Need some help with this one

[Renegade]

I third the vermatid snail. if you look at the picture right below the coral you can see were the webs originate. That small round "tube" is the vermatid snail.

after feed the tank you should be able to see the snail pulling the web back into his home to feed off it.

joes juice or some kalk (little r/o water) into the tube also works
