I'm new to saltwater aquariums. I had my tank for a couple of weeks and I put some LPS corals in - including a torch. It looked good for some days, but then it didn't open anymore. Yesterday - after a week - one head died and today another seems to be dying as well. When I took out the torch, I saw something wrapped around its head. This one sticks to the skeleton of the torch, it's neither soft nor hard, I can tell it's organic. Do you know what it is?
Thanks for your help.
