I have a clam that is doing just fine except for the fact that there are these small tube worms growing on the outside of the clam that touch the mantle of the clam and cause it to close up on that side. Here is a pic. Does anyone have any suggestions. im debating about taking the clam out and scrubbing the shell clean but i dont want to cause more damage cuz i already chipped the edge that is freshly growing by trying to clean it.
