The first nano aquarium you should check out is the MarineLand Portrait Glass LED Aquarium.

This is a 5-gallon nano aquarium that weighs around 12 pounds. As you can probably tell from this aquarium’s capacity, it’s pretty small and doesn’t take up a whole lot of space. Which makes it great for people with limited space in their house.

This isn’t just a plain and simple nano aquarium, it comes with a few bells and whistles.

There are LED lights hanging over this aquarium’s curved frame. The lighting system offers two light settings. The white light setting is ideal for daytime as it helps enhance natural light. While the blue light setting enhances the view of the aquarium at night.

Features a 3 Stage Filtration System

The MarineLand ML90609 features a 3-stage filtration system that can be found in the back of the tank. The great thing about this filtration system is that it’s fully customizable.

So if you feel like changing something about it, you can do it with ease. You’ll find the pump, bio-media, and the cartridges inside the filtration chambers.

This aquarium is designed for ease of use. If you’re trying to feed the fish or clean the aquarium, all you need to do is slide the canopy cover to the back. However, you won’t often need to clean it as the filtration system does its job perfectly. There’s also a filter cartridge that’s specifically in there to get rid of dust, dirt, and debris.

The cartridges feature a molded ribbed back and it includes activated carbon. Its design helps increase the contact between the water in the aquarium and the carbon within it. Which allows it to get rid of odors and impurities in the water.

There’s also a bio-foam that effectively gets rid of organic particles and helps cultivate beneficial bacteria that eliminate ammonia and nitrites.

PROS:

  • The combination of the curved glass and black stand look great
  • It can be placed almost anywhere as it features a small footprint
  • All of its wires and cords are completely hidden from your view
  • The operation of both the filtration system and the pump is silent
  • The intensity of the LED lights is appropriate for keeping plants
  • Contender for the best nano aquarium

CONS:

  • The flow generated by the filter can be too strong for some fish
  • The stand is made entirely from plastic which can scratch easily

The Panaview aquarium from Koller Products is an ideal tank for children. It boasts 7 LED lights, each of a different color. You’ve got aqua, amber, red, purple, green, blue, and white.

This array of colors, when coupled with the sleek construction of the aquarium itself, gives out a modern and stylish look that can boost the aesthetics of any room. It’s truly dazzling.

This nano aquarium houses a fairly powerful internal filter that’s able to purify water at a rate of 45 gallons per hour. Which is incredible for a 5-gallon tank.

Considering that 120 gallons per hour is the recommended rate for 30-gallon tanks. When it comes to eliminating organic pollutants in the likes of heavy metals, odors, and colors, this filter does an outstanding job.

Made of Impact-Resistant Plastic

This aquarium is made of impact-resistant plastic. Now, we’re not really fans of plastic tanks as they tend to lack the clarity that glass offers.

However, this is one of the few aquariums that has a crystal-clear plastic frame. So basically, you get the durability of plastic without compromising on clarity. The Panaview’s rugged frame makes it an ideal saltwater nano tank.

We love that this aquarium has a small footstep. Which allows you to incorporate it anywhere, be it your office, bedroom, or living room.

Additionally, this is one of the easiest nano aquariums to set up and maintain. Further, the kit includes fish food so you can start feeding the fish right out of the gate. The food included is ideal for tropical fish.

PROS:

  • Equipped with 7 different-color LED lights that create a dazzling view
  • The aquarium is made of impact-resistant plastic that’s crystal-clear
  • It features a built-in power filter that boasts a remarkable flow rate
  • The Bio-Chem Zorb 10 resin-carbon filter is completely eco-friendly

CONS:

  • While the filtration system isn’t that loud, it’s certainly not quiet at all
  • The LED strip isn’t really waterproof, so you may need to buy new lights

This nano aquarium is available in a 6- and 12-gallon models. Regardless of which one you decide to buy. You’re guaranteed a compact construction that can easily be fitted anywhere in your home. You just need to figure out how many fish you want to put in there.

This aquarium features a 3-step filtration system that’s hidden out of sight in the pedestal. So that it doesn’t take away anything from the view of the aquarium.

This system incorporates chemical, biological, and mechanical means of filtration. Ensuring that the water in the aquarium is always clean. And that your fish’s health isn’t put in jeopardy by contaminated water.

Up to 42 LED Bulbs

The number of LED bulbs in the Fluval Edge varies from one model to another. The 6-gallon unit features 21 LED bulbs and the 12-gallon model features 42 LEDs.

The Fluval Edge offers 3 light settings in both of its models: Bright Daytime, Blue Nighttime, and Off. With such an impressive number of bulbs in both tanks, you can easily grow some plants in there.

We love the whisper-quiet performance of the water-circulating pump inside the aquarium. You’ll barely be able to hear it unless you’re standing next to the tank. It pumps the water through the filter in order to go through its 3-stage process. Then the water comes out completely clean. This isn’t only crucial for the livelihood of your fish, but for the health of your plants if you have any.

As far as installation and maintenance, the Fluval Edge can be easily assembled and set up in a matter of minutes. It features a removable cover that allows for easy cleaning and prevents the aquarium from overheating.

