I need help identifying what this could be on my Yellow Belly Blue Hippo Tang please? She is 13+ years old, approximately 10 inches long, and underwent a stressful situation yesterday as I had to chase down and remove my Wrasse that was picking on her and other tankmates. I’ve been scouring the web for answers and the closest I can find is it’s possibly a Fluke Worm that activated due to stress. Can anyone please confirm and recommend treatment? This is my main and only display tank which I’m in the process of slowly overhauling, hence the bare bottom on that end of tank. Any help is greatly appreciated!
