

Another reason why this tank is necessary is its versatility. It can be used as a freshwater or saltwater tank, giving me the freedom to choose what type of aquatic creatures I want to keep. This has allowed me to expand my knowledge and experience in different types of environments

My Buying Guide on ’20 Gallon Hex Fish Tank’

As a fish enthusiast, I have had my fair share of experience with different types of fish tanks. However, when I decided to upgrade to a 20 gallon hex fish tank, I was overwhelmed with the choices available in the market. After thorough research and personal experience, I have compiled this buying guide to help you make an informed decision while purchasing a 20 gallon hex fish tank.

Size and Shape

The first thing to consider while buying a 20 gallon hex fish tank is its size and shape. The dimensions of a 20 gallon hex fish tank are usually 14x14x24 inches, making it taller and narrower than traditional rectangular tanks. This unique shape adds an interesting dimension to your home decor while providing ample swimming space for your fish.

Material

Another important factor to consider is the material of the tank. Glass and acrylic are the two commonly used materials for fish tanks. While glass tanks are more durable and scratch-resistant, acrylic tanks are lighter in weight and provide better clarity. If you have children or pets at home, it is advisable to go for a glass tank as it is less prone to scratches.

Filtration System

A good filtration system is crucial for maintaining the water quality in your fish tank. A 20 gallon hex tank requires a filter that can handle at least 5-10 times the volume of water in an hour. You can opt for either an internal or external filter depending on your preference and budget.

Lighting

Proper lighting is essential for the health and well-being of your fish and plants (if any). Most 20 gallon hex tanks come with built-in LED lights that provide sufficient lighting for basic freshwater setups. However, if you plan on keeping live plants or want to add a more aesthetic touch, you may need to invest in additional lighting.

Accessories

A fish tank is not complete without some accessories to enhance the overall look and provide a comfortable environment for your fish. You can add gravel, rocks, and plants to create a natural habitat for your fish. It is also important to have a thermometer, heater (if needed), and a water testing kit to maintain the ideal temperature and water parameters.

Budget

Last but not least, consider your budget while purchasing a 20 gallon hex tank. While it may seem like an expensive investment at first, it is important to remember that this tank will be home to living creatures that require proper care and maintenance. It is better to invest in a good quality tank with all the necessary equipment than opting for a cheaper option that may lead to problems in the long run.

In conclusion, purchasing a 20 gallon hex fish tank requires careful consideration of its size, material, filtration system, lighting, accessories, and budget. By keeping these factors in mind and doing thorough research, you can find the perfect tank for your aquatic pets. Happy fish-keeping!
