Hey everybody, I am sort of shocked of what happened to my tang. Usually it comes out in the morning to be fed and swim around. I come to my tank and there is no signs of him and I cannot see it. Does anybody know what may have happened, if he is hiding, scared, or something. He is a healthy little guy and I have noting agressive in my tank that would have harmed him. Somebody please help me out here. Here is a picture of him. He was eating and thriving as well.
