help me with a possible worm problem

I think I have a bunch of what you are talking about, and they seem to do no harm. There were like 3-4 attached to a frag Joel sold me about a year ago and he didn't seem worried so I didn't bother to ask about them. I will try and take a pic and post it here.

 

Here it is. Sorry about the sort of fuzzy pic. Said frag disk is in the corner of the tank so I couldn't center it either.

Obviously the red circled things are what I am thinking you are talking about. There are more on the left but I couldn't get those in frame since it is right at the corner of the tank.

 

Are they extending a long web like strand, especially around feedings? If so, they are vermetid snails.

 

Mine do something like that. Not around feedings per se. Don't really pay much attention honestly since they don't seem to bother anything /DesktopModules/ActiveForums/themes/_default/emoticons/tongue.gif

 

What you have is not a worm problem, it's a snail problem. They start with a V, but forgot what they are called.

The best way is to manually remove them. If you follow the stem back down, they curl up where the shell is round. The best way I found to remove them is get bone cutters or
something of the like and snip them off. They'll spread like wild fire if left alone. The few you see means there's many more you don't.

 

vermitids, that's what they are called.

 

So does that mean they are bad?

 

I am by far no way to say yes or no, it's argued if they are or aren't.
