Wow I really don't think Cobalt is being rude in any manner. If anything you are being hyper sensitive about the situation! Clams do die and it can happen unexpectedly and with no change! I had mine in a tank for 4 - 6 months and one day the first closed up and opened dead.... This happend to the other 2 about a month later as well. I'ts not like he was calling you out saying your clams suck, because they obviously don't! they are beautiful looking clams! I wish i would have had money cause I would have bought all of them! They do need time to adjust to the change, especially with the lighting change and the water change. I mean heck if you threw someone in the woods that had never been in the outdoors how do you think they would feel? Personally i would be freakin out too! But ALL live stock does take a little bit to adjust to the new surroundings. Just let them be for awhile, and see what happens.
