Honeycomb cowfish

Sometimes I feel like I have to stalk honeycomb cowfish to get a photo of them, but this morning, one swam right up to me.  I happily took a few photos of it

They are peculiar-looking fish in the boxfish family, with a sharp spine above each eye. These fish were about a foot in length.  They frequently change colors dramatically, ranging from blue to green to yellow.  My favorite color phase is their electric blue phase.
