I am definitely new to all of this so I really need some input. I received a lionfish from someone as I was starting my tank. He seems really health and loves to swim around the tank. His colors are good and he eats only shrimp pieces 3 times a day. The thing that I am questioning is: I have 2 bridges setup up of live rock and he loves to go underneath one of the bridges and hang upside down. :neutral: Sometimes he sit horizontal, vertical, and upside down too. I am just wondering if that is normal behavior for a lionfish? Please let me know. Thank you :smile:
