these shots show the colors that corals fluoresce when they are in only blue light. not all corals do this, but many will reflect the blue absorb the blue light and reflect it back as another color. one way to do this is to take shots under actinic lights only with a yellow filter. these are taken under blue led moonlight with the camera adjusting the white balance to get rid of the blue. they are also low exposure shots to capture the light the corals are fluorescing.

i will post some of the corals in daylight to show how the colors change.

like i said, not all corals do this. for example, these corals
