Bought 6 about 2-3 weeks ago placed them in a bowl with SW
and let them sit for 30-40 min till they opened up and sucked in some new water and got rid of the old water they had. Then I tossed them in my fuge, within 30 min they started to bury themselves and in a few hours they were gone. I dug them up the other day to make sure they are still alive and they were. You can see there foot sticking out of the sand if you look close...
I would not say they are cold water clams, they do have them in Fla and the bays in NY get warm in the summers. They look like the same clam that the sell on SWF for $4 a piece. I got 6 for under $2. someting different. I have not checked my NO3
yet to see where it is.... I will today
