About the Bluespot Butterfly

The bluespot butterflyfish is bright yellow with a long blue patch on each side, a black eye bar and a blue-ringed black spot near the tail, and grows to about 6 inches. In the wild adults feed almost only on live coral polyps, so it is a demanding fish that suits experienced keepers with a fish-only tank. Choose one that is already eating frozen foods and offer small meals several times a day.
