My 4 clams are still alive. 3 are doing well, 1 is in a breeding trap recovering from being eaten by bristleworms.
A few months back, I switched salts and I think this caused some zooxanthellae in the clams to die and make them smell dead to the bristleworms. Each day, the clams looked worse and worse and it looked like bits of their flesh were chewed from the bottom. So I put them in the floating trap and changed salts back to IO. 3 of the clams have recovered and are now back on the sandbed. The 4th one is still looking like 2 pieces of shell being held together by a thread. The shells are almost separated. However, it looks like a few more weeks or months and it should recover. I had tried prematurely to put the 4th one back on the sandbed but immediately upon placing it there, a huge bristleworm came out and snatched it to its cave beneath the liverock.
I was lucky to save all of my clams.
