jimmyrickson,
Talk about over reaction...Read my post again, I said that the owner advise me not to purchase a more expensive fish that was only eating live food, instead he recommend this fish. In other words, I did not feel like I was being taken or duped by the lfs owner. Keep your unwanted, off-topic tips to yourself.
On a separate note, thanks to all who provided me with helpful information. My dwarf-lion is doing great. He eats frozen krill like crazy. He will only eat the shrimp with the heads left on. I think he likes to look his prey in the eyes before inhaling it.