The cover also allows you to access the filter with ease. Overall, the Fluval Edge is a visually stunning nano aquarium that features everything you may need.

PROS:

  • Definitely one of the best-looking nano aquariums on the market
  • Equipped with an extremely-effective, 3-stage filtration system
  • Both of its models feature an impressive number of LED bulbs
  • The performance of the circulating pump and filter is very quiet
  • Assembling and setting this nano aquarium up takes little time

  • The LED lights are only adequate for low to medium light plants
  • We think this aquarium is a little overpriced compared to others

Last update on 2021-09-21 at 22:32 / Affiliate links / Images from Amazon Product Advertising API

A second entry on our list from Fluval with one of the most popular 5-gallon tanks on the market today. The Spec V. This aquarium boasts the same aesthetic beauty that Fluval is known for.

The aluminum trim and etched glass give it a very premium look. Especially when you turn on the 37 LED bulbs that it features. It’s not all about aesthetics with the Spec V, though.

When it comes to keeping the water clean and getting rid of contaminants, the Spec V is one of the best.

The 3-stage filtration system is simply superior to a lot of other systems found in other tanks. It also features a foam block that helps catch dirt and debris. BioMax Bio rings that help cultivate good bacteria. And activated carbon for eliminating chemicals and impurities.

One of the Quitest Filtration Systems

If you’ve dabbled with filtration systems before, you know how loud they can get at times.

Well, you’ll be happy to know that the filter equipped within the Spec V is one of the quietest. So you can actually put it in your bedroom and you’ll still be able to sleep very well. The position of the filter allows for easy cleaning and maintaining. You can find it built-in on the side of the tank.

Both the cords and the filter are somewhat hidden so that they don’t mess with the tank’s look.

Betta owners should rejoice.

Because the filter allows you to control the current inside of the aquarium to your liking. The aquarium also has a special compartment where the heater is kept hidden just like the filtration system. This thing would make a great desktop aquarium.

PROS:

  • This aquarium solidifies the fact that Fluval makes great-looking tanks
  • It houses one of the quietest filtration systems found in nano aquariums
  • It features strong LEDs and a large footprint, making it great for plants
  • The filtration system allows you to control the current in the aquarium
  • Contender for the best nano aquarium

CONS:

  • Simple to setup and maintain, looks great in any room
  • Sleek, low profile LED energy efficient light hood with feeding hole
  • Includes Aqueon QuietFlow filtration as well as food and water care samples
  • Ships in its own container for protection against scratches and breakage during shipping

Last update on 2021-09-22 at 05:31 / Affiliate links / Images from Amazon Product Advertising API

The Aqueon Minibow is a compact aquarium that has a modern design and an elevated base. It’s mainly designed for Betta fish, but that doesn’t mean you can’t put other species in it.

The tank is available in a variety of sizes that range from 1 gallon to 5 gallons. So you’re certainly going to find the ideal size that integrated perfectly with the space confines of the room.

The aquarium is equipped with low-profile LED lights that you can find beneath the hood. They’re pretty energy-efficient and will provide a good view of the aquarium.

However, the light intensity isn’t all that impressive. So we doubt that growing plants in the tank will be a good idea. There’s a feeding hole in the hood that you can use to feed fish without having to remove the hood itself.

One of the Best Desktop Aquariums

The MiniBow houses the Quiet Flow filtration system. Which doesn’t only clean up your aquarium from contaminants. But it also helps distribute the food around.

This aquarium has a pretty small footprint. So you can put it in tighter places such as dorm rooms or use it as a desktop aquarium. It’s also built for beginners, so setting it up won’t be much of a hassle for you.

The thing about a lot of aquariums and fish tanks is that they often get damaged during shipping and they end up delivered in a not-so-usable form. To avoid such inconvenience which not only bothers customers but also forces the manufacturer to replace the damaged product,

Aqueon ships its products in protective containers of their own to prevent scratches and breakage.

PROS:

  • Has a relatively small footprint that makes it very compact
  • Available in a range of different nano sizes for convenience
  • One of the best-looking nano aquariums in its price range
  • It’s designed for beginners so it’s extremely easy to set up
  • Contender for the best desktop aquarium

CONS:

  • While it’s very quiet, the filtration system isn’t that effective
  • The current from the filter can be too strong for small fish

Tetra is a household name in the aquarium industry. The brand is known for its high-quality and reliable tanks. And the Crescent Acrylic line is no different.

This aquarium is an ideal choice for people who aren’t fans of glass aquariums. It has a water capacity of 5 gallons. And it features a seamless curved front that has a super clear cover and a black base frame.

Let’s start from the top.

The Tetra Crescent Acrylic Aquarium features built-in, energy-efficient light bulbs that are designed to illuminate every inch of the aquarium when turned on. They’re also hidden from view so the only thing you can see is the light they’re emitting. In fact, all the cords and wires are hidden out of sight and you’re just left with the beauty of the tank itself.

The aquarium also features a built-in filtration system. That’s highly effective at keeping the tank and the water within it free of contaminants that can affect the health of the fish negatively.

