what is it

[jerseydiver]

any help IDing this critter would be greatly appreciated. Its definitely getting bigger and it seems to spin some sort of web that it retracts when I feed phytoplankton or cyclopeeze. Is it bad?

Sorry I can't help on the ID, but welcome to RS!

Welcome to RS!

Is the "head"/where the web comes out on the lower right? It is possible that it is a vermetid snail. Or the end where the web comes out, do you see two antennae protruding?

Here is a link to an article about them: Worms that aint...Vermetid Snails in Marine Aquaria

Hey NaH20, I think you've solved our riddle! All indications are that you are right and it is a snail. The link listed a snail that excreted a mucas net and would reel it in from time to time. Thanks again, this forum is a godsend!
