Clam mouth problems

I just got my crocea 2 days ago and it looked normal. Today the mouth was wide. I mean really wide. It's extending all the way to the mantle. Is this normal ?
 
kinda like this one. Mine's a little bit more wide though, or as they call it, clam siphon.

In most cases that could be stress related. I have had a crocea that I have had on hold for weeks as he was also gapping like that so I moved him to my 180 SPS/clams tank and he still gaps but has been that was for 7 weeks.

Also have a Viet Nam Squamosa that when the light come on he will gap for a few hours then go back to normal with a hour. Been that way for a month.
