This is a unidentified species of acropora that seemed like a pretty deep purple at the LFS.

To the eye it looks fairly purple but to the camera it looks much more brown.

The frag also has a crab within its branches.

This picture shows the coral one month after being added to the display tank. The coloration of the coral has increased significantly.

Some new growth is evident mainly in areas where the coral has anchored itself to the rocks and encrusted over the epoxy putty.

This coral has continued to change color to a nice shade of blue.

The growth rate of the coral seems pretty slow. However new growth can clearly bee seen encrusted along the rock.

This is also the first picture to show extended polyps.

The color of this acropora species is still excellent.

Polyp extension is very good now and fully extended during the day as well.

Growth rate overall is still very slow, however it is showing significant new encrusting growth.

This is a macro image as viewed from above.

Notice the glowing ring at the base of some of the polyps. I have not noticed this before on other acropora species.

Considering how slow this coral grows it is showing very good growth and decent color.
