Compare growth progress of SPS

The picture on top is as it was purchased back on 9/7/05, and the bottom one is current as of 1/7/06:





You can notice significant growth and change:

• The SPS has recovered from those two patches and has covered all previous bare areas.
• The green polyps down the middle between the previous two SPS patches have been overrun, and SPS is gaining ground against the green polyps at the middle top.
• The green polyps have spread significantly around the back and right side (this isn't obvious in the original picture), and have migrated to the base rock at the back, front middle, and front right sides.
• The SPS is touching the base rock and may be spreading onto it at the front left (this isn't obvious in the new picture).
• The white sponge on the right side in the original picture is still there somewhat, but overrun by green polyps (this isn't obvious in the new picture).
• The sponge obvious in the back middle in the old picture has died out; a new sponge is growing out from the lower middle.
• The blue sponge under the front middle in the old picture is no longer evident.
