Stoplight parrotfish

In Bonaire, parrotfish play an important ecological role on the reefs.  They graze algae off rocks and coral.  In some countries where parrotfish are not abundant, algae over-grows the reefs.  But here, they are all over the place, and they keep Bonaire's reefs healthier. As a bonus, many of them are strikingly beautiful.

These photos are of a terminal phase stoplight parrotfish. This phase is the largest, getting up to 2 feet. However, this fish was only about 16 inches long.
