I noticed that some of my corals look as if they are being attacked by pests (poor pe, brown or off color, little or no growth, and/or thin tissue) so I decided to shake the frags at night to see if anything flies off. I found a few of these guys floating around. I'm pretty sure they're just young bristle worms but I'm not entirely sure. They are less than a centimeter long. I have no evidence of bite marks. I've had aefw in my last tank so I recognize the stress, but I don't know if these are the culprits. No evidence of flatworms, just these little worms. Any ideas?
