billyxth Posted May 12, 2008 Share Posted May 12, 2008 Hey, my bro and I noticed today a bunch of REALLY small shell looking things on the glass around our tank. They're really small like 1cm or less. I was lucky enough to get my camera to focus on one of them quite nicely and be able to see some detail...from what I see it looks like a snail shell w/ filter feeding feather tentacles... We've have like 5 or 6 "batches" of Snail eggs over about 3-4 week period and haven't noticed any hatch but they'd disappear, could these be the small snail babies? They're from the Cerith snails we think. Anyway, any help would be greatly appreciated. Thanks. Link to comment
Mischeif Nite Posted May 12, 2008 Share Posted May 12, 2008 "Spiroid" I'm pretty sure they're called. I believe in the one of the forums there's a great critter identifying thread. Tons of great info Link to comment

c est ma Posted May 13, 2008 Share Posted May 13, 2008 serpulids. They are calcareous tube worms (under serpulidae in the link):http://home2.pacific.net.ph/%7Esweetyummy42/hitchworms.html http://www.wetwebmedia.com/polychaetes.htm Wow, that's the first time I've noticed that Chuck Raabe has Spirorbis listed under Serpulidae. I had always learned that they were in their own family, the Spirorbidae, which, along with the Serpulidae and the Sabellidae, comprised the 3 main groups of feather dusters that hitchhike into our tanks. Has the nomenclature changed, or is Chuck possibly wrong?! A few pages that show Spirorbidae: http://www.xtalworld.com/Aquarium/hitchfaq.htm http://www.saltwaterfish.com/vb/showthread.php?t=163864 And for that matter, Chuck has Flabelligerids listed under Serpulidae, and I'd thought they were in their own family, as well. http://www.marinespecies.org/aphia.php?p=t...ails&id=976 http://www.marinespecies.org/aphia.php?p=t...ails&id=989 I think we need to drop Chuck a line... --Diane Link to comment

c est ma Posted May 13, 2008 Share Posted May 13, 2008 Thrilled as I was to have Helfrich's Chick put together that thread, it doesn't really address the family nomenclature... IME, they are genus Spirorbis, family Spirorbidae; and in general, one of 3 types of "feather duster worms." --Diane Link to comment
