They are the silver ones (silver dat, not to be confused with Silver Tiger, ST) with the 2 dots instead of a bar at the rear of the caudal peduncle. I'm not sure what ones they are at F-P. I think they are AT's since they were in a brackish tank, but mine has been fine in a FW tank, you will just have to acclimate it a lot longer since it came from a brackish tank. There's one other brackish sp., but I can't remember off the top of my head. I didn't really look at them well. I think they were about 2, maybe 3 inches. The brackish tank is the one that faces the desk.
edit: NGT are the other "brackish" ones. they are VERY easy to tell apart from the silver dat (a.k.a. american tiger or AT)
ST = Siamese Tiger (not Silver Tiger)
aka widebarAT = American Tiger (silver dat) - brackish one
IT = Indonesian Tiger
NTT = Northern Thai Tiger
NGT = New Guinean Tiger
AT&T = telephone company

BTW, nice NTT. Once he settle in, you'll love his color
I wonder why both places keep them in brackish tanks...Did you by any chance ask? I didn't know Todd's was out but I did call Fish Palace cause I thought if they had silvers or something different I would get one. No such luck though.
Post some pics.
