Fourspot butterflyfish

[4][5] Butterflyfish as a family are a common marine aquarium specimen as a result of their varying colors and patterns, and contribute to 4% of the global fish trade.[6] As one of 90 extant species in the genus Chaetodon, the fourspot butterflyfish shares the following characteristics: a laterally compressed body with bilateral symmetry, and ctenoid scales, identified by their comb-like edges.[8] C. quadrimaculatus is an obligate, hard coral feeder, an adaptation that is theorized to have evolved approximately 3.2 million years ago.Owing to their obligate dependence on corals, fourspot butterflyfish tend to be distributed in stable feeding territories with high fidelity for each site and male-dominated defense mechanisms.[9] With recent global changes in climate, especially the 2015-2016 rise in water temperatures and mass coral bleaching event in the central Indo-Pacific, this species may have experienced a decrease in food resource.
