UNS Rimless Nano Glass Aquarium Tank

Ultum Nature Systems nano aquariums offer a compact, focused approach to aquascaping. Featuring the original UNS 3N and 5N, these tanks have become well-loved for their unique proportions and the level of detail they encourage at a smaller scale.

Their compact size challenges aquascapers to create layouts with intention, where attention to detail on every aspect: from aquatic plant selection, hardscape placement, and final composition, is highlighted in the provided space. They’ve also become some of our personal favorite aquariums since they make it easy to experiment and rework layouts. We’ve done countless rescapes in these tanks over time!

Nano aquariums are lovely for maintaining smaller planted setups. They’re easy to maintain, fit comfortably into a variety of spaces, and are almost a special rite of passage in the aquarium hobby. Whether gifted as a first aquarium or a dedicated micro design, the 3N and 5N provide a rewarding way to aquascape at a small, but mighty scale.

Like all UNS aquariums, each tank is crafted with ultra-clear low iron glass and clean, minimalist lines, offering a refined foundation for your next freshwater planted or saltwater reef aquarium.
