I have a Coral Beauty in mine, which I love!  She has been reef safe so far.  I had a darth maul that disappeared two days after I got it, but I can't prove it was her. 

  I have a completely full frag rack that has done great for months without an issue.  I also have a spotted mandarin which is gorgeous.  You have to either have a very established tank, refugium or dose pods so you can keep a pod population in tact.  I put a good amount of red (dragon's breath?) macro algae in the tank.  I like the look and it stays fairly infested with pods (just check at night).  I have a pair of clowns, black and true perc.  Anyhow, lots of options for beautiful fish.  I think you're daughter would be fascinated with any of them...ESPECIALLY if you could get clowns that host a coral.
