Save Time and Money by Choosing the Best Fish Tank for Your Home


An astonishing 139 million freshwater fish are kept as pets in the United States. But how many of those are living in the best possible conditions?

Ensuring a healthy, lively environment for your aquatic friends goes beyond just feeding them on schedule. It starts with choosing the best fish tank.

A well-chosen fish tank contributes significantly to the wellbeing of your fish, the ease of maintenance, and even the aesthetic appeal of your home. Ready to dive in and discover how to choose the best fish tank for your needs? Read on to learn more.

Understand Your Needs

Before you can set up a perfect underwater world, you need to understand your needs. These needs will guide you in picking the right aquarium and fish.

First, ask yourself why you want a fish tank. Is it purely for the love of keeping fish, or are you looking to add a decorative element to your home?

Maybe it’s a bit of both. Knowing your purpose will help you decide on the best fish tank to suit your needs.

Next, consider the type of fish you want to keep. Freshwater fish and saltwater fish have different needs. If you’re just starting, a freshwater tank might be easier to maintain. Freshwater fish are typically more forgiving of fluctuations in water conditions.

On the other hand, saltwater fish offer a greater variety of colors and shapes, but they require a more complex setup and diligent care.

Space Availability

Finally, think about the space you have available. A fish tank can be as small as a 5-gallon nano tank or as large as a 500-gallon tank. But remember, the tank size will not only determine the number of fish you can keep but also the location of the tank in your home.

Bigger tanks require sturdy support, so plan accordingly. Remember, it’s not just about fitting the tank into your space, but also about leaving room for maintenance tasks like cleaning and feeding.

Important Fish Tank Features

Picking the best fish tank isn’t just about size and style. You’ll also need to think about the features that will keep your fish healthy and your tank looking great.

Size and Shape

Size matters when it comes to fish tanks. A larger tank generally means healthier fish. More water volume can dilute toxins and is more stable in terms of temperature and pH.

It’s a common myth that fish grow to the size of their tank. Fish will grow to their genetic size, and a too-small tank can stunt their growth and cause health problems.

The shape of the fish tank is also important. Longer, wider tanks are better than tall, narrow ones. Fish live and swim mostly in the middle and bottom of the tank and a wider area gives them more room to move around.


The material of your tank is another vital feature. Glass and acrylic are the most common materials.

Glass fish tanks are often cheaper, more scratch-resistant, and less likely to distort your view but they are heavier and have limited shapes. Acrylic fish tanks are lighter and can be molded into many shapes. They’re more impact-resistant, but they can scratch easily.

Filtration System

The filtration system is the heart of a healthy fish tank. It keeps the water clean, removing waste, excess food, and potentially harmful chemicals. There are three types of filtration: mechanical, chemical, and biological and a good aquarium filtration system will handle all three.

Mechanical filtration removes solid particles from the water. Chemical filtration uses activated carbon or other media to remove dissolved impurities. Biological filtration is the process where beneficial bacteria break down harmful ammonia and nitrites produced by fish waste.


Lighting plays a crucial role in displaying your tank’s beauty. It also contributes to the health of fish and any live plants in your tank.

LED lights are a popular choice because they’re energy-efficient and don’t generate much heat. If you’re setting up a saltwater tank with coral, you’ll need specialized lighting to promote coral growth.


Unless you’re keeping cold-water species, you’ll need a heater to maintain a stable water temperature. Fish are ectothermic, meaning their body temperature matches their environment.

Sudden changes can stress them and lead to illness. Heaters with built-in thermostats allow you to set the right temperature and forget about it.

Additional Accessories

Once you’ve chosen your aquarium, you’ll need to consider additional accessories. These extras help create a suitable environment for your fish and add a touch of personality to your fish tank.


Aquarium decor is about more than just aesthetics. Sure, a well-decorated tank can be a centerpiece in your home, but for your fish, these decorations provide much-needed hiding spots.

Consider using live plants, rocks, and other decor to mimic your fish’s natural habitat. They’ll appreciate the hideaways, and you’ll love the natural look.


The substrate is the material you put on the bottom of your tank. It plays a significant role in the health and happiness of your fish. If you have a freshwater tank, you might go for gravel or sand.

Some fish, like certain cichlids, prefer a sandy substrate where they can dig. Others, like live plants, need a nutrient-rich substrate to grow.

Air Pumps

Air pumps are another accessory to consider. They oxygenate the water, which is crucial for your fish’s survival. Air pumps also create water movement, preventing stagnation.

Plus, they power some types of filters and decorations. While not always necessary, especially if you have a good filter and live plants, they can be a beneficial addition to many setups.

Budget and Maintenance

One often overlooked aspect when choosing the best fish tank is understanding the associated costs and maintenance requirements. It’s essential to keep in mind that the initial purchase of an aquarium is just the beginning.

Initial Cost

The initial cost of setting up a fish tank can vary greatly. The price depends on the tank size, material, and the type of setup you choose.

A basic freshwater tank setup tends to be less expensive than a saltwater tank. Saltwater aquariums often require more specialized equipment and more expensive fish and invertebrates.

Besides the tank itself, you’ll need to budget for a stand, a good quality filtration system, lighting, a heater, decor, substrate, and of course, the fish. It’s a good idea to make a list of everything you’ll need and shop around for the best prices.

Maintenance Cost

While the initial cost can be quite high, don’t forget about ongoing maintenance costs. You’ll need to budget for things like fish food, replacement filter media, water conditioners, and electricity to run the tank. If you have a saltwater tank, you’ll also need to buy salt mix and possibly supplements for your invertebrates.

Time Commitment

Maintaining a fish tank takes time. Routine tasks include feeding the fish, cleaning the tank, testing the water, and monitoring the fish for signs of illness.

Larger tanks and saltwater tanks typically require more maintenance than smaller freshwater tanks. Make sure you’re ready for the commitment before you dive in.

Choosing the Right Fish for Your Tank

Once you’ve selected your ideal tank, it’s time to choose the right fish to inhabit it. This process is more complex than simply picking the most colorful or eye-catching species. It requires careful consideration of various factors to ensure a healthy and harmonious aquatic environment.


Not all fish get along. Some species are more aggressive, while others are peaceful. It’s essential to research each species’ temperament and social behavior before introducing them to your tank.

For example, bettas are often best kept alone due to their aggressive nature, while tetras tend to thrive in groups.

Size and Growth

Consider the adult size of the fish, not just their size at purchase. Many fish sold in stores are juveniles and can grow significantly larger.

Overcrowding can lead to stress, disease, and even shortened life spans. As a general rule, provide at least one gallon of water for each inch of fish.

Environment and Diet

Different species have different environmental requirements. Some pet fish need plenty of hiding spots, while others prefer open water for swimming.

The water’s pH, hardness, and temperature can also vary between species. Additionally, dietary needs can differ. Some fish are carnivorous, some are herbivorous, and others are omnivorous.


Finally, consider sustainability. Many popular aquarium fish are harvested from the wild, sometimes using methods that harm coral reefs or other fish populations.

Where possible, choose species that are bred in captivity. This practice not only supports the aquarium trade but also helps protect natural ecosystems.

Make Your Fish Feel at Home

The journey to becoming a successful fish owner starts with choosing the best fish tank. By considering your needs, understanding essential fish tank features, accounting for additional accessories, and assessing the budget, you can create a thriving environment for your aquatic pets.
