Also, Lionfish are predators, they need to think that they are hunting their food down, one thing they look for it the eye. I have my lion eating mysis, but won't touch smelt or formula 1 at all. This is the process I went through to 'ween' my lion. I bought 20 ghost shrimp for a buck, and I put most of them in, and the lion ate almost all of them. Then a week later, I bought some mysis shrimp, defrosted them, and he wolfed them down. For me it wasn't hard at all.
