泰国礁石鱼类行为：安达曼海洞穴环境中的蝴蝶鱼

aggregation of Vanikoro sweepers (Pempheris vanicolensis) holds formation inside the Fish Bowl chamber of The Chimney at Ko Haa, their bronze bodies and large eyes adapted for low-light cave-dwelling environments visible in detail. This schooling behaviour in enclosed cavern environments is a defining feature of the species, making dive sites like The Chimney ideal for observing natural reef fish ecology at close range. 4K, horizontal, medium, scuba diver POV.
