Rock Flower Nem moving

[Steelheader09]

I have a Rock Flower Nem that will spend a few days in one spot then then it will move. I have a bare bottom tank with a large hunk of live rock. It stayed under the rock for a while, now its moving. Any idea how to get it to stay put?

Maybe a pile of crushed coral?

Put it into a PVC pipe cap or a hole in the live rock big enough that it can fully retract into.

If I go the crushed coral route, how big should the grain size be?

Decided on a 3x3x3 cube full of crushed coral. I put him on it, we will see what happens!
