We had a talk about this at the fish store yesterday. Puffer breeder, store owner, discuss breeder and myself. Bettas not the only ones that have been effected. No problems reported with SFBB Freshwater Frenzy, lord how young bettas love this product or other frozens. However there are many reports of parasite issues with the bloodworms. Not all batches or all cubes within a package even, but every once in awhile a problem is getting through the system. I have no scientific proof but lots and lots of hearsay from other aquarists.
