The Auriga Butterflyfish (Chaetodon auriga) is among the most recognizable butterflyfishes of the Indo-Pacific. Its laterally compressed body is white to silver, crossed by intersecting dark chevron and diagonal lines that shift direction across the flanks, with a black bar masking the eye and a wash of yellow across the rear body and fins. Mature fish extend a trailing filament from the soft dorsal fin, and most populations carry a dark eyespot near the top of the dorsal, though Red Sea specimens frequently lack it. Adults reach roughly 10 inches.

In the wild this species ranges across tropical coral reefs, lagoons, reef flats, seaward slopes, inshore waters, and rubble or weedy areas, grazing over a wide variety of surfaces. That foraging habit should shape the aquarium layout: build generous rockwork for picking and shelter while preserving substantial open water for cruising. A 125-gallon aquarium is the practical adult minimum, and the system should be mature and stable before a specimen is introduced. Given the fish's size and appetite, efficient filtration and consistent husbandry matter more than decorative complexity alone.
