Horizon Aquatics OptiGlass 90L Long Shallow Aquarium (90×25×20cm) 

COMING SOON 

The OptiGlass 90L Long Shallow Aquarium is the perfect choice for creating striking panoramic aquascapes with a unique long, low-profile design. Sometimes referred to as a bookshelf aquarium or bookshelf tank due to its unusual proportions, the Horizon Aquatics OptiGlass 90L offers an impressive 90cm viewing length while standing just 20cm high.

Designed for aquascapers who want the creative freedom of a long, shallow aquarium, the extended footprint provides plenty of room for flowing hardscape layouts, detailed planted displays, and impressive nature-style aquascapes. The unusual proportions are ideal for creating a strong sense of scale and perspective, while the shallow height makes planting, trimming, and ongoing maintenance easy.

Made from low-iron optiwhite glass, this aquarium provides crystal-clear clarity, showcasing vibrant aquatic plants, intricate hardscapes, and natural aquascaping layouts.

Beyond aquarium use, our OptiGlass tanks make excellent terrariums thanks to their clean, minimalist design and crystal-clear glass. The long, shallow dimensions of the 90L are particularly well suited to detailed planted displays, moss gardens, and natural terrarium layouts where horizontal space is key.
