Which fish is commonly recognized for its small size and distinct stripes in Hawaii?

The fish commonly recognized for its small size and distinct stripes in Hawaii is the Manini. This species, also known as the convict tang, is well-known for its vibrant coloration, featuring bold black and white stripes, which make it easily identifiable. The Manini thrives in coral reef environments, where it often plays a role in maintaining the health of the reef ecosystem by grazing on algae.

The other options, while they refer to fish found in Hawaiian waters, do not share the distinctive small size and striped appearance characteristic of the Manini. For example, Ahi refers to yellowfin tuna, which is significantly larger and does not have stripes in the way that the Manini does. Understanding the specific attributes of these fish highlights the unique biodiversity in Hawaiian waters and allows for a greater appreciation of marine life in the region.
