I also had a big 'ol pink worm. I pulled him out while vacuuming the cc. I stuck him in a container to take to the lfs for an id but they were closed and I didn't feel like keeping this thing on my kitchen counter over the weekend (ours is closed sunday and monday). Mine was huge (a good 2 inches) but no bristes, more like a common earth worm except pink. Haven't seen anymore since then.
You just never know what you'll find in a tank with lr in it!!! Or never know what it is that you find !!lol
