    Little white specs...

    I was cleaning the sandbed and tank up last night and noticed tons of little white specs on the back wall of the aquarium and on he calking strips in the corner. They were fairly hard to scrub off. Kind of white, hard and either round or swirly design.

    Does anyone know what these are?

    I beleive they are a type of feather duster worm. They are okay and you can leave them. They are a sign of a healthy tank.

    They may be Spirorbid Worms. I have them all over my tank and are reef safe. You can just scrape them off if you don't like the look of them. There's a picture at

    Does this look like what you have?

    Yes I'm pretty sure that's what they are, and they seem to re-produce like mad!

    Any words on them?

    I guess they are harmles..

    After an hour of Googling I got this from http://www.reeffrontiers.com



    Spirorbid polychaetes are harmless tightly coiled white spirals that are no larger than a few mm in diameter. They appear on the glass, pumps, in sumps, etc. These common critters are most often seen in new aquariums, and may have periodic population growth depending on nutrient availability. Spirorbids usually come under control or disappear as the tank ages. They feed primarily on tiny particles in the range of bacterial floc and tiny suspended particles of organic detritus to the smaller end of cell sizes of phytoplankton.
