Just picked up my first clam. A Crocea. I have him in the sand bed sitting pointed straight up. It looks like I can see through his shell on the side farthest from me. Kinda looks like he used to be leaning on that side and that is where his foot came out. My question is should I re-place him so that part is in the sand? Leave him, he will adjust to his new position or Let him move himself?
