I am very new to clams and had my first maxima arrive yesterday via shipping. He seems very healthy, but this morning he was doing something weird, and I don't know what this means..... So when I took him out of the bag yesterday he had several white "legs" dangling from the bottom of his shell. I put him on a rock and he seemed happy, moved a little bit to the side but that was all. This morning he was separated from the white "legs" and over on his side. He also moved about two inches to the right. Now I know maximas attach with threads into the rock, and I can see one or two threads going from his shell to the rock, but I'm wondering why he moved and left those white "legs" behind, and if he is okay? Thanks!!
