Clam taking nose dives

[Palmer]

Hi Everyone

I have had a maxima clam for about a year which has been sitting on a piece of dry rock that sort of cradles it right on the sand bed. It is directly in the light and has been doing very well this way since I have had it. For some reason lately it keeps hopping off and landing on its side on the sand bed. Twice I have put it back but this morning I just left it there.

Is this a problem? I thought it would be because the mantle will not receive as much light?

What would you do?
