I don't see the stripe going into the tail, to me it looks like it's not even close to the end of the caudal penduncle. It could be I'm not seeing it well enough or just because the fish is stressed. It seems more pink than bronze too, stress or age or species?
We had rabauti maybe 30+ years ago & while ours had rounded noses maybe not quite like yours AFAIR. Its tail seems longer too. Does it seem adult size? Rabauti are a bit smaller than some corys.
Maybe wait until it adjusts to your tank, then you might be better able to tell. With more pics of course, we want to see!
