It looks just like a little tomato clown I had a couple of weeks ago. I assume that, from the picture, it's about 2'' or so? If that is the case it has a really dark beautiful color for being so small. Typically tomato clowns start out with a bright orange coloration and darken up with age.
From pictures 2 and 3 it looks to sill have a sliver of a second white stripe towards the tail. Juviniles start with multiple stripes which fade away with age. This leaves the prominent white stripe behind the "face" of the clown.
Beautiful fish corbett_n!
Hope this helps,
