Well tonight I was staring at my tank as usual, when my tang picked off a something white off of the live rock, then it let it go. When it landed on another piece of rock it started to move, it looked and moved like a serpent star but it was baby size, it had a clearly visible centeral disk with 5 long lanky legs, one was a little shorter than the others due to the tang. The only thing it that it was only the size of a nickel and kind of white in color. I would get but being that size and trying to find it again could be a little hard.
