I have kept many crocea and maxima clams in the past with my current set-up. I sold those clams and decides to keep a few 'gems'. I purchased one crocea maybe a little over 3" that arrived at a LFS the night before. Acclimated it right and I within 9hrs there was barelt any flesh. What happened to my clam? I want to find out before I go and purchase another clam with the same fate.
