I have had a saltwater tank setup for about five months now. I have had a clown fish and a yellow tang. Just recently I have noticed that when I turn my light off the yellow tang gets really pale and acts as if he is dying. The clown fish starts to swim kinda funny. I'm confused, I feed them, change the water, all the parameters are normal. Its just when I turn off the light. Can anyone help?
