Guts, Guts and more Guts, you need something whole, Smelt, Shrimp etc that you can cut the guts open. From my experience, These critters( your dragon) in a closed system primally hunt off of smell. Once it associates the smell/food in your tank you should be fine. If not it will continue to smell the live fish and fish waste. This will only continue to teach it that your other fish are fair game. And by the way, I have seen first hand one of these, kill a 10" queen angel as noted before in seconds. Ddougedoug, wish you the best, these are great animals with lots of personality.
