I know it's not the best picture but can anyone id

the coiled thing next to the coral? At first I thought it looked like poo, but it has moved closer to the drag and I see another one near some zoas

Thanks guys. I had just never seen it solid like that in the tank. Then to see 2 with one moving/floating towards the drag, I figured it was best to ask.
