Hogging the HH thread.... Another critter

[DaveR11]

I was working in the sump today and took a closer look at the white dots on the glass with a hand lens and realised they weren't dirt. There are loads on the glass in the left hand side of the sump where I have my macro algae. They are also on the back wall of the tank. My guess is Spirorbid worms.



The Internet tells me they are reef safe.....

Spirorbid worms. filter feeders. harmless. Probably great for a sump area to assist in filtration.

Thanks for the confirmation Oxy.
