75 Gallon Aquarium: Our 5 Finest Picks

A 75 gallon aquarium is one of the larger home tanks you can choose, and a setup this size gives you a wide range of choices in choosing the types of fish to keep. Larger tanks mean you can choose to house larger tanks in a species-specific aquarium, or keep schools of smaller, more colorful fish to create a swirling kaleidoscope of brilliance that is sure to be a focal point in your home.

It's an urban myth to assume that a small tank is easier to maintain. While a 10 gallon or nanotank might seem like a more manageable option at first, larger aquariums are actually easier to care for and manage. This is because the more water there is in the tank, the more water conditions are likely to be more stable. So you can see that a 75 gallon aquarium is the perfect size for both seasoned hobbyists and beginners.

In this guide, we've reviewed five of the best 75-gallon aquariums out there right now. Once you've chosen your tank, you'll want some ideas on what species to keep in it, and we have some inspiration for you on that too!

What does a 75 gallon tank weigh?

Storing your aquarium is critical to the safety of your fish, your family and your home.

If you put the tank in a place that is too hot or too cold, the health of the fish will suffer. Placing the aquarium on a thin piece of furniture or a weak floor can cause the entire property to fall to the bottom and shatter. If you place your aquarium in the middle of a room or too close to a door, small children or pets could run into the aquarium, possibly injuring themselves and knocking the aquarium over.

The weight of your aquarium also determines where you place it. Ideally, you should place a large aquarium on top of a suitable piece of furniture that will support the weight.

A 75 gallon tank is large, typically measuring about 48 x 18 x 24 inches for a rectangular fish tank. And a big tank is heavy too. A traditional 75 gallon glass aquarium weighs about 140 pounds when empty and at least 850 pounds in water. You'll also need to consider extra weight for decorations, plants, and fish.

What equipment do you need?

Most large aquariums don't come with any other equipment, so you'll need to purchase what you need separately. Although this will add to the cost of your setup, purchasing an additional kit will allow you to customize the setup exactly to your liking.

So what kind of equipment are you likely to need for your new 75 gallon fish tank?

Filtration system

Regardless of its size, every aquarium needs a filter system. The filter is vital to the health and cleanliness of your tank. It removes dirt from the water, houses beneficial bacteria that process harmful substances such as ammonia, nitrites and nitrates, and helps aerate the water.

When choosing a filter, make sure that the device is powerful enough to circulate all of the water in the tank at least four times per hour. There are a few different types of filters to choose from, although canister filters are probably best suited for a large tank.


If you want to keep tropical fish, you need a heater. Again, there are plenty of heaters to choose from, but you'll need one of at least 300W to evenly heat the water in a large tank.

Ideally, you should place the heater near the filter pump so that the heated water circulates most efficiently in the tank.

You will also need an aquarium thermometer to monitor the water temperature.

Lighting unit

Some aquariums are equipped with an integrated lighting unit in the tank lid or in the hood. However, if the tank you choose doesn't have it, then you'll need to buy one.

When choosing lights, keep in mind that some fish do not appreciate bright lights, while some species of plants require high levels of light to thrive. So think about which livestock you want to keep before you decide on a lighting unit.

Aquarium stand

As mentioned earlier, you should store a large aquarium on a specially constructed stand that will support the weight of the aquarium.

Some aquariums are equipped with stands. This is the most affordable way to buy one. However, you can also build your own stand if you are good at home improvement.

Tank cap or hood

If the tank you choose doesn't come with a hood or lid, consider buying one. Lids are important for several reasons:

  • Some fish have a tendency to jump, and a tight-fitting lid will keep your pets from escaping.
  • A lid keeps dust, flies, and curious pets and children's fingers out of the tank.
  • A lid slows down the evaporation process.
  • A tank hood houses your lighting unit.
  • A hood can help keep the heat in the tank.

Make sure your chosen lid has a feeding hatch so you can easily feed your fish.

75 gallon aquarium stocking ideas

One of the great things about having a large tank is that you can keep a nice selection of fish, including a larger specimen or two to make the setup more dramatic. You can even choose an oversized fish kept in a single sample container complemented by resourceful aquascaping and planting.

However, most people opt for a community setup. Before buying your fish, you need to do a lot of research to make sure you choose species that are compatible in terms of their behavior, diet, habitat, and water parameters.

You should also keep in mind that the young fish that you typically find in fish stores can get much larger when fully mature. Ideally, you don't want to buy tiny fish to mix with larger species as the little boys might end up as lunch! Choose fish species that are also in different areas of the water column. This avoids potential competition for the territory and helps create measures throughout the habitat.

Here on our website you will find a lot of information and suggestions. You can also get advice from your local fish shop.

Cold water tanks

When deciding on a cold water aquarium, your options are more limited than with a tropical facility. However, there are plenty of cold water fish to trap, such as: B. chic goldfish, zebra danios and weather loaches. Also, white cloud minnows and some types of barbs tolerate cooler water conditions.

Tropical tanks

When it comes to choosing tropical fish species for inclusion in a 75 gallon aquarium, the world is your oyster!

You can create a nice setup with lots of activity and color by mixing several schools of different Tetra species together. For added color and interest, try adding a small group of five or six dwarf gouramis, or maybe some live porters like mollies, platys, or swordtails. Corydora's Catfish is a cute and easy-care addition to add interest at the bottom of the tank.

Many species of tropical fish are also easy to breed, so investing in a smaller spawning tank to expand your hobby may even allow you to increase your own population.

Sea and reef pools

While keeping marine species is more difficult and requires more specialized equipment than for cold water or tropical pools, the range of colors and shapes of creatures is incredible.

You can keep it simple and opt for a fish-only aquarium, or you might prefer to spice it up by including invertebrates like shrimp, crabs, and other crustaceans in the setup. If you hold a reef tank, you can enjoy live stones, corals, sponges, anemones, as well as fish and invertebrates.


A 75 gallon aquarium gives you plenty of headroom to keep a variety of fish species and branch out into marines or a reef tank if you feel like the challenge.

All the tanks we have reviewed are considered to be of high quality and will provide your fish with a comfortable, spacious home for many years to come. As with most large tanks, you will have to purchase most of the additional equipment that you will need separately because larger aquariums usually do not come as a kit. However, this allows you to create a completely custom setup that will perfectly suit your selection of fish and plants.
