I've read about them, never used them.

do I just get yarn from the fabric store? I wonder if there are
chemicals used in the yarn preparation that would be harmful to the
fish.
==================
I used green and brown knitting yarn from Wally*World one year when I didn't
have enough hornwart to go around. Rinse it well before using. It didn't
harm anything. I wrapped it around cheap dowels from Home Depot.
