Now you can utilize your Mag-Float (glass or acrylic model) to feed you saltwater fish. Simply attach the Mag-Clip to you Mag-Float (S & M Glass/Acrylic Mag-Float sizes) and it becomes a feeding Clip. Place a piece of seaweed, spinach and other vegetable foods in between the clip and the Mag-Float inner part. It will keep it in place. Enjoy watching your fish indulge!
