Need help to identify

[paulmont1719]

I ordered a clam from my lfs, it was supposed to be a Derasa. After the excitement of the new clam andgot it in the tank last night I’m thinking it’s a crocea or max. Sorry for the bad pics m. Thanks for all the help!

Unlike some of the others. Once the derasa opens up, you’ll know if it is in fact a derasa.

Hard to get a decent pic

Without really looking at the shell , I’d kinda say no.
The derasa is pretty easy to spot as the mantle doesn’t usually overlap the shell much. It’s well known for the wide inset of the mantle.

If you can get one more pic of the clam wide like this we’ll see if the rest of the #reefsqaud clam heads will chime in.

Tridacna maxima. Derasa can have schutes on rare occasions but that's a maxima.
