Moving brown spot on new Elegacne

[JM68]

I just bought this tiny elegance today and after i brought it home and put it in my tank i noticed this small brown spot on it. After about and hour i was looking at it again and noticed that it had moved. I sat and watched it for a while, but couldn't c it moving with my eye(so it must be moving very slowly). Now its about 7 hours later and it has moved about 1 inch lower than it is in the pics. Does anyone know wut this might be or what i can do to get rid of it. Can you do a freshwater dip on an elegance and if so how long. Here's a few pics the spot is pretty obvious.

I'd guess a flatworm. I know there was a big thread about them on elegance corals a few weeks back.

Looks like a flatworm to me too. Did you dip the coral or anything before putting it in your tank?

def a flatworm.
i would perform a freshwater dip asap to kill off those pests hopefully before they spread to anyother coral!
best of luck

Thanx for the quick responses. after doing a little research i think everyone is right I'm pretty sure its a flatworm. its the only one i c on the coral so is there a chance that its the only one?? How long of a freshwater dip should i do to kill these things but not damage the coral?? As i was inspecting the coral more closely i also notice a gall crab that had bored into the elegance and i removed him with tweezers. Hopefully now this little guy will have a better chance at life with these pests gone, but it got a pretty rough start
