Description
The Threeband Demoiselle is a popular saltwater fish recognized by its distinctive black and white vertical banding. This hardy and active species is often found in coral reefs throughout the Indo-Pacific. While generally easy to care for, it can be territorial, especially towards conspecifics or smaller, more docile tankmates.
