I saw that Elletek mentioned something about Fire Coral in the sea lice discussion. My husband and I will be in Cozumel in a few months for the first time. We love to snorkel but I am a little nervous about running into fire coral. I read into it some and read that it can be very painful and last for several days sometimes. I am wondering if this is something we will likely see in shallow snorkeling water or is it more common in deeper, scuba water.
