New guy question?

[twindad12]

I have just received a 30gallon tank from a friend of mine who took amazing care of it. Everything seems to be doing excellent from the move 2 weeks ago. My question is that I have these little white tubes coming out of my sand with little string-like stuff coming out of them. What is this and is it good/bad for my tank? Thanks

I have them in my tank all the time it has been up over 3 years they are harmless I do not remember what they are called but they are live critters just like the pods you can only see with a magnifying glass reef nut would know almost all know the name but not me oops
