Foureye Butterflyfish — Postcard

A foureye butterflyfish hovers beside a spray of red algae, its yellow-and-white stripes crisp against blurred tan coral behind it. The dark band across its eye and the false eyespot near its tail are the two marks that give the species its name.

Reef-fish enthusiasts and collectors chasing unusual markings will want this one in the stack.
