Fish identification

[Ortizdrz]

So while watching reef tank tours I noticed a fish thats caught my attention and haven't seen before maybe tall can help me identify. Purple seems purplish with yellow stripe down the middle

After much google research I think ive found the fish. It's a small toothed whiptail

Cool looking fish. I looked it up. they lose their stripes as they get older and they get big, over foot long.
