Good idea on going slow. Even though the tank might be "cycled" it's not done yet
And as the tank just did finish cycling, you'll now start to see more and more things start popping out of the live rock. I can remember when I set up our first tank and were oohing and ahhing over one or two little dusters on the rocks; now they are everywhere
If you really don't see any in a few weeks, check at the LFS the next time you are in and see if there are any down in the sand of one of their tanks they'll let you scoop up or look for a
reef club in your area where you might be able to get some from a fellow reefer.
Have fun!
