New Aquarium question

Hello-
I just started a new marine aquarium of thirty gallons about 6 weeks ago. I have just noticed some life on the side of the tank and I have no idea what it could be. There are about 13 of these little (about the size of a small pencil dot) creatures. They have multiple legs and look like tiny crabs. They don't move about at all, just stick on the glass.
This tank is newly cycled. I have live rock, a feather duster, some snails and hermit crabs and two clownfish. Everything seems to be doing well. But I have no idea what these creatures may be and am concerned that they may be parasites?? They have been multiplying ever since I noticed them.....started with two and now there are 13.
Any ideas? Thanks in advance for any help.
Molly
