Hey, I have a squamosa clam and it isn't doing so well in my 35gal. hex. I have had it for about 3 months now and it isn't opening up that much any more, even when I am trying to feed it. It isn't the only clam in my tank, but it seems to move away from the other clam (durasa). So if you are having the same problem let me know on your methods for reacting to this problem. I need as much info as possible before it is to late.
