What worms would you recommend for a CBB? I’ve been feeding a small amount of dried blood worms/flakes/pellets mix twice a day and in between my fish get a variety of frozen foods, clams, mussels, shrimp, cockels etc. my CBB won’t take food from the water column that I can see but it does forage the rocks all day every day, is this a good sign? Could it be getting food that dropped onto the rocks?
