I have a iridescent shark. He is about 2 1/2 inches long and has been really active since I got him about a week and a half ago. Well today he did something strange which has got me worried. I introduced t painted glass tetras into the tank and the ID shark started playing dead on the bottom of the tank! At least thats what I hope he is doing. He sits still on the bottom, and even turns upside down. But he is breathing the whole time. I will come back later and hes in a different spot doing it. Is this normal for this fish?
