1. What is the UNS 20C nano cube best used for?
Due to its 2.1-gallon volume and compact 7.87" dimensions, the UNS 20C is ideal for micro-aquascaping, tabletop displays, moss arrangements, or small colonies of ornamental dwarf shrimp and pest snails.
2. Can I keep fish in a 2.1-gallon aquarium?
Due to the small 2.1-gallon volume, most fish are not recommended as water parameters fluctuate rapidly in nano environments.
3. Why is a leveling mat necessary for rimless aquariums?
Because rimless glass tanks rest directly on their base panel without a raised plastic frame, even a microscopic grain of sand on a stand can create concentrated stress points under weight. The included dense foam mat absorbs micro-vibrations and distributes weight evenly across the entire footprint to prevent glass stress cracks.

"good quality products, and quick delivery 👍"
"Fast shipping, and it came in one piece."
"At the behest of a self proclaimed "tank nerd" I purchased teh aquarium setup to house some shrimp and a few fish. He was extremely happy with what was received, and I did like the apparent quality of what was received. Only issue was the address was "corrected" to a completely different one. Fortunately it was "corrected" to another facility w/in our company. I would prefer that the address suppliede was the one used. I put what I meant and I meant what I put."
"Great little tank!"
"Great packaging quick shipping. This is my 5th UNS tank and they are beautiful. The 20c has alot of creative options whether going terrarium or aquascape. I'm ordering a Aqua Worx sol puck light to pair with it."

"I was just skimming though the web when the idea of aquascaping caught my attention. I immediately started researching all about aquascapes and started my very own from the help of this website. I knew that I really wanted a nice rimless tank. The image was what caught my eye."
