This is my noob experience. The torch I have was the first coral I bought. It almost died, but had made almost a full recovery. I made two mistakes. Too much current made my polyps start twisting just like yours. Also in start of my tank I was running my lights in a more blue look, not knowing any better to notice the polyps started getting thin a stringy. Between the blue light spectrum and the high flow the polyps started twisting themselves off and floating around the tank stinging other coral it made contact with. I say 70% of the polyps twisted themselves off. I removed a powerhead and I now run my lights mainly in a white spectrum my torch had puffed back up and is keeping is new polyps. Just my personal noob experience
