More pictures? No problem!
Here is a sequence of photos for a wild tonga piece that is one of my favorites. I originally acquired it in November 2006.
As reputable with most tonga corals, over the next two months it gradually browned. Here it is January 23rd, 2007.
Here is is today.

It is still hard to capture it's colors (the 2nd brown photo is very accurate though lol), but it is now more of an ice blue than the original ice purple color.
