    • Well crafted and beautiful, it is one of my most prized pieces
Size: [45S] 5.9GAL | 22.6L
The tank came in excellent condition. I love how thick the glass is, and how light it is. I do wish there was the option of added adhesive ships for the leveling mat. Definitely worth the price, especially for a small tank.

love it, description picture made it look like more of a long and narrow rectangular tank, but it's more on the shallow square side. i was not too phased by the shape difference, it's a lovely tank and it has a very clean and sharp look to it. they packaged it well and it arrived safely and with no damage. would definitely buy again and or suggest to someone else 🙂↕️ ... show more

    • Love it
Size: [45L] 3.4GAL | 13L
This arrived well packed and insulated for shipping. I set it up and it's looking pretty great! I like the edges better than other options out there. It's a little more expensive than other dealers, but the quality is worth it.

    • What a beautiful tank
Size: [45L] 3.4GAL | 13L
There is nothing I do not like about the tank it’s came very well packaged and was fun to set up.I will only buy this tank if I decide to get another Betta (love those little fish)The rimless tanks are so beautiful this is my second one but my other one is a cube I like it but the long style I think is better for Betta’s I know they should be in a tank that is at least 5 gallons but the length is almost 18” long that is a lot of swimming space and setting it up was so much easier the the taller tanks.If you are thinking of buying a rimless tank I highly recommend this company.I will update with a picture with the new fish after the weekend tank is all set for him,One thing I would recommend is if you use the sponge filters make sure you use the nano tiny sponge filters because tank is under 7” tall,I like the water almost to the top with a cover and enough room for fish to get air and bubbles from the sponge filters I normally use bubble over.All in All Great Tank ... show more

    • I highly recommend UNS
Size: [60S] 10.2GAL | 38.8L
While I didn’t end up keeping the product since I ordered the wrong item UNS aquariums are some of the best out there. The clarity is unmatched and is such a step up from your average aquarium. The unique sizes and dimensions also add a whole new way to scape and design aquariums and terrariums. However this does come at a large increase in price! ... show more

    • Loved it so much...
Size: [3N] 3 Gal 12.2 x 7.48 x 7.48
...I had to buy 2 more tanks. They certainly are beautiful and worth the money. A new aquascaping store opened where I live and they have several brands of tanks on display (planted and with fish) the UNS tanks are a standout, not only for the clarity of glass and the 45 degree mitered corners, but the unique shapes available. The vendor for these tanks on Amazon is Substrate Source and they have been phenomenal on quality and speed of their shipping. I've ordered the UNS Contrasoil from Substrate also. ... show more

Wow. This fishtank is amazing! It was well packed and in pristine condition upon arrival. It has a bit more weight than your average fish tank you'd get from a chain pet store. The craftsmanship is obvious as soon as you take it out of the box. The glass is super clear, the silicone used to hold the glass pieces together was done with attention to detail. It Looks so clean!! I am sooooo happy. Plus the long and shallow size is perfect for my betta. He absolutely LOVES it! ❤️ p.s. I got the 17×6×6 ... show more
