Please help with fish ID

Ok, so I was watching a reef video on youtube, and it had some really pretty blue bodied fish with a red tail. I think it may be just some sort of variant of chrysiptera cyanea (blue damsel), but wanted to see if anyone here knew more. The link to the video I was watching is below, and the specific fish is shown by itself around the 4:57 mark:
