These Fish Can Change Colors!
It took me 6 shots to get the sun in the right spot and angle with these crescent-tail bigeye (Priacanthus hamrur). After each shot the flash from my strobe made the scatter, but after about a minute of waiting quietly they would gather again. I saw some of them change color to more silvery color then back to red. I wondered if stress causes them to change color so I looked it up later. I found out they have ability to rapidly intensify or fade color and markings.
