The UNS Limited Edition Rimless Aquarium Tank brings a fresh visual approach to the classic Ultum Nature Systems aquarium lineup. Featuring a satin-finished frosted blue background and heat-fused white bottom, this special edition series adds subtle contrast and depth while maintaining the clean, minimalist look aquascapers love.
The soft blue backdrop helps aquatic plants, hardscape, and livestock stand out naturally without overpowering the layout, while the durable white bottom creates a bright, clean foundation for aquascaping. Available in a selection of popular UNS aquarium sizes, these limited edition tanks offer the same high-quality rimless construction in a unique presentation designed for modern planted aquariums.

"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."
"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."
"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."
"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."
"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"

"I absolutely love the 17 inch cube and the lite. It’s gorgeous"
