I have had the calm approximately 5 months, and it has slimed like this since I got it. It shows a white band of new growth on the rim, and I see zero sign of any parasites on it. To all outward appearences it's healthy. It has a clean band of white growth on the edge of it's shell, and no organisms I can see growing there. I cannot get under the clam as I set it in a depression in the rock and it has attached.
I had Crocea clams in a previous tank, and don't remember them sliming like this.
I do have a 6line in the tank, would this be helping to control a parasite I can't see for the moment?
