Please also excuse my criticism.
Return the clam as it likely will not survive. Some fish, coral and inverts require well established tanks and that is why they are not labeled 'easy to care for"
Clams are not easy and are not for beginners. It is a good idea to ask here before you buy.
If your LFS did not tell you that change LFS.
