Calloplesiops altivelis, another of my favorite fish. Yes they are docile and shy. They can be a bit difficult to get over to frozen food but I've never lost one that way. Come to think of it, I've never lost one.
Currently, I have two Marine Bettas in my 135 with terrific results. Mostly they ignore each other unless they are passing. Then they pause, display their fins wide and pass slowly by. It's real cool. I have yet to have camera in hand when they do this so can't show you that but here's a pic of one.
They are definitely camera shy, too.
Great fish though.
