Betta Backgrounds have been designed to enhance aquariums and reptile environments. They are all double-sided with different themes on each side. These vary from plain blue or black, tropical underwater plants, rocks, wood, coral, ruins and even desert scapes. They are available in several sizes ranging from 30cm to 60cm tall. Easy to install, can be fitted on either the outside or the inside (enhances the appearance greatly) of aquariums, terrariums or vivariums.
