Clowns and bubble coral

[Coralgurl]

How do I know when the nem has put it's foot down? I've had my power heads off, but turned the mp 10 on yesterday, I was home all day and could keep an eye on things, nem hasn't moved, tucked into the rock. Should I turn the mp 40 on and see what happens? The 10 doesn't seem to push a lot of water where the nem is located. I'm hoping the nem stays where it is, front and centre...lol
