Is my clam gapin?

Hey guys. Just wondering if my clam is gaping. Thanks.

Is it attached to the rock under it? If it is it probably is not gapping. If it is not attached carefully lift it and look at the opening between the shell halves where the byssal threads normally grow to attach to a rock. Normally this area is covered with tissue. If it's open and not covered by tissue then it is gapping.

Nope, but is that a torch to the right? Hard to tell.
If so, it will sting the mantle.
If not, no worries, just keep chemistry stable.

Hey guys. Just wondering if my clam is gaping. Thanks.

When did you get him?
Also can we see both siphons and not just that one?
He may not be gaping - my clams will open their excurrent siphons widely to expel any wastewater every so often. Although when they do they open wide (similarly to the clam in the photo) for a few seconds and then close up again.

I assume next to it is instead a Ricordea yuma (not a torch unlike the thought above). I would still move the clam, I assume this species is a Squamosa and if I am correct then it will likely prefer being on the sand or closer to the sandbed long term. Maxima, Crocea and Noae all prefer to be in the rockwork however Gigas, Squamosa and Deresa all prefer to be closer to the sandbed as they aren’t likely to fall once they get larger - these are clams that once they get large they don’t use byssal threads to stay stable and instead will release them and rely on their own weight to stay upright.

I’ve had him for a few months now. He’s attached to the rock scape. It’s weird cause I’ve never seen it do this.
