Is this a Bristol worm? I've never seeing one so hairy????
I was noticing what looked like hair swaying out of the sand the other day, thought it was algae and gave it a suck with the baster I use for feeding and got nothing?
Then noticed it again few inches over a couple days later and that the hairs don't always flow with the water
So I decide to give the sand a suck in that spot while I was changing water this morning.
This is what I found in the bottom of my bucket, I cleaned it up to get a picture, it was in a sand/web blob?
