Ultum Nature Systems rimless long aquariums are perfect for aquarium hobbyists who want extended horizontal space and panoramic views of the aquascape within. Their elongated structure encourages creative aquascaping layouts that focus on flow, depth and movement across the length of the tank.
Great for planted aquariums with nano fish, long tanks provide generous swimming space for species like tetras and rasboras who have natural schooling or shoaling behavior. Their rectangular shape, subtly lowered panels and wide profiles provide a wonderful canvas for aquascaping with enough room for unique foreground, midground, and background planting choices.
Like all UNS aquariums, each tank is crafted with ultra-clear low iron glass and clean, minimalist lines, offering a refined foundation for your next freshwater planted or saltwater reef aquarium.
