A nano tank, in essence, is a compact aquarium designed to house a small yet vibrant aquatic community. Typically, these tanks hold anywhere from 2 to 10 gallons of water, making them perfect for those with limited space or seeking a more manageable ecosystem.

Now, you might ask yourself, “Why opt for a nano tank?” The answer is simple: their charm lies in their size. These tiny havens provide a unique opportunity to showcase stunning, intricate aquascapes and create a captivating environment for small aquatic species. Moreover, they demand less maintenance than their larger counterparts without compromising beauty or diversity.

But don’t be fooled by their modest dimensions! Nano tanks can still accommodate a surprising variety of flora and fauna, offering endless possibilities for creative aquascaping. From verdant carpets of moss to delicate corals and from petite shrimp to vividly colored fish, these tanks are nothing short of mesmerizing.

To summarize, nano tanks are compact, customizable, and captivating. They bring the allure of the underwater world to any space, however small it may be. So, if you’re eager to dive into the world of aquascaping, a nano tank might just be the perfect starting point.

What to consider when looking for a nano aquarium?

As we dive into our buying guide for nano aquariums, we must consider various factors to ensure you choose the perfect tank. After all, creating a thriving aquatic environment goes beyond just the size of the tank. The following sections will explore key aspects such as materials, shapes, kits, water type, location, and suitable species for your nano aquarium.

By carefully examining these considerations, you’ll be well-equipped to make an informed decision, setting the stage for a stunning and thriving underwater world in your very own home. So, let’s begin our exploration of the essential factors to remember when choosing the ideal nano tank for your aquatic friends.


When selecting a nano aquarium, the material plays a significant role in the tank’s durability, appearance, and overall functionality. There are three primary options: glass, acrylic, and plastic

Let’s take a closer look at each of these materials.


Glass is a traditional and popular choice for aquariums. It offers excellent clarity, allowing you to observe your aquatic inhabitants easily. Glass is also scratch-resistant, meaning your tank is less likely to show wear and tear over time. However, glass tanks are heavier and more fragile, making them prone to breakage if not handled carefully.


Acrylic tanks are another option for aquarists. These tanks are lightweight and stronger than glass, reducing the risk of breakage. They also provide a seamless appearance, as their seams are nearly invisible. Acrylic can be molded into various shapes, offering more design options. However, acrylic tanks are more susceptible to scratching and may become discolored when exposed to sunlight.


Plastic tanks are an affordable and lightweight option for those new to the hobby or looking for a low-maintenance choice. These tanks are widely available in a variety of shapes and sizes. However, plastic tanks offer less clarity compared to glass and acrylic tanks, which may affect the overall visual appeal.

GlassHigh clarity, scratch-resistant, affordableHeavy, fragile, visible seams
AcrylicLightweight, strong, seamless appearanceProne to scratching, can discolor, costly
PlasticLightweight, affordable, variety of optionsLower clarity, less durable than glass


The shape of your nano aquarium is another important aspect to consider, as it can influence your tank’s overall aesthetic appeal and functionality. Here, we’ll discuss five common shapes: cubes, rectangles, bowls, bowfront, and cylinders.


Cube-shaped nano tanks offer a modern and stylish look. Their symmetrical design allows for even distribution of light and easy aquascaping, making them a popular choice among aquarists.


Rectangle-shaped tanks are a classic choice, offering more horizontal space for aquatic inhabitants to swim and explore. This shape also provides ample room for various plants and decorations.


Bowl-shaped nano aquariums create a unique and visually striking display. Their curved design allows for a 360-degree view of your aquatic environment. However, their rounded shape may limit your fish’s available swimming space.


Bowfront tanks feature a curved front panel, adding a touch of elegance and depth to your aquarium setup. This shape provides an enhanced viewing experience and additional swimming space for your fish.


Cylinder-shaped tanks create a captivating, pillar-like display. They allow for a 360-degree view of the aquarium but may require specialized equipment and creative aquascaping due to their unique shape.

CubeModern, even light distribution, easy aquascapingLimited horizontal swimming space
RectangleClassic, ample swimming and aquascaping spaceLess visually striking than other shapes
BowlUnique, 360-degree viewLimited swimming space, aquascaping challenges
BowfrontElegant, enhanced viewing, extra swimming spaceMay require more space than other nano tanks
CylinderCaptivating, 360-degree viewSpecialized equipment, aquascaping challenges


For those venturing into the world of nano aquariums, kits can be an attractive option. These all-in-one aquariums typically include the tank itself and essential equipment, such as filters for small aquariums, heaters, and lighting systems, streamlining the setup process. So, what are the benefits and drawbacks of choosing a kit?

One of the most significant advantages of opting for a kit is convenience. Packaging all the necessary components saves time, effort, and, often, money. Moreover, compatibility issues are virtually eliminated because the equipment is designed to work seamlessly with the tank.

However, it’s important to note that kits may have some limitations. For instance, the included equipment might only sometimes be of the highest quality, or it may not cater to your specific needs or preferences. Additionally, more experienced aquarists may already possess certain components, making some kit elements redundant.

