Native to the freshwater streams and rice paddies of South Asia, particularly India, Nepal, Bangladesh, and Bhutan, the zebrafish is a small but striking species, known for its shimmering, iridescent body and distinctive horizontal blue and silver stripes. Highly social and active, these fish are often seen darting through the water in synchronised shoals. Their bold stripes, reminiscent of zebra patterns, not only give them their name but also add a dynamic visual appeal that sets them apart from other freshwater species.
