You probably know this, but I get them from Tropical Isle. I also got them once at Uncle Neds Fish Factory but he mentioned to me they won't get them in the summer so not sure they'll have them now. Finally I do have some small quantity of live worms left (very small amount, semi old) and a bag of freeze dried blackworm cubes that I've been switching my butterfly to.. if you are in a pinch you can have them but you gotta come to worcester!
