If you are on the fence about ordering uncured live rock from these guys, take the plunge and order already! You will not be disappointed! This is by far the best rock I have encountered! Covered in multiple colors of coralline, sponges, and macro algae. Within an hour in my tank I encountered 3 shrimp, a crab, an urchin, and countless feather like filter feeders. Do yourself a favor and order this rock!
