OK here is the Facts on feeding a lionfish.
Goldfish are the worst feeders for a lionfish. They are high in fats and do not have the neccesary nutrients for a lion. Ghost Shrimp are the best live feeders (unless you live by the ocean, then you can catch marine minnows or shrimp.) Gut load these shrimp and feed them to your lion. Depending on the size of your lion determines how much you should feed him.
If your lion is:
1-5 inches--feed it everyday about 1-3 ghost shrimp daily. Try not to feed all at once. Space it out in the day.
6-11 inches-- feed it every 2 days about 1-4 ghost shrimp.
12-max inches-- feed it every 3 days about 1-5 ghost shrimp.
After the lion gets settled in his new home start trying to wean it over. Silversides and mysis shrimp ought to work. Impale the food with a piece of rigid airline tubing or a feeding stick and wiggle it so it looks alive. Keep trying until it accepts prepared foods.
Hope this helps.
