Nano Aquariums & Small Fish Tanks

Discover nano aquariums and small fish tanks for compact freshwater setups, planted aquariums, shrimp tanks and aquascapes at Aquaholics. Our range includes traditional glass aquariums, premium low-iron glass tanks, acrylic nano aquariums and compact aquarium kits with selected equipment included.

Nano aquariums are ideal when space is limited, but choosing the right tank and equipment is still important. Aquaholics stocks compact aquarium options for beginners, experienced aquascapers and anyone looking to create a smaller feature aquarium at home or in the office.

What Is a Nano Aquarium?

A nano aquarium is a compact fish tank designed for smaller-scale freshwater or planted setups. There is no single official volume that defines a nano aquarium, but the term is generally used for smaller tanks that occupy considerably less space than traditional 2ft, 3ft or larger aquarium systems.

The smaller footprint makes nano tanks particularly popular for shrimp, aquatic plants and carefully selected small freshwater species. However, livestock should always be chosen according to the aquarium's actual volume, dimensions and swimming space rather than simply because a species is described as small.

Glass, Low-Iron & Acrylic Nano Aquariums

Our nano aquarium range includes several different construction styles, allowing you to choose a tank that suits your setup, style and budget.

Glass Nano Aquariums

Traditional glass aquariums are durable, scratch resistant and widely used for freshwater setups. Compact glass tanks are an excellent choice for planted aquariums, shrimp and smaller display tanks.

Low-Iron Glass Aquariums

Low-iron glass contains less iron than standard aquarium glass, reducing the green tint that can be visible through glass panels. This provides greater visual clarity and makes low-iron nano aquariums particularly attractive for aquascaping and planted displays.

Acrylic Nano Aquariums

Acrylic aquariums are lightweight and can be manufactured in shapes that are difficult to achieve with traditional glass. Acrylic is also highly impact resistant, although it can scratch more easily than glass and should be cleaned with suitable aquarium-safe tools.

Nano Aquariums for Aquascaping

Small aquariums are extremely popular for aquascaping because even a relatively compact space can be transformed using carefully selected plants, rock, wood and substrate.

When creating a nano aquascape, scale becomes particularly important. Smaller-leaved plants, appropriately sized hardscape and carefully positioned focal points can make a compact aquarium appear much larger and more detailed.

Explore our aquascaping supplies, including aquarium rock, wood, planted substrates, tools and water supplements for creating your nano aquascape.

Nano Aquariums for Shrimp

Nano aquariums can be an excellent option for freshwater shrimp when correctly established and maintained. A planted shrimp tank can provide grazing surfaces, cover and an attractive natural display while requiring relatively little physical space.

Choosing Equipment for a Nano Aquarium

Although nano tanks are smaller, they still require appropriate filtration, lighting and, for tropical setups, temperature control. Equipment should be selected according to the aquarium's actual water volume and the livestock or plants you intend to keep.

• Aquarium filtration – choose appropriately sized filtration with suitable flow for a smaller aquarium.
• Aquarium LED lighting – select lighting according to the tank dimensions and the requirements of your aquarium plants.
• Nano aquarium heaters – compact heating options for appropriately sized tropical aquariums.
• Aquarium substrate, gravel and sand – choose decorative or planted substrates to suit the style of your nano tank.
• Live aquarium plants – create a natural planted nano aquarium with suitable aquatic plants.

Are Nano Aquariums Easier to Maintain?

A smaller aquarium does not necessarily mean an easier aquarium. Because nano tanks contain less water, changes in temperature and water chemistry can occur more quickly than in a larger aquarium.

Regular maintenance, sensible stocking, appropriate filtration and consistent water changes are therefore especially important. Avoid overstocking and introduce livestock only after the aquarium has been properly established and cycled.

Complete Nano Aquarium Kits

Complete nano aquarium kits can provide a convenient starting point because selected equipment such as filtration or lighting may already be included with the aquarium.

What is supplied varies between models, so always check the individual product description before purchasing. Additional equipment such as a heater, lighting upgrade, substrate or water treatments may still be required depending on the aquarium you want to create.

Frequently Asked Questions

What size is considered a nano aquarium?

There is no single officially defined volume for a nano aquarium. The term generally describes compact aquariums that are substantially smaller than traditional full-size fish tanks. Always use the actual dimensions and water capacity when deciding whether a tank is suitable for particular livestock.

Are nano aquariums suitable for beginners?

They can be, but smaller aquariums are not automatically easier to maintain. Their lower water volume means changes in temperature and water chemistry can occur more quickly, so regular maintenance and sensible stocking are important.

Can I keep fish in a nano aquarium?

Some small freshwater species may be suitable for appropriately sized nano aquariums, but suitability depends on adult size, activity level, social requirements and the dimensions of the tank. Always research the needs of a species before adding fish.

Are nano aquariums good for shrimp?

Yes. A properly established nano aquarium can make an excellent freshwater shrimp tank. Live plants, suitable filtration and stable water conditions can help create an attractive and healthy shrimp setup.

Are nano aquariums good for planted tanks?

Yes. Nano aquariums are popular for planted aquascapes. Appropriate lighting, substrate, plant selection and regular maintenance can create an impressive planted display in a relatively small space.

Do nano aquariums need a filter?

Most stocked nano aquariums benefit from appropriate biological and mechanical filtration. The filter should be matched to the aquarium volume and livestock, with particular attention to flow strength in small tanks and shrimp setups.

Can I buy a nano aquarium on the Sunshine Coast?

Yes. Aquaholics Aquarium Supplies is located in Baringa on the Sunshine Coast and stocks nano aquariums, small fish tanks and equipment for compact freshwater and planted setups.
