Ultum Nature Systems standard rimless aquariums offer an elevated take on traditional tank formats, supporting a wide range of aquascaping styles. With subtle adjustments to classic proportions, UNS standard tanks provide a versatile canvas for building complete aquascape layouts with signature foreground, midground, and background composition.

This format is great for nature-style planted aquariums, allowing for flexibility in plant selection, hardscape structure, and overall layout design. From simple aquascapes to contest-ready displays, standard aquariums make it easy to try different nooks within the hobby. The UNS 60U has become a go-to size for many aquascapers, offering a balanced footprint that’s manageable to maintain while still providing enough space to create beautiful planted tanks.

Available in a variety of sizes, standard aquariums remain a pillar for hobbyists looking for a well-rounded, adaptable tank that balances design, form and function.

UNS Rimless Standard Glass Aquarium Tank $104.99

Scapelight - The Standard Form

In aquarium terms, “standard” refers to a proportionally balanced, rectangular tank with more than 9 gallons of total water volume. This category includes some of the largest aquariums that modern-day hobbyists can fit into their homes! They’re a pillar of the aquarium hobby—they’re easy to maintain and balance thanks to their physical space and water volume. Some of our favorites (and best-selling sizes) include the Ultum Nature Systems 45U (9-gallon) and 60U (20-gallon) rimless tanks. Let’s highlight past planted tanks in each of these classics.

UNS 45U

9.3 GALLONS

Green Haven

This nature-style planted tank came to life in the UNS 45U standard rimless glass aquarium. The main star was carefully selected Malaysian Driftwood that would influence every decision made afterwards. Teetering between a centered and triangular layout, this aquascape remains in our personal top favorites. (We think the scape community might agree!) We completed the look with focus on the fine details. Everything from moss-covered wood and epiphytic aquarium plant placement to supporting stones, accent gravel, and equipment was chosen with care and intention.

Tank Dimensions: 17.71 x 11.02 x 11.02”
Plants Used: Rotala sp., Bolbitis Heudelotti, Peacock Moss, Mixed Bucephalandra sp.
Hardscape: Malaysian Driftwood, Manten Stone
Substrate: Tropica Aquasoil, Natural Sand & Gravel

UNS 60U

20.5 GALLONS

Green Glacier

On the opposite end of the spectrum, Green Glacier is an Iwagumi aquascape that features heavy Seiryu Stone work in the 20-gallon Ultum Nature Systems 60U aquarium. The UNS 60U is our go-to recommendation for a standard-sized planted tank—and a best-seller at that. It’s well-balanced: not small enough to be considered a nano aquarium, yet big enough to comfortably support a sizable school of tropical fish like Tetras or Rasboras. This aquascape is a great example of fully utilizing the UNS 60U’s spacious dimensions, with high sloping substrate topped off with one of our favorite aquarium carpeting plants, Micranthemum ‘Monte Carlo’.

Tank Dimensions:23.62 x 14.17 x 14.17”
Plants Used: Micranthemum ‘Monte Carlo’
Hardscape: Seiryu Stone
Substrate: UNS Controsoil, UNS Controbase

Together, these aquascapes highlight the versatility of Ultum Nature Systems Standard Rimless Aquariums. From intricate woodwork to dynamic stone layouts, a standard tank can support it all. What will you create next?

Reviews

Nice tank

"Shipping was good and tank came in one piece. Can definitely tell the difference in quality compared to cheaper alternatives."

— Lindsey (5/5)

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 :)"

— Kyla F. (5/5)

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"

— Michelle S. (5/5)

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."

— David Z. (5/5)

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."

— Keith D. (5/5)

"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."

— Debby (1/5)

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."

— Yeongji J. (5/5)

"Love it"

— Aisha (5/5)

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."

— Darin E. (5/5)

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"

— Janet L. (5/5)

Q&A

Can these tanks be drilled? Or are they constructed with tempered glass?: Yes, they can be drilled. UNS utilizes non-tempered glass for these tanks.
Would you recommend the 60U model for a Landen 23.6" W × 15.7" D × 15.7" H (60cm x 40cm x 40cm) 8mm Thickness?: Hi Malone, The UNS 60U has the following dimensions: 23.62" x 14.17" x 14.17" It's one of the most popular (one of our favorites too!) and we're certain you'll love it. Feel free to let us know if you have any additional questions.
Hi I'm looking for an aquarium stand or cabinet 45x45x85-95cm height. Do you have any?: Hello and thanks for your interest. Unfortunately we do not offer a 45CM stand since that is not a standardize aquarium size at the moment.
