I bought 10 clams from Publix for 50 cents each. I think they are cold water variety. My wife left them in the fridge overnight, I assumed they would be dead or dying the next morning, but to my surprise they were all still closed up. I put them in a bucket and drip acclimated for about 20 minutes and left for work. Came back in yesterday afternoon and they all looked good so I dropped them in the tank. As of this morning 8 of 10 have burrowed into the sand. Think they will survive? If not they should be good food for my clean up crew. If I see them start to open up I will pull them before they rot.
