Got this little frag a while back, around the first of the year, I think it was a close out from Ultimate right before they closed. When I bought it I thought they said it was a birds nest, and it was a bit smaller and thinner then, but no matter I thought it was interesting so I stuck it in the back of the tank, and let it grow out some. Had to move it today as my orange monti cap was about to grow into it, and I moved it out where I could get a good look at it. Now I'm beginning to think it could be a Pocillopora Damicornis. Or could it still be a birds nest? How do you tell the difference?
