Green monti. 1, brown 0

[George]

I got this idea from a LFS.
I mounted two different colors of Montipora Digitata 1" apart. The bases grew toward each other fast. Whey they met, a visible white band was formed. I know now that the band was brown ones skeleton, 'cause the brown sp. was pushed back by the green sp..
From the photo, left is the brown one and right is the green. The small patch on the bottom is brown sp. used to connect with the mother colony on the left. But now it was cut off by the green. I think it won't be long that little patch will be covered with green sp.
Sorry for the color of the picture. It's more distinguishable when you see it in person.
