Yes they do, I take a razer blade and cut as close to the object they are attached to as possible to minimize tissue damage. Within 12 hours of placing them onto a different surface they'd re-attach.
Curious if you have any luck with maximas long term. The seem to get pinched mantle disease easier than all other clam types I have. Do you perform freshwater dips when you get them.
great question- so far I must agree with you on that statement based on my experience. My maximas don't really have a good survival rate and I suspect that's from the pinched mantle disease as all the once that have died displayed this.
