I really struggle to capture the true yellow color of this, but it's pretty cool. Like a pastel yellow I guess I'd call it. It also really does reflect blue and green hues as shown. It's also one of the rare corals that I think looks better in daylight than under blues.

You can see a sample frag in the very top left corner of the second pic. And yes, those two emerald crabs shown in the pic have claimed the colony as their home. :-)
