Reproduction

Bannerfish are oviparous, meaning they reproduce by laying eggs. During courtship, males display elaborate behaviours to attract females, including swimming in circular patterns and flaring their fins. After receiving courtship, a female releases her eggs into the water column, where the male fertilises them. The eggs hatch into larvae, which drift with the currents until they settle on the reef and transform into juvenile fish.

Life Span

The life span of bannerfish in the wild can vary, but they typically live for around 5 to 7 years. Factors such as predation, disease, and habitat degradation can influence their longevity in the wild.
