Hey team,

Got little white 'curly' things, almost doughnut shaped on the back of the tank. They don't move, and are only about 1mm in diameter.. Any ideas what they are? No photos sorry..

if there like that they would be spirorbid worms

Thanks Wilson - that looks like them!!

no problem

Onya! Cheers! Watch that soft drink, fella!

oh yeah, he must be some sort of sugar holding camel haha, 3litres or pepsi in organism! thats a lot of pepsi haha

what are they?

Little hard white spirals on your rock and glass causing confusion? When you look real close, do they have little feathers sticking out the end? Congrats, you got yourself some spirorbid worms. These little guys live in their calcareous shells and filter feed. They are harmless additions to your reef.

ohhhhhhhhhhhhhhhhhhh

Probably beneficial as well

yea there small filter feeders
