I recently got a zoanthid frag pack from WWC, I’m new to the hobby and only have one nano reef so I did not have anything to really quarantine my frags in so I just gently shook the frags in my own saltwater after acclimating them and took the chance and put them straight into the tank. I know it was a mistake I was just so eager, anyway it’s day two of having them in my reef tank and I spotted a few centipede looking bugs around my zoa’s. Does anyone have any idea what this thing is ? Is it bad? Harmless? All the zoanthids are open and looking happy right now except the one that I spotted the critters on, the skirt isn’t completely open but it’s also not closed. Any info would really be appreciated as I’m literally brand new to the hobby I want to learn everything I can possible. Thanks everyone
