The balloon marble gourami, also known as Trichogaster trichopterus, is a freshwater fish species that is a color variation of the popular gourami. They are named for their round, balloon-like shape and marbled pattern. Balloon marble gouramis are relatively small, typically growing up to 3-4 inches in length, and are known for their peaceful nature and ability to thrive in community aquariums. They require a well-maintained aquarium with plenty of hiding places, plants, and a varied diet. Balloon marble gouramis are popular among beginner and experienced aquarists for their unique appearance and easy-to-care-for nature. They are suitable for community aquariums and can be housed with other peaceful fish species.
