Buying Guide For Best 55 Gallon Fish Tanks

55 gallon fish tanks are, let’s face it, quite large. Aquarists, fish-lovers, aquarium keepers—who have years of experience with smaller fish tanks, can definitely switch to a bigger tank like 55-gallon ones.

Not only will you fishy friends have a new and larger home but think of the countless number of ways you would be able to decorate the tank. Before you get too excited though, there are certain pointers that you must keep in mind before purchasing a 55-gallon tank.

After having purchased one, if you end up not liking it or feeling overwhelmed with such a large-sized tank, returning it might be a time-consuming process. Therefore make a wise and well-informed decision. Let’s take a look at those purchasing pointers:

1. Decide where you would want to keep it

55-gallon rectangular fish tanks are simply large, and they occupy a sufficient amount of space. Unless you have a separate facility for housing large fish tanks, you would want to position the big fish house in one corner of your living room or dining space.

Therefore, before you end up buying one, decide the most suitable spot in your house where the fish tank would find its location. Make sure wherever you decide to keep it, there should be abundant space at the front and back of the fish tank.

You, as the keeper, would have to spend a considerable amount of time feeding the fish or changing water, the latter being a time-consuming process. A sufficient front space will let you do that. A backspace would ensure that your hang-on-the-back filters get sufficient room.

Also, wherever you decide to locate your new aquarium, bear in mind that it is away from plugs and cords. In that way, if any water overflows or leakage happens, the risk of short-circuit will be minimized.

Another thing you might like to remember before settling on a location is if the place is easily accessible to the public. Yes! Such a beautiful reflective ornamental piece would go unnoticed by your friends and guests if you place it in a dark corridor or under the staircase.

Therefore place it in a location where people can admire its beauty and children can observe and learn about aquatic landscapes to take inspiration for their science lessons.

2. The right shape and dimensions

There are different sizes of fish tanks available. These variations could be a lifesaver for many aquarists and hobbyists. Traditional aquariums are mostly rectangular that consume a lot of space, and need to be kept either against a wall or against a flat surface. They are not at all suitable to be positioned in a corner.

However, thanks to the thoughtful manufacturers, nowadays hexagonal and cylindrical shaped aquariums are also available, and my, are they gorgeous! They are perfect for small spaces and corners.

They are also unique and refreshing for a change—just imagine the attention your adorable fish buddies are going to get after you shift them to one of these. With proper lighting and decorations, these differently-shaped aquariums would look other-worldly.

While, with the conventional square or rectangular fish tanks you only get a front and side view, with cylindrical tanks you would get a 360° view, depending upon where you have positioned it though.

Typical rectangular tanks come in dimensions of 40x39x54 inches, whereas hexagonal aquariums fall anywhere within 25x29x24 inches. So you can easily see the stark difference in the amount of space each is going to consume.

Rectangular behemoth aquariums are great for central decoration objects. On the other hand if you live alone in a space-efficient flat, and is struggling for space to keep a 55-gallon fish tank, you might as well go for a cylindrical or a hexagonal tank.

3. Does the tank come with all the right equipment?

If you do not have a separate aquarium-keeper who will maintain the 55-gallon tank for you, it would be better if you order all-in-one combo packs. You might not have enough time to go to the pet store and spend hours choosing the equipment or ornaments, so choose one that comes with pumps, filters, and light-fixtures.

At least make sure your aquarium has light fixtures and a good-enough filter mechanism to begin with, and a few months later, you can always customize and improvise.

Take a checklist with you of the number of equipment that are essential for the upkeep of a fish tank as large as a 55-gallon one. Here is a list of a common few must-haves in the fish tank combo pack:

  • Fish tank lid

Water overflow is a common dilemma but could prove to be dangerous if your fish tank is situated anywhere close to plugs or wires. Ensure your aquarium has a lid, more preferably, with light pockets or windows for light to enter.

If the lid can be opened or closed on sliders or hinges then it would be even better. Lids prevent water dripping, contaminants from outside to flow in, and keep the fish protected. The ones that can be opened and closed are quite useful in feeding the fish.

  • Cabinet or stand:

Cabinets are especially useful for storage and of course, to hold the aquarium in place. 55-gallon tanks need support, that’s for sure. Not all 55-gallon tanks come with a cabinet or stand, but if you order one that does, it would be very helpful for you.

Getting a compatible stand from the pet store might be a tad difficult, since there is a possibility that it might not be strong enough to withstand the weight of your fully-decorated and inhabited tank.

A 55-gallon tank may weigh anywhere between 70 and 80 lbs, and when fully occupied, it may weigh around 630 lbs. Hope you have got the point and would get yourself a sturdy build of a cabinet!

  • Heating mechanism and thermometer

Depending on the temperature conditions of your living place, this would be an aspect you might want to consider seriously. The source of water for your aquariums might be freezing cold in winter, especially if you are living in snow-covered areas or in the northern regions.

