I assume that black worms >cannot be frozen as can bloodworms and brine shrimp. *No* really rich food can be safely frozen after it dies. Blood worms and (possibly) brine shrimp will do the exact same things to your fish, if not alive when frozen. That's a real problem with some of the off-brand SE-Asian frozen products. Several are known to be lethal, for the blood worms are rotting when frozen. Try eating a dead-before-cooking-or-freezing lobster and find out how you feel. ;-) Bacteria simply attack too quickly for safety.
