white tubes?

[grandmarm]

we have these white tubes growing out from under rocks everywhere. also have small I guess white worms. any help about what they are - and if I should just leave them -
We have a 90 gallon reef tank with a blue hippo, yellow tang, royal gamma, clowns, goby, and a green star.
as always thanks for you information and help.

Spirobid worms (sp) they are fine, not to worry. How old is your tank? these are usually associated with new tanks

tank is about 2 years old = the worms started showing up about 6 months ago.
should i pull some of the tubes out?
thanks for your help

The white tubes are feather dusters. Perfectly harmless! It's a sign the tank is maturing and healthy.

are the small white things small curly q's about 1/8" kinda looking like pig tails or are they long with small feather dusters sticking out? Either way they are OK
