I've had this clam about 6 months atleast (pic 1) . I recently bought another clam Bc I thought I had these guys under control and since I've added 2nd clam my original one has slowly started to receed and now about a week later it has no mantle showing and is closed up except maybe 1/4 in. The new clam (pic 2) was opening fully for a first day and at LFS
but closed soon after.Nothing else has changed recently except for the addition of the new clam , could this have brought a parasite or something w it? My water parameters are good
I'm pretty positive this is something from the new clam . Should I fresh water dip it?
