    Hi guys. I noticed these white Shell like creatures behind my return pipe and in the overflow box. They also seem to be multiplying. What are these and are they good or bad?

    Tube Worms??? But they look like miniature sun dial snails. And they have hard shells. I'm scared to clean the glass coz their shells can scratch it. What should I do?

    They are harmless, all tanks have them and no they not sundials. You will only find sundials on your zoas, and they look distinctly different

    Yep that's true. I had a sundial on my zoas a while back. The shape of the shells are similar though.

    I also have them on my glass. They have a spiral shape but I noticed that they have little fans, so I just left them so they can help to clean my water :)

    Do you have Nerite or Turbo Snails in your tank?

    I doubt the ones I have are snails. Took a good look at them and their bodies spiral into their shells and are red in colour. So I guess they are worms. They Multiply quite fast. And the majority of them are in my overflow box, and very few behind the overflow pipe. The pic in post 1 was taken a while back. There are 100's more than that now and seem to live where there is no light or flow.

    Cool worms, will be filter feeders.

    Anyway Nerita eggs do not hatch easily. Something to do with being exposed at times due to tides.

    Snail Eggs. Just scrape them off. No harm.

    Most likely they are either vermatid snails (yes, snails... but unlike normal snails, these guys are sessile, and do not move once attached to a rock or other object) or small Polychaeta feather duster worms, perhaps Spirorbits or Serpula vermicularis.

    Either way, they are filter feeders, and generally good to have in your tank.
