The hard tubed worms I've seen now and then at Texas Tropical are in the $60 range, including the one I saw yesterday. Maybe I'm checking the wrong places; but anyway I will need to hold off a few months before buying another worm to make sure they all are eating plenty. I think my tank in especially nutrient rich, so the jumbo feather duster I have had has been growing and thriving; looks huge in my 30 gal.
