I have heard from other fish keepers about Bloodworms to Frenchy, I have actually thought about not replacing the next lot that we currently have, and moving onto other alternatives... We bought a whole heap in bulk, so thought we would use them up, however, as said before my African Cichlids don't get them.
I agree with Frenchy, suggesting the use of them to others isn't what I would do either, there are other alternatives out there and with the thoughts and information given against Bloodworms, I would definately be encouraging other foods over Bloodworms anyday IMO
