1. What type of livestock is ideal for a 2.9-gallon nano aquarium?
Due to its compact 2.9-gallon volume, the UNS 3N is best suited for low-bioload nano aquascapes. It also makes an exceptional desktop display for aquatic mosses and slow-growing epiphytic plants like Anubias Nana Petite.
2. Why is a leveling mat necessary for rimless nano aquariums?
Because rimless glass tanks rest directly on their bottom panel without a raised plastic perimeter frame, even microscopic debris or grain of sand on a stand can create concentrated stress points. The included dense foam mat absorbs vibrations and distributes weight evenly across the entire footprint to prevent glass fractures.
3. Can I use a glass lid on the tank?
Yes. Ultum Nature Systems offers precision-cut glass lids (available in Lid + Clip or Flush Fit options) to minimize evaporation and prevent livestock from jumping out.
