The Feeding Prong is an excellent tool for close-up feeding of Lionfish, Stonefish, Groupers, Oscars and other predators. Simply skewer Lance Fish or Krill Superba with this “invisible” acrylic prong and use a “wiggle-action” to trigger the feeding response. This is an ideal tool to wean fish off live food. Best used for feeding carnivorous fish by attaching Lance Fish, Krill Superba, chunks of squid etc. for feeding of predators.
