biOrb was developed to have the visual appeal of a traditional gold fish bowl combined with the filtration of an technologically advanced aquarium. The original biOrb 30 was launched in 1999. Since then the classic shape has been developed into a range of sizes to suit all homes and pockets. All biOrbs use our patented filtration system. Circular water flow means there aren’t any ‘dead spots’ in a biOrb aquarium.
