A wtt would be white tank treatment fish. They get light when they are in white tanks. If it was a platinum I don't think the spot behind the gill plate would be there or as visible. Also I think the fins wouldn't be as pink. If I remember correct the plat aros have more of a "powder coat" instead of shining coat like that fish. I am think more of a high shine aro. The high shine has the crime silver scales brighter and the go higher in the body sometimes on the back. At least that is what I recall the difference is. I am not an expert on those morphs, but from the pics that I have seen that is what I think. I know hao has had a high shine silver aro. I have not, but I have had many many aros.
