I have been following this forum since I found it. My Deresa was/is showing signs of pinched mantle. It has had it for a little while (first clam, didn't know anything was wring). So, after reading this thread, I decided to FWD my clam last night.
After the dip and placing back into the tank, I noticed the mouth was a gapping (could see the vents and other innards). It still had "teeth" present around the opening and it had responce (pumped) when fish got too close. My question is (sorry for the hi-jack) is this normal? How long does it take for the clam to respond to the FWD? I fear that I may have been to late in my attempt to fix my clam. Thanks for the responces.
