Madagascar Rainbowfish (Bedotia geayi) is a freshwater fish species native to Madagascar. They are known for their colorful and lively appearance. These rainbowfish have a slender body shape and are typically around 4 to 5 inches in length.
Their coloration can vary, but they often exhibit shades of blue, green, and yellow, with some individuals displaying a rainbow-like iridescence, especially during courtship and when they are in peak condition. The males are usually more colorful than the females.
Madagascar Rainbowfish are social and should be kept in groups to bring out their natural behavior. They are relatively peaceful and make a great addition to a well-maintained aquarium with plenty of swimming space and places to hide. They prefer slightly alkaline water conditions, and their diet should include a variety of high-quality flakes and small live or frozen foods.
