I get a kick at looking at growth shots. The first pick is of a frag that I picked up in April. I was told at the time that it was a "neon green acro". The second pick is the same coral about nine months later. I had it laying on my sand bed for aproximately the first four months, because I was unsure what I was going to do with it. During that time it did turn bright green. Most of the growth you see is over the last five months or so, when I moved it up much higher in my tank. Since then the new growth has taken on a bluish hue to it.
