Has anyone ever seen one play dead? I was doing a water change and this is the first time it has ever done that... I saw it laying on the sand but still breathing, I got worried and stuck the net in there to move him, he immediately swam away. I figured maybe he got scared because I dropped one of the rocks so I turned off the lights and finished the water change. He is fine, its been hours already and he has been normal. This is the first time I have seen an angel do that... I have heard of the Blue Hippo tang doing this but never an Angel. its a 90 Gal and I only took out about 18-20 gal but this was as I started and I dropped a rock. ( definitely did not come near the fish ).
