worms?

[martianarts]

they look like worms that had dug tunnels under the live sand. is this normal? also out of no where two feather dusters appeared on my live rock.
any input would be greatly appreciated

Yep worm tunnels are a good sign the the critters in a sand bed are doing their job! eather dusters poping up show the tank is maturing and should be doing well!

I can see tunnels in my sand as well... kind of like tunnels in those pet ant farm things you see on tv and such. I took a pic once and it was identified as a bristleworm tunnel. Sounds like what you are describing to me.
