Beautiful aquarium

"I got this to make my first aquascape: its sturdy, beautiful, and sleep. The mitered edge looks gorgeous and the clarity is superb."

— Nicholas B. (5/5)

UNS 45 U

"This tank is wonderful. It looks great and it comes with a mat. My only issue with the tank is that there was a small scratch but nothing major and barely even noticeable."

— Quinn M. (5/5)

Comfortable prices and shipping! Great selection of plants! List goes on…

"Hi! My name is Pablo I live in NY I recently got into the fish keeping hobby I mostly do bettas. I got my third betta may 18 of this year 2026. I came across glass aqua after trying to find a couple of plants for my 3 gallon UNS long tank that I also purchased from Glass aqua. I was originally looking at Bruce plants but no hate to them most of their collection is out of stock and I find more of a variety on glass aqua other than Bruce plants. I mean, I’m talking about soils, an extremely great selection of plants especially for beginners like me. My shipment is also fast which I extremely love since I am an impatient guy. For something to be shipped to California and arrive to your door across the United States in NY in less than a week. That’s extremely impressive! I am most likely to recommend glass aqua to others and I’m definitely coming back."

— Pablo M. (5/5)

UNS tanks are the best

"UNS tanks are the best, glass is great, sizes are always great, never had a leak (I have 3 of them, all different sizes), & glass aqua has the fastest shipping for the UNS brand tanks which are already fairly hard to find."

— Kelsie F. (5/5)

"It came very fast love the tank looks very nice"

"Stocked up quickly after selling out Memorial Day."

Sleek, high quality tank with great clarity

"I’m really impressed with this UNS rimless tall glass aquarium. The glass clarity is excellent—super clean, no distortion, and really makes everything inside pop. The rimless design gives it a modern, minimalist look that fits perfectly in any space. The build quality feels solid, with clean silicone work and sturdy construction. I especially like the tall profile—it’s great for aquascaping and creating depth. Only thing to keep in mind is that because it’s rimless, you’ll want to be careful during setup and maintenance, but that’s expected with this style of tank. Overall, definitely worth it if you’re looking for a clean, high-end aquarium."

— Teagan R. (5/5)

— Christopher P. (5/5)

"came fast and just as expected"
