Ultum Nature Systems tall rimless aquariums emphasize height and vertical composition, offering a unique format for aquascaping with upward movement and structure. Their increase height allows for taller aquatic plants, and dynamic hardscape that extends above the water’s surface.
This type of tank works especially well for layouts that focus on vertical growth, including jungle-style aquascapes or forest-inspired layouts. Smaller sizes are fantastic canvases for Wabi Kusa or single plant displays.
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.

Reviews
Gorgeous
"This is my first UNS tank. It's immaculate, the blue background is very pretty and well bonded to the glass. Arrived well packaged and safe. Seams are beautiful. I bought it to build a bookshelf terrarium for my Blue Death Feigning Beetles. Glass Aqua has always been a reliable place to get quality products. If you're on the fence, get it :)"
It’s a great tank
"This was my first UNS tank. I’ve seen the tanks in- person so I knew exactly what to expect. This was my first time ordering a tank online. I was hesitant to do so but was very happily surprised to open a well packed and protected aquarium. The package was shipped in a double-layered cardboard box with styrofoam padding along each side, and delivery went off without a hitch! I’m excited to order from Glass Aqua in the future"
UNS 60 limited edition
"First id like to mention how well the tank was packed, thank glass aqua for insuring it arrived safe. The tank itself is pretty nice, I could argue it isn't worth the extra money and you could just put a blue background on a regular 60u but I'm very happy with it. No extra work once you get it home."
Beautiful aquarium
"I bought the 60S for an iwagumi project I’ve been planning. The tank is perfectly constructed and the mitered corners are an elegant detail. The glass is flawless. I can’t wait to get this project started."
"This was mothing like what i ordered. I got a tiny little tank with a lid that barely cover half the tank. It was supposed to be a 40 gallon tank with a glass lid. It was maybe a 2 gallon. It was definitely not what i ordered."
Great product
"I purchased the UNS 40C for a bioactive terrarium to house my pet millipede, and I couldn't be happier with it. The tank is exceptionally well built, with sturdy construction and a beautifully minimalist design. The glass is crystal clear, and its thickness gives the aquarium a premium, high-quality feel while providing confidence in its durability. It truly elevates the entire display and makes the terrarium look like a showcase piece. Highly recommended if you're looking for a rimless tank with outstanding craftsmanship."
"Love it"
Great aquarium.
"Beautiful glass aquarium, working on landscaping it and then adding my snails, shrimp, and fish to it after I get it all setup but it looks awesome."
Excellent fish tank
"I really like my shallow fish tank. I recently bought a betta fish and my fish really likes his tank. The tank is super secure and made of crispy clear, high quality pieces of glass"
