Aquascaping Essentials Ultra Clear Rimless Cube Aquarium – 27L (30x30x30cm, 5mm Glass)

The 30cm cube is the size most aquascapers reach for first. It is large enough to build a proper layout with depth and a real focal point, yet small enough to sit on a desk, sideboard or shelf without dominating the room. At 27 litres it gives you room to plant, scape and stock a small community, while staying easy to maintain and quick to water-change.

Where this cube earns its place is the glass. We use ultra-clear, low-iron glass. Standard aquarium glass carries a faint green tint that mutes plant colour and dulls hardscape; low-iron removes it, so reds read as red and your scape looks the way it does in your head rather than through a bottle. The rimless build with precision-polished, mitred edges means no plastic bracing breaking the view from any angle, and a clean seam line that holds up to an algae scraper run into the corners.

It is a genuinely versatile footprint. The cube shape suits island and Iwagumi layouts, a single nature-style focal stone, or a lush jungle scape, and it works equally well as a planted betta home or a desktop Wabi-Kusa. Pair it with a clip-on nano light and a small filter and you have a complete display in a footprint smaller than an A4 sheet.

What fits in a 27L cube

• Betta: a single betta with gentle filtration and planting.
• Nano fish: a small school of one species such as Chili Rasbora, Celestial Pearl Danio or Ember Tetra, once fully cycled and well planted.
• Planted or hardscape only: Iwagumi, Wabi-Kusa, moss and bonsai-style scapes.

A cube this size is not suited to goldfish, cichlids, or larger community fish. If that is your plan, look at our 40cm cube or a longer footprint instead.
