There are variation and different names. The general category of these fish consists of bottom dwellers who lie in wait for prey. They are camouflaged well. Their prey are unsuspecting fish going by. This odd color teal is a first for me. It is pretty, but he kind of stands out. When he swims the underside of his fins are bright orange and yellow. To make sense of the shot, you look for the eyes and the mouth. Of course don’t get close. They are said to be very poisonous.
