With only 150w bulbs, you'll need to put it up on the rocks (I assume your tank is 18" to 24" deep). To keep clams on the sandbed, a minimum of 250w bulbs is recommended.

Like marinelover said, crocea's are rock-dwellers anyway, and it'll attach with byssal threads and stay put after a couple weeks.
