This list is looking better. I had a six line wrasse and really enjoyed it. It wasn't aggressive towards an of my other livestock.
The Royal gramma on the other hand was a PITA. He was one of my favorite fish, but after a year, he grew a little and was bullying absolutely everyone, even fish bigger than him. He wasn't really all that large when he started getting aggressive either. I eventually had to tear down the entire tank to get him out and just donated it to my local LFS. As much as I love the royal gramma, I'd never take that risk again.
