We have had tinfoil barbs come to us as rescues over the past decade, perhaps a dozen or more. I am not versed to tell the difference between the two most common species (or so I am told by Jeff Rapps) - the Barbonymus altus (red-tailed tinfoil) and Barbonymus schwanenfeldii (tinfoil barb) - because I have never looked into it... because they are not a giant fish and I discriminate between fish according to my pet "size fetish", of course...
Nice thread by Rafini this is: https://www.monsterfishkeepers.com/...-barbus-schwanefeldi-and-barbus-altus.513210/ It states that altus grow smaller 8"-10" and schwanenfeldii bigger to 14"+ and the latter sport much more prominent black stripes in their tail fin.
The tinfoils appear to be rather underrated in our circles. However, when they are large and in a large school, they are striking, even I can appreciate it.
None of ours have appeared to ever exceed a foot. Many of ours fell prey to African tigerfish, it would appear, in one of the 4500 gal, so the remaining 4-5 have been transferred to a 240 gal and then, after a year or so, into our 25,000 gal cyprinid exhibit.
Recently we lost one of the bigger ones to seemingly natural causes. It's been with us about 5 years, having reached 13":
