Both are white with thin vertical lines and a large black area along the back to the tail base. Spot-nape Butterflyfish has its black eyestripe broken above the eyes, which leaves a separate black spot on the nape, and black and orange marks in its yellow fins. Lined Butterflyfish has an unbroken eyestripe and plain yellow fins, and grows far larger -- up to 30 cm, as big as a dinner plate.
