The best way to feed our live blackworms to your fish is to use a cone feeder. After rinsing, put some live worms into the cone feeder and float it in your tank. This allows your fish time to enjoy the worms before they sink to the bottom of the tank and into the substrate.
My fish (loaches, barbs and ghost knife fish) just love your dried
black worms. I used to use fresh or frozen blood worms, but I find my fish get way more excited for much longer about the blackworms.
