Classic 6ft x 18" x 18" Aquarium

Aquariums Brisbane “Classic Aquarium”

(Length x Width x Height) 6ft x 18″ x 18″ Aquarium - 1830mm x 450mm x 450mm

Designed and handcrafted in our Brisbane workshop, the Classic range brings together years of practical fishkeeping experience with proven aquarium construction methods. Whether you’re setting up your first aquarium or you’ve been in the hobby for decades, the Classic range provides a strong, dependable foundation for your next setup.

Every aquarium is constructed using brand new glass and high-quality, purpose-specific silicone. Glass thickness is selected in accordance with our established safety factor standards, with every aquarium designed to meet or exceed our minimum safety factor for long-term strength, reliability and peace of mind.

Full top cross-bracing is incorporated for structural support, with bridges positioned at a minimum of every 600mm where required. Two-part sliding glass lids are included as standard and thoughtfully notched at the rear corners, allowing practical access for filtration pipework, hoses, electrical cords and equipment.

There are no unnecessary gimmicks and no shortcuts hidden behind the glass — just a well-thought-out aquarium built by people who understand how aquariums are actually used.

Built right here in Brisbane, Australia.

With a large selection of popular Classic Aquarium sizes readily available from our workshop, your next aquarium is already waiting for you.

This Aquarium –

A long display aquarium (approx. 370 litres) provides an impressive 6-foot (180cm) swimming length while keeping the width, depth, and overall volume manageable. This balance makes it a fantastic choice for showcasing active schooling fish, while remaining practical when it comes to equipment, running costs, and maintenance.

Freshwater

• Medium to Large schools of tetras, rasboras, danios, or rainbowfish
• Mid-sized cichlids (angelfish, keyholes, dwarf cichlids, discus)
• African cichlids
• Gouramis (pearl, dwarf, honey)
• Bottom dwellers such as Corydoras, loaches & small catfish
• Plecos (bristlenose or smaller species)
• Community fish like livebearers, barbs.

Saltwater (with proper equipment & setup)

• Clownfish pairs or small groups
• Gobies, blennies, firefish & smaller wrasses
• Dwarf angelfish
• Reef-safe invertebrates (shrimp, hermits, snails)
• Great layout potential for long reef structures, soft corals, LPS & SPS (for experienced keepers)

The length creates a striking panoramic effect and plenty of open water for active species, while the moderate width and height keep the tank accessible, easy to maintain, and cost-effective compared to deeper, bulkier aquariums. An excellent choice for aquarists wanting the drama of a 6-foot display without the challenges of a full extra-wide tank. We also think size suits fish rooms where aquariums are stacked in racks, they are a great size for grow out tanks.

All of our classic aquariums come with a styrofoam foam base to suit.
