5ft / 150cm Aquariums & Fish Tanks

Shop 5ft and 150cm aquariums for larger freshwater fish, planted tanks, aquascaping and impressive feature displays at Aquaholics. A 5ft aquarium provides generous swimming space and the room to create more substantial freshwater environments while making a striking feature in a home, office or dedicated fish room.

Our range includes premium low-iron glass aquariums and complete aquarium and cabinet systems. Sunshine Coast customers can also visit Aquaholics in Baringa for help selecting a tank and the filtration, lighting, heating and other equipment required to build a complete setup.

Why Choose a 5ft Aquarium?

A 5ft aquarium generally refers to a fish tank around 150cm long. The exact width, height and water capacity vary between models, and these additional dimensions can make a significant difference to both total volume and usable swimming space.

The extra length makes a 150cm aquarium an excellent option for larger freshwater displays, more active fish and ambitious planted aquariums. It also provides greater flexibility for creating defined territories, open swimming areas and larger-scale aquascapes.

Always select livestock according to adult size, activity level, social behaviour and the actual dimensions and capacity of the aquarium.

Premium Low-Iron Glass 150cm Aquariums

Our 5ft aquarium range includes premium low-iron glass systems designed to provide excellent viewing clarity.

Low-iron glass contains less iron than conventional aquarium glass, reducing the green tint that can become more noticeable through thicker glass panels. This improved clarity can make fish colours, aquatic plants and aquascaping details appear more natural, making low-iron glass particularly attractive for large feature aquariums.

Complete 5ft Aquarium Setups

A complete 5ft aquarium system can simplify the planning of a larger freshwater setup. Depending on the model, complete systems may include the aquarium, matching cabinet, LED lighting, filtration or sump components and other equipment.

Always check the individual product description to confirm exactly what is included, as specifications and supplied equipment vary between aquarium systems.

If you're looking for a particular 5ft or similarly sized aquarium and cabinet combination that isn't currently displayed online, Aquaholics can also check ordering options from leading aquarium brands including Aquael, OASE and Bioscape, subject to current model availability.

Sumped 5ft Aquarium Systems

Some larger aquarium systems use a sump located inside the cabinet beneath the main display tank. A sump can provide substantial filtration capacity while allowing equipment and filter media to be housed away from the main aquarium.

Sump configurations vary between models, so check the individual aquarium specifications carefully to understand what equipment is supplied and what additional components may be required.

5ft Aquariums for Planted Tanks & Aquascaping

A 150cm aquarium provides excellent proportions for creating a large freshwater aquascape. The additional horizontal space allows for more complex layouts using aquarium rock, wood and live plants while retaining generous open swimming areas.

Larger planted aquariums can range from relatively simple natural displays to advanced aquascapes. Lighting, substrate, fertilisation and CO2 requirements should be chosen according to the plants you intend to grow and the style of aquarium you want to create.

Explore our aquascaping supplies for aquarium rock, wood, planted substrates, tools and other products for creating your 150cm aquascape.

Choosing Equipment for a 5ft Aquarium

A large aquarium needs equipment that is correctly sized for its actual water volume, livestock and intended setup. Two aquariums that are both approximately 150cm long can have very different capacities depending on their width and height.

• Aquarium filtration – choose filtration with sufficient biological capacity and flow for the aquarium and livestock.
• 150cm aquarium LED lighting – browse lighting specifically suited to 5ft aquariums, fish displays and planted tanks.
• Aquarium heaters – select heating according to the actual water volume and temperature requirements of your setup.
• Aquarium substrate, gravel and sand – choose decorative or planted substrates for larger freshwater aquariums.
• Live aquarium plants – create natural planted displays and large-scale freshwater aquascapes.

What Fish Can Live in a 5ft Aquarium?

A 5ft aquarium can provide suitable space for a broad range of freshwater fish when stocked appropriately. The additional length can be particularly useful for larger community setups and selected active or larger freshwater species.

However, even a 150cm aquarium is not suitable for every fish. Adult size, activity level, group requirements, territorial behaviour, filtration capacity and the aquarium's actual dimensions all need to be considered before choosing livestock.

Once your aquarium is fully established and cycled, explore our range of live aquarium fish for your freshwater setup.

Setting Up a 150cm Aquarium

A 5ft aquarium becomes extremely heavy when filled with water, substrate, hardscape and equipment. The aquarium must be positioned on a strong, stable and level cabinet or stand designed to support its complete filled weight.

Install the required filtration, heating and lighting before adding substrate and hardscape. Fill the aquarium with appropriately conditioned water and allow the biological filtration system to become established before introducing fish or other livestock.
