This unidentified species of Porites was originally dark brown when I first got it in August 2006 from a fellow hobbyist. It has steadily been changing colors from brown to yellow and appears it will be turning a green color.

Porites tend to look very much like Montipora but usually have smaller polyps. The dark blob is a barnacle living inside the skeleton.

Over the past few months this coral has continued to change color to a green with cyan polyps and growth margins. It has encrusted a significantly sized base attachment (about 4 inches in circumference) to the rock as well. It has a horizontal projection from the rock of about 4 inches.
