I can't believe the looks of the large one in the bottom pic...If I didn't know any better and just made a very quick glance at it...I would have thought it was a Splake! The ones we used to catch in Georgian bay looked just like that (silver and nice and plump) only with spots instead of stripes.
The large female had very dark markings on the top but faded quickly on the sides, I'm always surprised at the difference in color and patterns in tigers.
