Pointy or not seems they're all "Brasiliensis".
The ones I have now are also pointy beaked.....
I wouldn't go so far as to say all
Salminus sp. being imported are
S. brasiliensis, however from what I can glean from this forum and imports it seems the current imports are skewed toward this species. Would not be surprised if
S. franciscanus were still being imported as well, especially since they likely still constitute a majority share in total captive production.
Once I get this corydoras project sorted out I will get the ball rolling on putting together some generalized metrics for further evaluating and diagnosing these species beyond Chicxulubs great guide. For now the only concrete diagnostic I can provide is dentition, but unfortunately that is only useful with sub-adult/adult animals.
Also I would like to apologize for only making more of a mess for positively ID'ing these animals haha I know its been a bit of a rollercoaster for all of us! So it goes with taxonomy I suppose.
Cheers,
Andrew