The filer incorporates activated carbon in order to get rid of odors and discolorations in the water too. Not only is the filtration system effective, but it’s also whisper-quiet.

Curved Screen

The thing we really love about this tank is its beautiful curved screen. Not only does it look great. But it also helps optimize the viewing area effectively in order for you to observe the fish. Especially when you turn the LED lights on.

The number of positive reviews and satisfied customers is a clear indication of why this is a highly popular nano aquarium.

PROS:

  • One of the most lightweight and compact aquariums on the market
  • The integrated filtration system is arguably the quietest on this list
  • The curved front screen and LEDs give this thank a marvelous look
  • Has all the features of an expensive tank while being very affordable

CONS:

  • Some users reported that the LEDs stopped working after a while
  • The cover doesn’t provide enough security as it comes off very easily

If you’re looking for a nano aquarium that will be the focal point of the room, this aquarium from Aqueon is exactly what you’re looking for.

This kit includes a 5.5-gallon aquarium that has pink silicone in each corner that helps make it watertight.

The aquarium has a low-profile cover that will keep jumpy fish from getting out of the tank. It can easily fit under shelves and cabinets.

Just like all the aquarium kits on our list, the Aqueon LED NeoGlow Aquarium comes with a filter and cartridge.

The QuietFlow E Filter 10 features a small bow design that allows for an optimal performance. That will help keep your aquarium in peak condition without making much noise. In the cartridge, you’ll find activated carbon that effectively eliminates odors and discolorations.

Most Impressive in Terms of Lightning and Visual appeal

The lid is equipped with fluorescent LED lights of the color blue. When on, those lights create a vivid, ultra-clear view of the aquarium and its inhabitants. Not only that, but they also keep the pink seams highlighted for enhanced aesthetics.

We have to say that, in our opinion, this is the most impressive aquarium kit in terms of lighting and visual appeal.

We really love the black background that the Aqueon aquarium features.

When combined with the fluorescent light, it helps highlight and bring out the tiny details in your fish and plant life. It also helps camouflage the cords and connections of the filter and the LED bulbs. Allowing for a clear and crisp view of your aquarium without seeing the technical side of it.

PROS:

  • The black background and fluorescent colors paint a vivid picture
  • The low-profile of the lid allows it to fit into seriously tight quarters
  • The corners of the tank are sealed with silicone to prevent leaks
  • The QuietFlow filtration system is highly effective and very quiet

CONS:

  • Some users reported that the lights stopped working after a while
  • We’ve seen users report some cracking issues shortly upon delivery

Advantages of Owning a Nano Aquarium

  • Cheaper to Run – Most nano aquariums tend to come as a complete kit that includes its own filter, light bulbs, and pumps. Some of them even come with fish food. This reduces your overall equipment costs and makes them more manageable. Further, a smaller tank means fewer means of decoration, pumps, and light fixtures.
  • Space-Saving – The definition of nano is one billionth of something, which gives you an idea of how small these aquariums are. This makes it easier for you to find room for one almost anywhere in your house.
  • Low Maintenance – Obviously, a small-scale aquarium will be a lot easier to maintain in comparison with a larger model. You’ll also find that doing regular water changes isn’t a hassle with nano aquariums and doesn’t take too much time.
  • Lightweight – One of the reasons why people don’t want to deal with large aquariums is their weight. Well, nano aquariums are relatively light compared to a 100-gallon tank. In addition, larger aquariums require a sturdy aquarium stand to handle their weight. Which is something that a nano aquarium won’t need as it can be placed anywhere.

Disadvantages of Owning a Nano Aquarium

  • Unstable Salinity – Nano aquariums have lesser water volumes which result in a less stable level of salinity and nutrients in the water. Also, smaller volumes change quality and chemistry a lot faster than larger volumes. To maintain a good level of salinity, the water needs to be topped off on a regular basis. Which can get very tedious after a while.
  • Limited Fish Options – Due to limited space, you’ll obviously face some restrictions as far as the number of fish you can put in your aquarium. Whether you use it as a saltwater or freshwater nano tank. You’ll have to consider the size, temperament, and compatibility of the fish you’re going to put in it.

Glass vs Acrylic Nano Aquariums

Most nano aquariums are either made of glass or acrylic. To ensure the best bang for your buck, you must consider the advantages and disadvantages of each type.

Advantages of Glass Aquariums:

  • Harder to scratch than acrylic
  • The distortions are less visible
  • A lot more available than acrylic
  • Maintains its clarity over time
  • Easier to find accessories for them

Disadvantages of Glass Aquariums:

  • It’s hard to fix when scratched
  • Much heavier than acrylic
  • It’s available in limited shapes
  • Not as durable as acrylic tanks
  • They’re harder to drill into

Advantages of Acrylic Aquariums:

  • Lightweight and easily portable
  • Available in a variety of shapes
  • A lot harder to break than glass
  • Easy to re-polish and refinish
  • A lot easier to drill into than glass

Disadvantages of Acrylic Aquariums:

  • A lot easier to scratch than glass
  • Tends to get discolored over time
  • They’re usually most expensive
  • The base tends to be weaker
  • Hard to find accessories for them
