Oh yeah,I say ST as well but it looks to have rather thin bars compared others that I have seen.It's an interesting look and I've seen very wide bars and here is an example of an opposite extreme.
Reason (based on the stripes):
3 is too narrow at the top and too wide at the bottom of the fish (does not form the classic V)
5 and 6 should be connected and form a saddle at the root of the tail
7 shold be central on the tail (where 6 is on yours) and not be connected with the rays of the caudale
