I use this treat as a supplement to another food source (pellets), and my lone male Betta literally tears into it with evident relish! As instructed, I usually give just a few times per week. I don't tap an amount into the tank as this is often just too much. I pinch off a small amount with my fingers and then scrub my hands well; also, my hands are clean to begin with. As I write this, I came to the belated idea of using tweezers to pick up the worms. Better late than never. I hope your fish enjoys this wonderful product!
