Cube Rimless Frameless Extra Clear Glass Aquarium - Nano Cube

In this review the Cube Rimless Frameless Extra Clear All Glass Aquarium is assessed as a compact, versatile nano tank best suited for aquarists who want a clean, high-clarity display for shrimp, a single Betta, or small planted setups. The single biggest reason to buy is the tank's low-iron, extra-clear glass combined with a full-coverage lid that preserves humidity and visual clarity, making it ideal for terrariums, paludariums, and nano aquascapes.

Key Features

• Extra-clear low-iron glass: The tank uses low-iron glass to reduce green tint and deliver a noticeably clearer view of plants and inhabitants.
• Full-coverage glass lid: The included lid is the same 5mm thickness as the tank, providing a snug full cover that helps maintain a high-humidity environment and reduces evaporation.
• Rimless, frameless design: The seamless cube profile removes distracting frames and logos so focus stays on the aquascape or terrarium.
• Compact 7 gal capacity option: The 7 gal (30x30x30cm) size is large enough for a nano planted tank, shrimps, or a single Betta while remaining space efficient.
• White leveling mat included: A white leveling mat is supplied to help achieve an even base and minimize stress on the glass from uneven surfaces.

Who It's For

The Cube Rimless tank is aimed at hobbyists building small, high-clarity displays: shrimp keepers, nano planted aquascapers, paludarium or closed-terrarium creators who need a humid microclimate, and anyone who prefers a rimless aesthetic. The included full-coverage lid and low-iron glass make it particularly attractive for moss, tropical plants, and delicate microfauna that benefit from stable humidity and excellent visibility.

Those who should look elsewhere include aquarists wanting very large systems, heavy equipment mounting, or hardened commercial installations; the glass is 5mm and best suited to small, carefully set up nano tanks rather than heavy-duty public display use.
