I have had these Zoas for a couple of years. Just a few polyps on a piece of live rock that never did much. After changing my lights to LEDs and transferring them to a frag plug, they have finally started to grow. Don't quite know where they came from - whether they were hitchhikers on the rock. or came from some trade (I do remember getting some African Hornets long ago).
Are they Purple Hornets?
They have purple faces, alternating purple and yellow fringe and a distinct yellow ring.
From what I can see, they are identical to the pictures here:

I have no skills to take photos of Corals even with a good dSLR. This picture was taken with my phone. Pretty poor quality but it gives you an idea of what they look like. They only thing done to the image was a bit of cropping.
Are they the real deal?
