I was just at my friend's house, after he had called me to come over and see something unusual.
Well when I got there, I saw his Purple tang eating the mantel of almost all his clams. On some occasions the tang would take part of the clam's newly grown shell with it.
Weird I have heard many fish eating clams before, but never a Purple tang. We took all the clams out and put them in my tank for now until we get the tang out. He wants to buy a fish trap, to get it out. I have told him that he is going to have to tear down some of the reef, in order to get the tang out. Has anyone ever seen a purple tang do this.
