Here's the underwater photo of the young adult phase of the yellowtail coris wrasse I pictured two posts below. They go from red with white diamond patterns to this. This is probably the most stunning color phase. Older adults will develop a more greenish-turquoise hue. This pic is my first known repeat on the blog - I'd posted it a couple months back using a photo host which is now down, you may or may not see it in the archives.
