So I have a blue tang that has recently become comfortable in the tank, she is exploring all over and stays out when I am in the room. the weird/funny part comes when i put nori on a clip in the tank - she INSTANTLY races into the rocks and wedges herself in a cave, i've seen her do it each time i've tried to put nori in the tank, she's terrified of it lol! does anyone else have tangs that are similarly silly?
