lol, it might be the only time he ever sees it. I've learned that if I see something that needs ID I need to pull it out while I have the chance and then find out what it is. You don't want some fish grabbing brittle growing up in your rocks until one day your fish start disappearing like the folks in predator. By the time you know what's going on you'll be like "Get to the choppah ahhheeeeahhhhheeeeahhhheeeee!"
