Richard- Thanks so much for your insight. My tank is not totally covered (though my lighting does a pretty good job of preventing escape by covering the entire opening on the top about 5" above the surface, plus I have an 8" facade/cap around the top of the tank.) I might try a tilefish one day based on your advice. I think I will go with the neon dottyback right now. With your experience and after studying more it seems their aggression is manageable in bigger tanks.

Thanks again for your time.
