Reef fish are a physically and functionally diverse group of organisms that live in close association with coral reef habitats. Chaetodontidae represents the most species rich family of corallivorous fish, and their reliance on corals as food resources has led to their designation as indicator species of coral cover and health. However, the majority of research on the foraging ecology of Caribbean Chaetodontids dates back several decades, and therefore does not account for recent changes in coral community composition as the result of disease, climate change, and other stressors. As the novel and deadly stony coral tissue loss disease (SCTLD) …
