Your previous posts suggested the change was done prior to the clams acting up, hence my previous assumption. Keep in mind a 10% change after 6 months won't have much effect, you can't rule out this issue from that. You can search day and night for some mysterious predator but clams don't have the ability to reason, it's not closing up all day because it's more likely to be attacked then. Clams sense light and touch, they close up temporarily with sudden changes in those senses. The clams are stressed making them more sensitive to light is all.

My honest guess is months of neglect among other things. It was probably a combination of things from the tank being fairly new to a dramatic light change and then the constant downfall of water chemistry from lack of maintenance. In the end the clams have finally had enough and are showing signs of stress which may or may not be reversible. Your best shot is to eliminate the more potential issues with IMO doesn't include moving them or building cages. First check for pyramid snails, these are really the only predator that could cause such issues, if you have them they are easily spotted on the clams foot. Daily water changes of around 20% for the next week or so should slowly bring up strontium, iodine and anything else they require. Calcium and Alkalinity should be careful monitored and even verified to be certain readings are accurate. The water movement around the clams should be moderate and indirect in enhance their ability to feed. Cutting your light back might also aid in recovery as well removing any aggressive type of chemical filtration. Finally I would try intermittent skimming and dosing a small amount of phytoplankton.

You're looking at less than an hour a day for one week. You probably spend more time on this site complaining about spelling. You'll also spend more time trying to capture imaginary fish in the act. It's becoming more clear you're just looking for the easiest answer which I think is selling the clams, I'd take the offer, I'd never pay that for half dead clams.