Having said that, you might also be living in a superbly hot or humid place—in which case you might want to keep track of the water temperatures at all times. Water temperature tracking will also help you predict and solve any possible causes of infestations.

  • Light fixtures

Fish do sleep, and their circadian rhythm stays in check when a proper routine of the hours of illumination and darkness is maintained. Too bright or too dim lights are a no-no for aquariums, and long exposures to sunlight or any other form of light is quite harmful in every possible way.

LED lights are great because they emit a soft glow and are usually available in white, blue and other natural-looking color variations.

  • Filtration mechanism

Most importantly—does your brand new aquarium come with a filter? It could be a simple filter, not the 3-stage one, but at least it would keep the water aerated and house multiplying populations of beneficial bacteria.

You need oxygen and bacteria for your 55-gallon fish tank—you cannot compromise with this under any condition


Q.1) What kind of fish can I add in a 55gallon fish tank?

Ans: Broadly speaking, you can categorize the fish in an aquarium based upon which segment of the aquarium they like to stay in mostly. Some like to live at the bottom of the aquarium and are therefore called the ‘bottom-dwellers’. They barely venture and swim in the higher segments of the water-columns.

Mostly are scavengers and are popularly known as the ‘cleaning crew’ in the aquarist community. Consider keeping Cory Catfish—you can feed them heavy food pellets, so that the food sink and reach the fish. Keep them in schools of fives or tens—a pack of ten would be more than sufficient for your 55 gallon tank.

Another bottom dweller could be Plecostomus or Pleco—they grow quite large and could be a bit aggressive when they grow older. Kuhli or Clown loaches could be another option of bottom-dweller species—as they are a bit bigger in size, so keeping them in packs of 5 should be enough. Cherry shrimp and Ghost shrimp could also be a popular choice.

Then come the mid-dwellers. These are fish populations that dare to swim in the upper water columns—an inch distant from the gravel, or as high as a few inches under the water surface. Gouramis could be a beautiful addition of mid-level fish in your 55-gallon tank.

Some Gouramis could be as long as 6-inches and could be a bit territorial though—so you might like to keep them in smaller populations. You can consider the Dwarf Gouramis instead—they are much smaller. Angelfish, Barbs and Tetras are other fish that you can keep in your list of considerations.

Neon Tetras are small and you can think about keeping packs of 20 in your 55-gallon tank. You can also think about housing some Cardinal or Bleeding Heart Tetra species. Cherry Barbs are beautiful—keeping six to eight of them would add a wondrous touch to your 55-gallon fish house.

Fish that prefer to swim in the topmost levels of the aquarium include Guppies, Sword-tails and Mollies, among others. Guppies will add a burst of color in your aquarium—watching them is a pleasure. Swords and Platys are great too—for every male Sword, keep two female Swords.

Mollies would be an excellent consideration too—you can think of keeping Lyretail or Sailfin Molly, among other species. Cute stripped Zebra Danios, Cyclids and Puffers would be refreshing additions too.

Q.2) What are the pros and cons of a 55 gallon aquarium?

Ans: Pros

  • 4-foot length and 21” height give a large viewing panel
  • All-in-one kits could be quite cheap—around $150
  • Contains all equipment, if not, compatible fixtures are easy to find
  • Highly customizable, you can decorate in any way you want
  • You can stock so many types of fish in it


  • Great in length and height but not in width—only 12.5” wide, less depth
  • Quite heavy when fully equipped—a stand is often difficult to find
  • You might end up spending a good 75$ to $100 for a separate stand
  • You might need more than one filter—high chances of infestation
  • Taller tanks are difficult to clean, light penetration is low

Q.3) How much do 55gallon tanks generally weigh?

Ans: A glass freshwater tank weighs around 487 lbs, while a lighter acrylic version weighs around 455 lbs. Glass saltwater tanks, however, weigh around 498 lbs, while their acrylic counterparts weigh 466 lbs.

Q.4) How do you clean a 55gallon tank properly?

Ans: If your 55-gallon has a proper filtration system, you would not need to worry about anything for a long time. Make sure that the filtration system is 3-stage—either the filtering mechanism may come included in the tank package, or if it is not, purchase all required components of it.

The 3-stage filtration process includes mechanical, chemical and biological filtration process. Mechanical filtration removes all kinds of larger and visible debris or floating dirt from the water.

Chemical filtration removes any chemicals from the water—like ammonia or nitrites, among other contaminants. Biological filtration houses population of useful bacteria that convert harmful ammonium compounds to benign nitrates.

Final Word

55-gallon fish tanks are humongous, and it takes a lot for a proper upkeep of the fish and the tank itself. But such large tanks can be customized to your heart’s content—just imagine the number of fish, plants and ornaments you could add to beautify it!
