UNS tanks also feature deeper dimensions that follow the golden rule more closely than competing brands. UNS aquariums and paludariums also come with a black nano-foam leveling mat, ensuring your aquarium has proper cushioning on your desk, table, or where ever you decide to hold your underwater masterpiece.
