Best 55-Gallon Tank – Review & Guide

Maybe its time to move up to a larger tank.  Perhaps you are just getting started and are exploring your options.  Either way, an aquarium in the 55-gallon range provides a host of options.

This is an ideal tank size for just about any kind of habitat you are trying to replicate.  55-gallon tanks can support saltwater, freshwater, plants, breeding, and much more.

Tanks smaller than 55-gallons may only support one school.  Once you get into this range of tank size, though, you can begin to look at supporting multiple small schools of fish.

When looking at 55-gallon tanks you’ll want to ensure it’s well-built and has the features you are looking for.  There are a lot of options out there, from the all-in-one kit to much simpler.  Let’s look at some of the best we’ve found.

How to Select a 55-Gallon Tank?

Purchasing a 55-gallon tank represents a significant investment in the fish-keeping hobby.  Therefore, it’s not unreasonable to take the time to research every step in the process.  Clearly, one of the most important things you’ll need to do is select the right tank.

Let’s start with an easy one.  Do you have enough space for a 55-gallon tank?  More than likely, the tank you pick won’t fit on a desk or bookshelf.  That’s not the only size consideration, though.

When looking at tank measurements, don’t rely on the tank dimensions alone.  Consider the stand and hood size, too.  Does the tank/stand combo your looking at have any decorative trim sticking out from the sides?  Is the height of the hood included in the overall dimensions?  A quick call to customer service could save you a real hassle trying to return or replace your tank.

As you do your research, you’ll notice that many tanks will often include accessories.  Ultimately, you’ll need to decide whether you want to piece together your aquarium or buy a kit.  There can be advantages and disadvantages to both.

If you are a beginner, a kit can be very helpful.  A good starter kit will literally include everything you need to get going.  Often (but not always), these starter kits will include the bare minimum equipment.  That’s not necessarily a bad thing if you are still learning the ropes.

Seasoned aquarists will likely already have proven accessories that they swear by.  If that’s the case, avoid buying kits and just look for a quality tank.

Finally, the age-old question.  What’s better- glass or acrylic?  To keep it short, I’ll summarize the pros and cons.  Glass tanks are generally cheaper and more resistant to scratching.  They weigh a lot more than their acrylic counterparts, though.

Acrylic tanks are more easily scratched.  This usually occurs when beginners are cleaning their tanks improperly.  Acrylic tanks come in a wider variety of shapes due to the ease of which the plastic can be bent.  An acrylic tank is much less likely to shatter.  However, some acrylic tanks will yellow with age.

How to Set Up Your 55-Gallon Tank?

So, you’ve decided what tank to get and you’ve made your purchase.  Now you’ll need to make sure it’s properly set up.

Make sure your tank is placed in an area where its temperature is likely to remain stable.  Don’t put it near windows or vents.  Sunlight on your tank will increase temperatures and increase the likelihood of growing unwanted algae.

Build or install your aquarium stand.  Be especially careful if the stand didn’t come with the tank.  It can be surprising how much your tank will weigh after its all set up.  Regardless of whether you buy a glass or acrylic tank, water weighs 8.3-pounds per gallon.  That means your tank could weigh over 500 pounds once you’ve added everything to it.

Once you’re confident with the stand you can add the aquarium.  Wash it out thoroughly with plain water.  Soaps or other cleaning agents could leave behind residue in your tank.

Next, add your clean substrate.  There are so many options for what you put on the bottom but there are a couple quick ways to calculate how much you need.  The first way is to add one pound of substrate per gallon of water.  The other way is to add enough to make a two-inch layer on the bottom.  Because different materials have varying mass, the two-inch rule may work better for you.

Now, fill that tank up!  Use room temperature water and include any water treatment you are using.  If you haven’t put in all your plants and decorations don’t fill the tank all the way.  It’s easier to add more later than to find all the towels in your house.

Start putting in all over your filters, heaters, bubblers, and any other electronic gizmos.  Once that’s done add any lights or hood.  Now you can plug everything in and let it run.  As the tank sits it will begin to grow bacteria that will help eat fish waste.  You can’t put fish in right away or their water will probably become cloudy.

How to Maintain Your 55-Gallon Tank?

Maintaining any type of aquarium requires attention to detail, discipline, and patience.  You’ll need to learn signs of trouble before they become epidemic.  You’ll be part Sherlock Holmes and part janitor.  Haven’t quit reading yet?  Good.  Every tank will have its own quirks and characteristics but there is some basic preventative maintenance you can do regardless.

Change the water every week.  Well, not all of it.  For a 55-gallon tank look to change about 20-30% of the water each week.  This ensures you’re not removing all of the useful bacteria at once.  You may decide to get a water vacuum that will remove water while sucking up unwanted debris.  This is nice but not required.

On different weeks you can add other cleaning to the tank.  For example, one week you may change the water AND clean the substrate.  The next week you might change the water AND clean the filter.  A 55-gallon tank is pretty forgiving when it comes to pollution build up so you can spread out your tasks a little bit.

Finally, don’t forget to test your water.  Water test kits are widely available, and you’ll quickly find one you prefer.  The test kit will tell you what the ammonia, nitrite, and nitrate reading are for your water.  Based on the feedback from your test kit, you can make the necessary adjustments to get the water back to perfect.

Best Fish for a 55-Gallon Tank?

Now for the fun part!  What are some good fish to move into your 55-gallon tank?  First, decide whether you are running a saltwater or freshwater tank.  It’s generally recommended that beginners start with freshwater tanks because they require less upkeep.  For that reason, we will start with freshwater fish and then move on to saltwater.

You can really go one of two ways with your selection.  A 55-gallon tank will support schools of small fish or fewer larger ones.  The large tank will invite your schools to swim around in interesting patterns that are sure to be fun to watch.  Good schooling species include Neon Tetras, Glass Catfish, and Guppies.  A combination of these schools can make for very interesting displays.

Larger fish types might include Pearl Gourami.  These would be ideal for a tank that has plenty of live plants.  They play well with Tetras, too.  Another larger species option are Cichlids.  While often aggressive, a larger tank may provide everyone enough room to live and let live.

Good saltwater species must include Clownfish.  They will be the centerpiece to your tank and are recommended to saltwater tank beginners.  Wrasses are another easy pick due to the wide variety of colors they come in.  Some species will even eat parasites from other fish.

Make sure that the fish and plant combinations you pick can all live together peacefully.  Regardless of species, it’s always a good idea to quarantine new fish for a few days in a separate tank.  This ensures they aren’t bringing anything weird into your tank.  Add new fish a couple at a time to allow the tank environment to adjust.


So here we are.  You are now armed with the knowledge to make smart decisions on the best 55-gallon tank to meet your needs.  We’ve covered how to set it up, maintain it, and stock it.

Whether you are a beginner or veteran looking for a kit or standalone tank you can now decide with confidence.  This tank size offers many benefits not available in smaller sizes.  A 55-gallon tank allows you to really create that ideal aquarium you have in your mind’s eye.
