Wow, nice live rock which such interesting hitchhikers. Allow me to recommend my favoriate reef aquaria forum, Reef Central. There you will find the [Ask Dr. Ron](http://reefcentral.com/forums/forumdisplay.php?s=&forumid=40) forum where he can identify just about anything that can be identified without dissection. FWIW, I’d hazard a guess that it’s probably carnivorous and unwelcome in your tank. ---

there’s a fun new hitch hiker… in a tube about 1/2" across and 3/4" deep a little dude w/ what looks like an orange hardhat w/ two eye stalks pops out, he puts out these two little arms that look like they have brown SPIRALED featherdusters on them… what is THAT about?! ---
