Unfortunatly I can not get a picture of this. I bought a clam and put it in my aquarium (without letting it touch the air and after aclimating). It has been in my tank for about 4 days now and I looked at the bottom of the clam (wher the joint for the shell is) and saw something white coming out of the back. When I came back later there was a fuzzy white ball that was laying below that area. sort of like a tiny white kush ball. Can anyone tell me what this is? Should I be concerned? The clam appears to be opening and closing fine.
