ID and question on feather duster

[kimbertent]

what is this floating in my tank? it looks like strings of dust?? it is all in it! i dont know if it is a good thing or a bad thing? my tank is covered all on top so i know that it cant be dust but that is exactly what it looks like...

here's some pics:

in my tank there is:
fairy wrasse
5 narssius snails
1 feather duster
3 sexy shrimp

anyone else?

Not cyanobacteria. You would see that on your sandbed or rock.

It looks lke (assuming you have no corals in the tank) the mucous web from a vermitid worm/snail. See if you can follow the trail to a calcerous tube in the liverock.

As for the featherduster... They sometimes detach their crown when they are stressed. Give it time, and it will grow a new one, but consider where it's at. Is it in a calm area? Are your water paramters good?

thank you for responding lizz

i knew it wasnt cyanobacteria.

it seems to be floating around not coing from anywehre really..i tried pulling it out and it is definitely like mucousy (if thats even a word)

i think i will be moving where my feather duster is. this is my first time having one can you tell. so what do i do with the crown that is floating around? will it die?

My guess is that it's definitley from a vermitid worm. They can be tricky to see sometimes.

You can just take the crown out and chuck it, as far as I know. Be careful when you move the duster and don't pinch too hard or damage the worm's tube.

My liverock will do that sometimes when I do a waterchange or move it out of the water for awhile. I think its small rock critters that are mad about something.
