Clam warfare?

[madmike]

Hello

I have had a divers den dersa clam in my 225gallon reef for about 6 weeks now and it had been doing great, no signs of trouble. This week, a friend called me and said that his tank had crashed and needed a place to house a couple of his large clams, a 12-16inch and 6inch crocea clam. I said no problem and put them in last night. Today, my dersas shell is open, but the clam has retracted inside and looks like it has pulled away from where it was attached at the top of the shell...it definatley looks like it will be dead soon. Do clams have any kind of chemical warfare? I haven't seen any pests on his clams, but you would think they would have killed his clams as he has had them for a long time. Any ideas on what happened?
Thanks

What was the cause of his tank crash?

We aren't sure. I wasn't able to examine his tank, but i suspect an alk/ca precip as he said his tank turned white and cloudy. He said his levels were ok, but i couldn't verify.

No pics, looked really bad this morning and my cleaner shrimp was having a meal so I pulled it. The two clams introduced recently are doing fine and show no issues.
