Encouraging an RBTA to move where I want him

[trilinearmipmap]

Got an RBTA clone 3 days ago (thanks Sam).

Placed him on the rockwork, he went and hid underneath the rocks.

Now his foot is under the rocks and the body/tentacles of the anemone are facing up out of the rockwork towards the light, but it the back of the tank so he is not visible from the front.

My plan for the next week is to wait and watch, but I want the anemone in the front of the tank where he can be seen.

The two methods I thought of were: aim a powerhead at him, or cover the top of the tank over the anemone to block out his lighting and make him move.

Any thoughts?
