what to do with clam shell

[renogaw]

this clam shell was given to me from a coworker who went up to maine (he found it on the beach).
i'm thinking of epoxying the clam open a tad and putting corals on it in the tank. zoos, or some type of encrusting sps like Leptoseris?
ou can see how big it is by comparing it to the ice tray i placed for comparison

Nice size chowder clam. I have seen clams that size with a nice mat of GSP growing inside
