Gardiner's Butterflyfish (Chaetodon gardineri)
Gardiner's Butterflyfish (Chaetodon gardineri), also known as Gardner's butterflyfish, is a marine ray-finned fish native to the tropical waters of the northern and western Indian Ocean. Its range extends across the Gulf of Aden, the Arabian Sea, the Gulf of Oman, and along the coastlines of India down to Sri Lanka. Growing up to 17 cm (6.7 inches) in length, it features an oval, laterally compressed body typical of the family Chaetodontidae. The species is recognized by a dusky white body with faint dark diagonal stripes, a distinct black bar running vertically through the eye, a large dark patch covering the upper posterior portion of the body, and bright yellow anal and tail fins edged in yellow along the dorsal fin.
Unlike many of its close shallow-water relatives, Chaetodon gardineri is primarily a deeper-water reef inhabitant. While recorded at depths between 2 and 65 meters, it is most commonly encountered below 25 meters along continental shelf slopes and rocky reef drop-offs. It is an omnivorous browser, feeding on a varied diet of stony coral polyps, algae, polychaete worms, hydroids, tunicates, and small benthic crustaceans. In their natural habitat, adults are typically observed roaming in pairs or small groups, and the species plays an important ecological role as a resident of deep-water coral ecosystems in the Arabian region.
