Central Aquatics offers Aqueon Frameless Glass Aquariums. The minimalist design of the aquariums helps accentuate the natural beauty of any flourishing aquatic ecosystem, the manufacturer reports. Each aquarium features polished, beveled edges for a modern design as well as smooth, clear silicone seams to keep the focus on the environment. A foam leveling mat protects both the aquarium and stand. The products are made in the USA and available in rectangle (sizes 11, 21 and 30) or cube shapes (sizes 1, 3, 6 and 14). The cube tanks also come with a bonus glass top included.
