Hey what’s up everyone. Recently got a derasa clam from ORA. Arrived at what looked like a slight rip in the mantle. For whatever reason today, seems like it’s more torn? I don’t suspect anything in my tank harassing the derasa as I’ve had a crocea for the last 6 months with no issues. Does this look like Pinched Mantle Disease? Wanted to hear some feedback/opinions. The “tear” is on the bottom middle of the clam.
