About the Threadfin Butterfly (M)

The threadfin, or auriga, butterflyfish is one of the more popular butterflies, with white chevron-lined sides, yellow fins and a thin filament trailing from the dorsal fin. This is a medium-sized fish; adults reach about 9 inches and need a fish-only tank of 125 gallons or more. It picks at corals, anemones and tube worms, but it takes mysis and other meaty foods well when fed several times a day.
