Ultum Nature Systems Ultra Clear Rimless Aquarium - Low Iron Glass Fish Tank with 45° Mitered Edges, 5mm-12mm Thick, Leveling Mat Included (3N, Nano, 3 Gallon)

...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.

I was looking for a simple tank, something that didn't include a filter or pump since I already had one, and I came across Ultum while searching on Amazon! I bought the 2.9 gallon tank and I LOVE it. The view is breathtaking and I can always see my betta! I believe I could only fill approximately 2.5 gallons, otherwise water would roll over. If I wanted a bigger tank, I would definitely buy from Ultum!Shipping: Bought it on Friday morning, arrived by Wednesday night in 2-3 layers of bubble-wrap!Foam on the bottom is not directly attached/glued, hence easy removal!

Love it. Fun little tank. May be slightly less than 3 gallons, but looks great.

Beautiful tank! Setup a 3 gallon nano tank for my Betta. Glass is super clear and construction is amazing.UPDATE: Tank developed a leak somewhere after 4 months of use, i way outside of my return window. Came home to water pooled all around the tank, i will try to reach out to the manufacturer to see if there is any resolution here.

5 stars if it had a cover and if it was cheaper. Very nice betta fish tank though. I added a plant and a sponge filter and betta has still horizontal room to swim.
