I find this very interesting. There are two pieces of echinata on this frag plug. One was what survived of my colony when I moved. Its the very green encrusting piece. The other is a piece I got back from a buddy that was from my original colony.
If you notice at the bottom of the bluer piece, you'll see that it has touched the greener piece and now that area is bluer but it still retains the green polyps. Its like grafting a piece of Hawkins echinata back to itself and seeing the slow transfer of color through the green piece. It'd be interesting to see when the green polyps go blue.
