Pinched Mantle or Pyramid Snail Result?

[triscene]

Hello guys, i have bought good clam in my LFS but realized after placing to aquarium that mantles are not opening as usual. After several days i have inspected the clam and found several pyramid snails and did the clean up for two days straight (Sunday, Monday) but clam looks still like on the picture. I have second clam doing well for more than a year with great growth and mantles.
Any advice from experienced folks?

It is so hard to say. Some of them are shy when in a new home since they are not used to the new light - mine don't like to go into the tank from the QT since they are not used to fish swimming above them and constantly close up when a fish swims overhead... but then in a few weeks, they are back to normal and don't even flinch anymore.

It is possible that the clam was on it's last leg and the move has finished it off and it is starting to die.

If you have good water and light, then all that you can really do is wait and see.

What did they sell it as? Looks like a maxea to me... cross between a crocea and maxima since it has some larger scutes... but it could just be a crocea.

I have maxima and it has much larger scutes, should be crocea
Thanks for advice and your knowledge. Will be having eye on her

From other photos I've seen, it looks like it has already started to gape. ��

Looks like the mantle is not extending very much. Hard to tell if there is 'mouth' gape. Both would indicate stress but not, necessarily, imminent death. If you got to the snails in time you may be okay there. Sometimes a move to a new system can cause quite a bit of stress. If it does not 'perk' up within the first few days to a week it could be something more than just recovery from the move/snails.
How's it looking now?
