Acropora micropthalma
Grown from a couple of twigs of Scripps Acropora - Acropora micropthalma, I have several small colonies in my tank a year later. Originally shared from the Scripps Institute's reef tank. This is a very fast grower, but rather frail. It is easy to accidentally frag it while working in the tank, but those pieces can be mounted elsewhere to grow out. Great coral.
