War Coral - Nighttime Photography

When the lights go out on the reef tank, all hell breaks loose with the War Coral! There are numerous feeder tentacles waiting for nighttime creatures to accidentally brush against them. I can't image what the sting might feel like on my fingers.

You can even see that the War Coral is attacking the Coralline Algae at the base. It's most likely clearing a space for future expansion of the colony.

I used the camera's built-in flash to capture this nighttime image.

Here's a daytime, close-up image of the War Coral's "peacetime" look.
