I have a whitetail bristletooth tang that’s suddenly showing signs of stress. He’s been in my tank for over a year and there haven’t been any new additions. As you can see on the video he is pacing against the glass on one side of the tank for the last few days. Nothing has changed parameter wise. 220 mixed reef, 1.026, .1 po4, 15 no3, and temp 79.
