Clam trouble

[JASON1238]

My Tridacna Crocea Clam has not been opening fully for a few weeks now. I saw somewhere ther are some type of parasites or snails that inhabit the underside causing this problem eating the clam from the bottom. After I looked it over there were black colored (very small) bugs and one snail under the bottom. Anyone who knows what this is and how to get rid of it? Thanks

I would go with a FW dip, but I've never had that same problem. maybe someone could add to this.
