Another fish question

[marie]

Ok Anthony et al, my tank is doing fantastically well and I hate to mess with it but it needs a few fish that swim out in the open. The only fish my guests ever see is the achilles. The foxface mostly hangs out in one spot looking like a bloated pig, the regal angel sneaks around chowing down on corals when no one is looking, My 2 dottybacks are too busy playing house to worry about being seen and the 6 cardinals never move from the same spot.
So I was thinking 3 anthias or 5 green chromis. Should I just carry on with what I've got (don't mess with a good thing)? or should i get the anthias? what kind of anthias are the best? Would the chromis be better because they are less of a bioload?
I did discover that i'm emotionally attached to my skimmer so it is back on the tank again. I just wasn't comfortable without it otherwise I wouldn't even consider any more fish


*edit* If I get more fish on everyones recommendation and the tank crashes after... I get to blame you guys
