Here is an image of the original frag. I was really sad to lose it since it had such amazing color. The polyps were bright red-orange and the flesh ranged from banana yellow to almost sky blue.

Sample prep on this sample was similar to the Pocillopora sample. Images were acquired on a Hitachi 4800 Field Emission Gun SEM.  The skeleton has some interesting structure:

And the tip of one of those tines from the polyp area:

Here’s another area of the skeleton that I zoomed in on. There are some very different structures here:

I'm a passionate aquarist of over 30 years, a coral reef lover, and the blog editor for Advanced Aquarist. While aquarium gadgets interest me, it's really livestock (especially fish), artistry of aquariums, and "method behind the madness" processes that captivate my attention.
