The yellow chub in this photo is actually a gray chub, but a few individuals, such as this one, can be yellow, white, or multicolored. This one is something of a regular at one spot on the North Kohala coast.

The orangespine unicornfish is seen in many places along the coast and always has a grumpy look. In this case, it looks like it’s upset that the chub has swum into its territory.
