Schooling Bannerfish is a type of marine butterflyfish found in the Indo-Pacific region. It’s also called the False Moorish Idol.
This fish belongs to the Chaetodontidae family and has ray-like fins. It lives mainly near outer reef slopes and current channels.
Young schooling bannerfish gather around small, isolated reefs, while adults form large groups above the ocean floor.
In Indonesia, this fish is commonly found between 40 to 50 meters deep but can go down to 200 meters.
Schooling bannerfish swim in both bottom and middle water layers (benthopelagic) and eat plankton.
Both young and adult fish sometimes clean other sea creatures by eating parasites off them.
However, this fish is not reef-safe as it can harm coral reefs or other inhabitants.
