respectfully I disagree. Lion fish are a sit and wait predator and thus have a slow metabolism. In reality once every 3 days is more than enough. Here's the lion fish info sheet that I think you should read: http://www.reefkeeping.com/issues/2002-11/fm/feature/
My dwarf fuzzy will get some food when I feed my other fish however I target feed him max twice a week and I have had him for 4 months now with great success. A big part of this is a varied diet. If the fish eats the same food all the time they are susceptible to 'lock jaw'.
Just thought I'd share what has worked for me.
