The Caribbean Reef Butterfly Fish is a graceful species featuring a silvery body with bold vertical black bars and a distinctive eyespot near the dorsal fin. Active and elegant, it is a classic marine display fish that brings beauty and movement to larger aquariums.
Origin:
Native to the Western Atlantic and Caribbean, from Florida and the Bahamas down to Brazil.
