    Hi! I noticed a nasty lil worm thing moving, inching its way out of a hole in the rock. Obviously I was curious to see what the heck it was so I turned the tank light on and it shrunk back in the hole. I'm new to saltwater tank keeping so I just want to make sure this isn't a harmful parasite of...

    Worm Id hitchhiker

    I found this worm in my tank a week or so ago. I decided to pull it out tonight to get a better look at it. I don’t think it’s a bristle worm. I’m worried it may be a bobbit worm of some sort. Can someone ID? And tell if it’s dangerous or not. Thanks.

    Little Worm ID

    Hi All, I am hoping someone can ID this guy. It came off an elegance coral that was in QT. This was the coral's second dip, so I am assuming that there was an egg that I missed when cleaning it the first time. Any help would be appreciated. Thanks
