Allcolor Artisan Grade Ultra Clear Rimless Aquarium Tank 4.6 Gallon Review (2026)

Who the Artisan Grade 4.6 gallon tank is for

This tank is built for an aquascaper who wants a small, display-focused rimless tank with a more refined finish than the brand's standard grade line, suited to a desk, shelf or entryway where the tank itself is part of the decor. The roughly cube-shaped footprint sits between a tiny 3 gallon nano and a full 10 gallon tank, giving more stocking and layout room than the smallest nanos while staying compact. It fits a hobbyist who already plans to source their own filter, light and stand, since the tank ships as bare glass. It is a weaker choice for someone wanting standard-size accessories off the shelf, since the 4.6 gallon cube does not match common lid or background sizes.

Glass, seams and dimensions

The tank measures about 10.24 by 10.24 by 10.24 inches, a near-perfect cube, with 5mm thick ultra clear low iron glass. As the brand's Artisan Grade line, the maker markets this model with a more refined seam finish than Allcolor's standard grade tanks, aimed at buyers who want the cleanest possible glass-to-glass joints for a photo-ready display. The rimless design has no frame or brace across the top, keeping the sightline unbroken from any angle, which is the main draw of this style of tank for aquascaping compared with framed aquariums.

Setting up and living with a cube-shaped nano

A cube shape like this one gives a taller water column relative to its footprint than a standard rectangular tank of similar volume, which changes how light spreads down through the water and how plants and hardscape are composed within it. Because the volume is a less common 4.6 gallons, off-the-shelf lids, background film and some canopy lights sized for round-number tanks may not fit cleanly, so measuring before buying accessories is worth the extra step. Like other rimless tanks in this guide, the open top means faster evaporation than a lidded kit, so plan on topping off with treated water several times a week.

How it compares with other rimless tanks

Against its own larger sibling, the Allcolor 10 gallon standard grade tank, this 4.6 gallon Artisan model trades volume for a smaller footprint and the brand's more refined seam finish. Compared with the Allcolor Artisan 15 gallon, which scores higher in the same guide, this cube gives up display scale but keeps the same finish quality in a size better suited to tight spaces. Against the Lifegard Aquatics and other low iron rivals in this guide, the deciding factor is mostly finish and exact footprint rather than a clear gap in glass quality, since all are ultra clear low iron rimless builds.

Verdict and who should size up or down

The Allcolor Artisan Grade 4.6 gallon tank earns a score of 8 out of 10 in this guide, reflecting a well-built small rimless option let down slightly by its odd volume and the evaporation that comes with any open-top design. It is a strong pick for a hobbyist who wants a compact, photo-ready cube for a desk aquascape and does not mind sourcing standard-size accessories carefully. Anyone wanting a bigger canvas for more elaborate hardscaping should look at the 10 or 15 gallon Allcolor tanks instead, and anyone on a tighter budget who does not need the Artisan finish can save money with the brand's standard grade line.
