Live food for Lions?

[danny zubot]

Well, my white line lionfish really hasn't taken to eating in my tank since I bought it 2 weeks ago. I've seen it eat two or three times and tried various techniques such as feeding at night, and a form of nursing I like to call Turkey basting! I would like to try some form of live food, is there a certain type I can feed it that is cost effective and known to work well?
I have fed lions small fresh water fish before but only in a nano tank where the lion was the only fish. I would hate to turn my clowns and wrasses on to live food so I would appriciate any advise about this issue.
