I am kind of new to salt water fish, well I am brand new and am just setting up a new tank. I put in some live rock the other day, and later that night I was taking a look around and noticed a very small crab in there. As soon as I turned the light on to get a better look it disapeared into a crevice in the rock. I am hoping this is not too much of a bad thing. I am not sure of what kind it is, but it had black on it's pinchers and it looked a bit furry, and the main clour was white. It is about the size of my thunbnail. Does anybody know what type of crab this is and what I should do. I have no idea of how to get rid of this thing. It moves so fast and hides in the rock. I have only seen it 2 times in the last week and it was in different places each time so I have no clue if it has made an offiical home yet. I just do not want to start stocking with hermit crabs and fish and stuff and have this thing get big and destroy my tank and the marine life that I am going to ty so hard to keep. What sould I do??
