Great! It is a great feeling when you hand feed your fish.Word of Caution! A lionfish's sting is very painful to people and can result in breathing difficulties and nausea, although it generally does not cause death. If you get hit run as hot of water you can stand over the spot for at least 15mins. to 30 mins..It will break up the protein poison.If you have trouble breathing go to hospital.If you do not have to go to the hospital put Adolph's Meat Tenderizer (brand Lawry's by Far Away Foods) on it . It will draw out the protein poison.
