I did not know that actually. I have these enormous mushrooms that are trying to smother my zoas but I did not know that they stung. Thanks. I learned something new today!
I am learning so much about coral behavior this week. My Anthelias got stung by a Torch and (even though I moved it) it has started shedding polyps to create new colonies all over my tank. It's like sending superman babies out from Krypton to ensure the survival of the species on new rocks. Everywhere I look, I am finding more. It's kind of freaking me out.
