I have a 5" Derasa clam, I've had it for a year now, it was 4" when I got it, and I noticed last night and today that it was laying on it's side . I went to stand it up, I used a long rod to gently nudge it with, and I noticed that it seems as if the 2 sides of the shell moved sepreately from each other, almost as if they were no longer attached to each other or as if the "connector" between them was weak. I did notice the other day that it seemed to have released some filaments that were attached to some sand, there wasn't much there. It has never been attached to any LR and has always been on the SB.
It's on the SB and I haven't seen any snails or any other creatures around it or bothering it. The water params are all in check, Trites, trates, ammonia and Phos all 0, salinity 1.025, PH 8.3, calcium 350-400 (I drip kalk daily), Alk 9.5-10 DKH... It's mantle is extending out full and other than the problem with the shell, it seems to be very healthy. It extended outit's mantle within minutes after I stood itup. About 4 days ago I moved it to remove a piece of Xenia, that had released itself from it's perch on the LR, and that's when I noticed the small piece of filaments from the clam. The 2 halves of the shell seemed to be fine at that time and the clam closed up tight. Today is the first time I've noticed any problems with the clam. Of course I don't make it a habit of moving things around in my tank. I only decided to stand the clam up because this was the first time I have ever seen it laying on it's side. Everything else in the tank seems to be fine and healthy, corals, fish and LT anenome. Has the loss of the filaments weakened the shell where it's joined? Will it strengthen back up? I just would hate to loose the clam. I also have a Squamosa clam, they are about 2"-3" apart and it's fine. Thanks for any help and advise.
