CC, t1 not referring to u mate.
The lower price T1 posted was maybe a year ago. Not much more or less, (I think)
So price will have gone up a bit now.
Regarding £ 2k for T1 ST, I can fully understand the high price:
It is a damn near perfect grade ST
Has all the identifiable factors of ST
And must be 24 inch long and the depth or height must be near 12 inch or more.
It could be the largest in captivity, and is still not that old for a tigerfish. So has many Years to go.
Most importantly it's the personal attachment, I know what te owner gone through to keep and raise this fish from 3 inch to it's current size.
