Crocea mad?

[Electrobes]

Okay so my crocea in my clam tank seems a bit angry. After having it for a couple months... its now closed up.. with its mantle a bit out. Granted I have seen it only today like that... any ideas what it could be? I did have an earlier sandstorm... but the other 5 clams look fine. Thank you for reading!

ime, croceas can be the moodiest/most sensitive of clams- almost like star polyps if things aren't just right- give it another day, then see....good luck-
