Live Rock question.

[TamDuncan]

Does anyone know what these white swirly things are on my live rock? They never seem to move and I was wondering are they living and are then something that is normal or ok for my tank? Thank you

Filter feeders of one type or another. Only one to be concerned about is the first, which is a vermetid snail. They throw a net out to capture food. This net, from the large ones, can irritate and kill coral.

Well, so far I do not have coral in my tank but are they harmful to my fish and how do I get rid of them? I need to get a better zoom so I can see them better. Thank you for your help in identifying them, I couldn't find anything online to identify them myself, so thank you ?
