Hello, I’m new to this forum stuff so I’m just going to try my best to keep this short. I’ve been doing saltwater aquariums for roughly 20+ years and still learning. Lately I have watched my purple tang go around rocks in a pattern that is the same for several minutes each night. What I need to know is , is this a normal crazy pattern he just likes to do or is there something I should do that he needs. He looks likes he on a Ferris wheel. lol . I have a video that I’ll share if I can post it for all to watch. He in the background.
