How often are you feeding? My guess is you are feeding every day or so. This won't work to get him off live food because he's not hungry enough to try frozen. Starve the tank for several days ... maybe 4 or 5. Fish in the wild don't eat daily, so no worries. At that point, I'll bet your lion takes frozen food. You may have to make it "look alive" at first. Use a large piece of something...maybe Krill. Hold it in your fingers and stick it into the tank, with your fingertips just below the surface of the water. Wiggle it around and get the lion's attention. He'll most likely take it right from your fingers. Lion's aren't shy by any stretch. If this idea makes you squeamish, then use stainless steel kitchen tongs.
Just don't stick your whole hand in.... he's not likely to sting you, but you could brush against the spines by accident this way. If he's taking food from you, his spines will be out of the way.
(It's just a thought question) I have read that some people lionfish want eat frozen foods...so i was just wondering what live foods you could feed them, because I have always heard that live foods are not good for them but yet still they eat live things in the ocean
