+Razor Posted July 17, 2009 Share Posted July 17, 2009 Can someone help me ID these? I can't tell if the green one is a brittle star or green serpent star. The redish brown arms I believe are a brittle star also. Both of these are held up inside the live rock and have not came out at all.

+Razor Posted July 17, 2009 Author Share Posted July 17, 2009 What you see in the pics are the only thing I've seen of them over the past week. Quote Link to comment Share on other sites More sharing options...
+Daniel Posted July 17, 2009 Share Posted July 17, 2009 Look like bristle worms to me. The majority of them are perfectly harmless and add to the bio diversity of your aquarium. However, be careful not to touch them as I hear they have a painful bite/sting. Monitor their activity and confirm they don't affect any of your corals/livestock.

Zarathustra2 Posted July 18, 2009 Share Posted July 18, 2009 +1 for bristle worms. I have the exact same ones in my tank. If you see ones that get too big (longer than a couple of inches) just yank them out with a pair of tweezers. Quote Link to comment Share on other sites More sharing options...
WesleyB Posted July 18, 2009 Share Posted July 18, 2009 They are harmless and are nocturnal so you won't see alot of activity out of em during the day. The brown one's mainly feed off detritus. Quote Link to comment Share on other sites More sharing options...
mFrame Posted July 18, 2009 Share Posted July 18, 2009 Yep, bristle worms. I have one large one that will steal food away from crabs and corals by the rock it lives in. Quote Link to comment Share on other sites More sharing options...
