Just like any food, if these frozen bloodworms were allowed to defrost and
then refreeze bad things can happen.

on 2 seperate occasions bloodworms have almost instantly made my tiger
barbs
sick. one would not eat after the BW's for 3 or 4 weeks, he is only now
coming back to normal, the other seemed to instantly develop paralysis on
1
side of his body only being able to swim to 1 side, he is getting better
too.
could it be "bad frozen bloodworms" or has anyone had any similar
experiences?
