What are these spots

[Charlie G]

Hi all ,

I have a question regarding a 10 gallon tank I put together my display tank is a 32 gallon Biocube. I had a couple of 10 gallon tanks at home and need to remove cleaner shrimp from my display tank. The tank is now about 6 months old.

Early on I noticed these white spots or calcifications developing around the tank. I thought it may be some form of algae like corralline (but white) but I’m really not sure.

Can anyone please identify this for me. My display tank is 2 years old and I don’t have that in the DT.

Is it something I should be concerned about or need to remove?

Any information/guidance is greatly appreciated.

Thanks.

Spirobid worms. They will go away in time or just scrape them off.

Great. Thank you.

Spirorbid worms, harmless filter feeders that, as you observed, spread rather quickly

Yes. It was quick.
I guess just scrape?
