Took this video of the pumping xenia “pumping” in my tank using my DSLR. While I hate to admit it, for convenience I take almost all of my photos and videos exclusively with my iPhone. But the quality between an iPhone photo/video and a professional grade DSLR is still.. quite large- evidence in all the details you can see in this video below. There are many theories of why the xenia coral “pump”. But none have been conclusive. Regardless, my wife loves these little things because of how active they are.
Here is the clump of xenia you see above. The color below looks more true to the eye though as I have AI SOL blue over the tank. But more detail can be shown once the white balance is adjusted for the video above.
