I have many large cichlids and I feed them frozen blood worms all of the
time. I always buy my frozen foods from a major chain such as Petsmart. I
have never had any problems. Blood worms are really more suited for
carnivores rather than omnivores such as your Tiger Barbs. The blood worms
tend to stay in there systems longer and causes them to get bloat. The
staple of my carnivores cichlid's diets are frozen brine shrimp. These are
recommended more Lake Malawi omnivores rater than blood worms because of
their tendency to get Malawi Bloat. You could have gotten a bad batch of
blood worms, but most likely brine shrimp will better agree with your
omnivorous cichlids.

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?
