Has anyone had problems with a Yellow coris nipping on their clams. They have been together for over a year no problems. The clam is always out in the day, but the last couple of days he is pulled in and trying to ease out. The Coris is spending a lot of time and curiosity around the clam. I see no parasites such a pyramid snails that he would be attracted to. I am wondering if he has developed a taste for clam.
