I was so engulfed in the Zen of illustration, that I forgot to save an in progress of the the color on these two. Hairy frog fish move by gulping in water and propelling it out their gills. They steady themselves with their little fin "feet". Mostly they remain motionless on the bottom and camouflage perfectly in with coral and sponges. The wave their lure enticingly and snap up prey with an amazing strike speed. They will even try to eat fish much larger than themselves. They change color as they age, going through a wide range of hues in their lifetimes.
Personally, I think their striation brings to mind the lion fish. I wonder if they are relatives.
