If you’re looking for the best aquarium and fish tanks that money can buy, you’ve come to the right place.

We’ve compiled this huge guide to home aquariums that every beginner, intermediate and advanced aquarist needs.

Whether you’re looking for the best nano aquarium, large fish tanks and even the best cheap aquariums, we’ve got everything you need right here — as well as a buying guide that will help prepare you for buying the best fish tanks for your precise needs.

Let’s get right into it.

Best Fish Tanks: Buying Guide

Before you dive right in and buy a tank, it’s worth considering a few things first.

Home aquariums can be expensive so you want to be sure that you’re buying the best one for you, your home and, most importantly, your fish.

Here’s what you need to consider before you buy.

best cheap fish tank

Aquarium Size

More important than anything else is how big you want your aquarium to be.

This will depend upon a couple of factors:

  • How much space you have
  • How many and what type of fish you’re planning to buy

Before you buy, it’s best to plan out exactly what fish you want in your home aquarium. You should research how big they grow to in adulthood, how much space they need to swim, if they’re better kept in groups, pairs or singles, and whether they’re compatible with tank mates.

We’ve compiled a couple of comprehensive guides to the best aquarium fish that covers all the above points:

  1. The Best Saltwater Aquarium Fish
  2. The Best Freshwater Aquarium Fish

If you’re planning on keeping big fish, or those that like a lot of open space for swimming, you’re going to need a big tank.

Thankfully, the best fish tanks are available in anything from 10 to 500 gallons — although you’ll probably only want to invest in the biggest if you’re a highly experienced aquarist!

Generally, as far as your budget allows, bigger is better when it comes to aquariums. This gives you plenty of flexibility of adding tankmates down the line.

Your number one takeaway should be: do your research and plan your aquarium before buying it.

Filtration Systems

Some home aquariums will come readily equipped with a filtration system, but others will require that you buy one separately.

While it’s generally easier and more convenient for beginner fish keepers to buy an all-in-one fish tank with a filter system, it can be beneficial to have to buy one separately.

A canister filter is a complex and sophisticated piece of kit, and experienced aquarists generally like to buy systems that can be customized to best serve their home aquarium. If you buy an all-in-one fish tank, you’re more or less stuck with the system for the life of the aquarium.

Of course, it will generally work out more expensive to buy the tank and the filter separately — particularly if you want to invest in the best canister filter — so bear that in mind when you’re calculating your set-up costs.

If you’re wondering whether you really need a filter system, aquarists almost universally agree that they’re a must-buy for any tank over 10 gallons. You’ll be doing your fish a disservice without one.

best nano aquarium


Just like filters, some fish tanks will come with lighting already installed and others you’ll have to buy this separately. Thankfully, these can generally be found for around $20 if you do need to buy them separately.

Again, this is another area where it really pays to have done your research beforehand: different fish have different lighting requirements. Bonus points for buying a lighting bracket that can be customized!

Not only is good lighting mandatory for your plants and fish to thrive, it also provides useful aesthetic benefits to your tank as well.

Material Construction

Another thing to consider is what your future fish tank is made from — glass or acrylic?

Here’s a table showing the differences between the two:

Strength & SupportVery strong and supportive, but often thicker than acrylicVery strong but often requires a stand and top support. Thinner than glass
CrackingWill crack under extreme forceWill only crack under unprecedented impact
WeightUp to 10x heavier than AcrylicLightweight
ScratchingDifficult to scratchScratches easily
Quality Over TimeMaintains clarity over timeCan yellow with age
Visual DistortionThicker the glass, the more light refracts = lots of distortionMinimal distortion, true size and color
CostUsually cheaperMore expensive

On the cheaper side of things, there are plastic fish tanks available but these are generally very small and also can’t be used with a filter. They’re not suitable for proper fishkeeping.

best large fish tank


No one ever said that being an aquarist was a cheap hobby!

There are quite a lot of large and small costs involved in setting up a home aquarium, which are best to be aware of before you go forking out most of your budget on the tank itself.

Here’s what you need to budget for:

  • Tank
  • Filter system and protein skimmer
  • Lighting
  • Water thermometer
  • Water heater
  • Chemical test kit
  • Live plants/reef
  • Decorations
  • Substrate
  • Fish
  • Fish food

If you’re just starting up, we recommend focusing on buying the best fish tank for beginners, a filter, lighting, hardy fish and fish food. Everything else can be added as you become more experienced and add more interesting fish to your aquarium.

Now, let’s get down to the rankings: the best home aquariums of 2020.

Best Nano Aquarium

If you’re a complete beginner to the world of fishkeeping, or you’re looking for a suitable starter fish tank for someone who is, we’d suggest a nano aquarium.

As the name suggests, these are essentially tiny aquariums — meant for a couple of small fish at most.

Their benefits lie in their small size — they can be kept on a desk or a cabinet — and their low prices. Perfect for beginners!

Here are a few of our favorites.

Marineland ML90609 Portrait Aquarium Kit, 5-Gallonir?t=fishcareguide 20&l=am2&o=1&a=B00O8SZTKQ The Best Fish Tanks Of 2022

best small aquariumbest nano aquarium
We think that this is far and away the best nano aquarium on the market right now.

With a 5 gallon capacity, it’s slightly bigger than its competitors and it’s more sophisticated too, with an advanced 3 stage filtration system with an adjustable flow filter pump hidden in the back panel. This means a high standard of water quality is available — almost unheard of in such a small fish tank!

The fact that you can adjust the flow of the pump also means that this makes for one of the best Betta fish tanks too.


  • 3-stage filter built in
  • Adjustable flow filter pump built in
  • Beautiful blue and white, energy efficient LED lighting
  • Sliding glass canopy allows for easy access
  • Rounded corners for unobstructed visuals
  • Marineland is a highly respected manufacturer
  • Easy to assemble and maintain
  • Lightweight at 12 lbs
  • Tall — great for adding plants and ornaments


  • Cover isn’t totally air tight — small escape artists may be able to crawl out if not monitored

It’s hard to resist this cute little nano aquarium with a built-in waterfall!

Mini USB LCD Desktop Lamp Light Fish Tank Aquarium, 0.4 Gallons

best small fish tank

This is probably the smallest desktop aquarium that we’ve ever come across — but it’s awesomely innovative! Just make sure that you don’t overcrowd it.

Despite its low price, this truly nano aquarium has got a lot of cool features, including a large, bright LCD screen that shows the date, time, temperature and has alarm functions. It’s pretty limited however as the recirculation of water is powered by USB. The screen is powered separately by batteries.


  • Large, bright screen
  • Comes with decorative peebles, plants and a USB cable
  • Multiple functions as a desktop device: alarm clock, thermometer, pen holder
  • Also has 6 nature music sounds
  • recirculating water
  • Cute design


  • We think this is far too small for a fish to thrive
  • Thermometer is not a water thermometer

Best Fish Tanks: 10-55 Gallons

These small and mid-sized aquariums are the next step up from nano aquariums, and the products you should be looking at if you’re seriously interested in fish keeping.

These sized tanks will easily serve any beginner aquarist, while those at the larger end — particularly 50 gallons and up — will be perfect for intermediate ones too.

  • Long-lasting and energy efficient LED light built into canopy
  • Comes with fish food, water conditioner, biological supplement, fish net and care guide: perfect for beginners

If you’re a committed and experienced aquarist who is happy to invest some serious time and money into your hobby, then you’ve likely considered buying a large aquarium to house your fish.
