What is danio?
A danio is any of several slender, hardy, and active tropical fishes belonging to the carp family, Cyprinidae, specifically within the genera Danio and Brachydanio.1
These fish are native to Asia and are typically small, measuring about 4–5 cm (1.5–2 inches) in length, though some species like the giant danio (D. malabaricus) can reach up to 11 cm (4 inches). Due to their active nature and vibrant colors, they are frequently kept in home aquariums. A well-known example is the zebra danio, also known as the zebra fish, which is characterized by its distinctive blue and yellow lengthwise stripes.12
