Auriga Butterflyfish (Chaetodon auriga) Care
The Auriga Butterflyfish, Chaetodon auriga, is also known as the Threadfin Butterflyfish and Diagonal Butterflyfish. These fish come from across the entire Indo-Pacific region. They have a silvery-white body with a black band across the eye and diagonal black lines that are perpendicular to one another, creating a chevron-type patterning. The back section of the body fades into a bright yellow; some have a black eyespot on the upper part of the dorsal fin. These are one of the hardiest and most popular of the butterflyfish.
Butterflyfish are omnivores and require a diet rich in both meaty foods and plant-based foods. They will eat flake food, algae, frozen plankton, mysis and brine shrimp, and live shrimp and worms. They should be fed several times a day.
The Auriga Butterflyfish can reach lengths of up to 8″ to 9″ and will do best in an aquarium of at least 125 gallons with plenty of live rock to graze on and hide in. They will thrive in large fish-only aquariums with lots of open swimming space and live rock hiding places.
The fish is not reef safe and will eat various types of corals.
