I know there is a peanut worm (I think) in one of the rocks that looks completely barren but only one has growth on the outside.
you want coraline algae? is that what you mean? takes time and your water parameters have to be right. you can add supplements from your LFS to make it grown faster. lighting is important obviously and lights in the blue spectrum tend to promote faster coraline growth. no creatures will just magically appear, they are either there or not. you may see some anemones, feather dusters or sponge growth or you may not. the main reason for "live rock" is that it acts as a natural filter wether its is covered in purple and pink coraline algae or not.