Type of Water: Freshwater or Saltwater

Another crucial decision when setting up your nano aquarium is whether to create a freshwater or saltwater environment. Both options come with their unique challenges and rewards, so let’s delve into the key differences between them.

Freshwater aquariums tend to be more beginner-friendly, with a simpler setup process and lower maintenance requirements. The vast array of freshwater fish species available means you’ll have plenty of choices when selecting your aquatic friends. Moreover, many freshwater plants are relatively easy to care for, which can be a major draw for those new to the hobby.

In contrast, saltwater aquariums are often considered more complex and demanding. They require specific water conditions and careful attention to parameters such as salinity and pH levels. That said, saltwater tanks boast a dazzling array of colorful fish, corals, and invertebrates, which can make the extra effort worthwhile for many enthusiasts. Additionally, the unique challenges of maintaining a saltwater tank can be an appealing learning experience for those looking to expand their aquarist knowledge.

The choice between a freshwater or saltwater nano aquarium will largely depend on your experience, desired level of involvement, and the species you wish to keep. Freshwater tanks are an excellent option for beginners or those seeking a more manageable setup. In contrast, saltwater tanks cater to those passionate about creating a vibrant, diverse underwater ecosystem and willing to invest the time and effort required.


Choosing the perfect spot for your nano aquarium can be a critical aspect of ensuring its success and longevity. Finding the right balance between aesthetics and practicality is key, and there are several factors to consider when determining the ideal location for your tank.

First and foremost, consider the weight of the filled aquarium. Even a small nano tank can be surprisingly heavy once filled with water, substrate, and decorations. Therefore, selecting a sturdy, level surface that can safely support the tank’s weight is essential.

Next, think about the availability of power outlets. Your aquarium will require various equipment, such as filters, heaters, and lighting, so having easy access to electricity is crucial. Avoid placing your tank where cords will be stretched or tangled, as this can create a safety hazard.

Lighting is another crucial factor. While natural light can be beneficial for your aquarium, excessive direct sunlight may lead to rapid algae growth and overheating, which can be detrimental to your aquatic inhabitants. Aim to place your tank in an area that receives indirect sunlight or has adjustable lighting options.

Lastly, consider the overall ambiance of the location. Your nano aquarium should be in a calm, low-traffic area where sudden movements or loud noises won’t stress your fish. Additionally, positioning your tank where it can be easily admired and enjoyed will add to the satisfaction of your aquascaping efforts.

Choosing the Right Species for Your Nano Aquarium

When it comes to selecting the right species for your nano aquarium, there are several factors to consider. The type of water (freshwater or saltwater), compatibility with other species, size, and temperament of the fish are all crucial aspects to keep in mind. Here, we’ll discuss some guidelines to follow when choosing your fish and provide a list of suitable species for a nano tank.

What to consider

  1. Size: Choose fish that will remain small even when fully grown, as larger fish may struggle in the limited space of a nano tank.
  2. Temperament: Opt for peaceful, community-oriented species that will coexist harmoniously with other fish and invertebrates in the tank.
  3. Activity level: Consider fish that are active swimmers but not overly boisterous, as overly active fish may stress other inhabitants.
  4. Care requirements: Select fish that have similar water parameter needs and care requirements to ensure a stable and healthy environment.
  5. Breeding habits: Be aware of the breeding habits of your chosen species, as some fish may reproduce rapidly, leading to overcrowding in a small tank.

List of good fish for a nano tank



  • Clown Goby (Gobiodon spp.)
  • Neon Goby (Elacatinus spp.)
  • Green Clown Goby (Gobiodon atrangulatus)
  • Firefish Goby (Nemateleotris magnifica)
  • Royal Gramma (Gramma loreto)
  • Sexy Shrimp (Thor amboinensis)

By considering these guidelines and selecting appropriate species for your nano aquarium, you can create a harmonious, healthy environment that showcases the beauty and diversity of the aquatic world.


How many fish can you put in a nano tank?

The number of fish you can put in a nano tank depends on the tank’s size and the specific fish species. A general rule is to have one inch of fish per gallon of water, but it’s essential to research the specific needs and compatibility of the species you choose.

Is a nano tank hard to maintain?

Nano tanks can require some attention due to their small size, as water parameters can change rapidly. However, they can be manageable even for beginners with proper planning, regular maintenance, and careful monitoring.

What is the smallest fish for nano tank?

The Scarlet Badis (Dario dario) is one of the smallest freshwater fish suitable for nano tanks, growing up to just under an inch in size. In saltwater tanks, the Green Clown Goby (Gobiodon atrangulatus) is a tiny species, reaching around 1.5 inches in length.

Do nano tanks need air pump?

Nano tanks may not always require an air pump if sufficient surface agitation from the filter provides adequate oxygen exchange. However, an air pump can be beneficial in ensuring proper oxygen levels, especially in densely stocked or heavily planted tanks.

Do nano tanks need a heater?

Whether a nano tank needs a heater depends on the specific temperature requirements of the fish and plants you plan to keep. If your chosen species require stable, warm water conditions, a heater will be necessary to maintain the appropriate temperature.
