What is this white stuff on wall?

[uhu17]

HI! I'm new to this discussion board. I've been trying to check the website for the tiny white circular-shaped (looks like the end of gecko tail shape) stuff that is spread out on my aquarium wall. Anyone here knows what it is?

I've tried to take a picture using DSC-50, I couldn't take a clear picture of it.

BTW, this stuff isn't on "WTH is this" FAQ.

Thanks,
Karl

Those are little feather duster worms

So, those are little feather duster worms? Interesting...

I assumed they would grow on rocks, not on the aquarium walls?

 

[uhu17]

Yes! They are the ones that I was talking about. So, that is one mystery solved.

I'll be checking more information on this type of animal.

Thanks!

This is from the Hitchhikers FAQ:

On the glass of my tank, I can see small, white coils that are about 2mm across and have tiny hairs sticking out. What are these guys?


This is probably yet another tube-dwelling polychaete from the Family Spirorbidae. It is yet another harmless filter-feeder that is common in reef aquaria. It is common for these worms to inhabit areas of high water flow, including your tank's plumbing. They readily reproduce via sexual means and often spread throughout the tank, and can generally be considered a sign of a healthy maturing tank.

I wanted to make the final input here

Those are definitely very small feather duster worms belonging to the family Spirorbidae.

Thanks.
