Thank you, I love black worms, never had any health issues with any fish, they are all fat, bright and displaying mating patterns. This is approx. year 20plus that I have only truly fed black worms as the staple. I do feed other foods so they don't get bored twice a week to all my tanks, sort of like a mix that B uses a little of this and that but the stable it black worms and always will be. I really try to feed live, I raise brine, I go the shore with a net and gather pods and small what ever gets in the net and feed that to the tank. that is what my fish really flip out for but I am not 100% trusting of everything that gets needed so I pick out the larger items in case, but knock on wood the ocean has never let me down yet.
