OptiClear Cube Aquarium

OptiClear Cube Aquarium

The OptiClear Nest Cube Aquarium is purpose-built for aquascapers who want maximum clarity, perfect proportions, and a minimalist display that puts the scape first. Constructed from low-iron opti-clear glass, this cube aquarium delivers exceptional transparency and true colour viewing. Ideal for highlighting fine plant detail, hardscape texture, and depth.

Its frameless cube design creates a clean, uninterrupted viewing experience from every angle, making it perfect for planted tanks, nano aquascapes, and modern display setups. The cube format is especially popular for Iwagumi, nature-style, and high-impact nano layouts where balance and symmetry matter.

Designed to be fully customisable, the OptiClear Nest Cube allows you to choose your own lighting (Chihiros lighting recommended!!!), filtration, and aquascaping style without compromise. A removable glass lid provides easy access for trimming and maintenance, while the included foam base ensures even weight distribution and added support for the frameless construction.

Whether you’re building a statement nano aquascape or a refined planted display, the OptiClear Nest Cube is a timeless foundation.
