This is a pic of a small crab that very hard to get a pic of. Shy you see. Only comes out when lights are off....stay's in his little hole in L/R. Any idea's as to what kinda crab it is. Other pic is mabye bristle worm I ain't sure...that why I'm asking you guys. Comes out of the L/R but any movement and it's away. Trying to get better pic.
