I fed mine ghost shrimp in the beginning, then weaned over to frozen krill and silversides. I fed her about 5 ghost shrimp right before I had to leave town for 4 days. When I got back, I tried thawing a few krill. She went for it!!! Don't believe the LFS that lions cannot be converted to frozen food. A ton of people on this site have done it very successfully. Also, try withholding food for 2 to 3 days. If the lion is hungry, it WILL eat. My LFS told me that a lion will starve itself to death if you don't provide live food only:hilarious Yeah, right!!
