My big T1 Female doesn't have any white at the upper tip go back to my thread and look for yourself. I don't remember any of them having that white on them unless their tail got bitten or something.
In regards to That pic off rapps site the tapajos is at that stage when at least I can't tell if it'll become a T1 or T2... IMO it's just slight tail damage I don't think rapps sits on his fish for too long since he sells them so fast so they sometimes have slight shipping damage when they come in from Brazil I think my old T1s and T2 had a bit of that when he came in too
