If I recall correctly we got the Crenuchus from near Santa Isabel do Rio Negro. The ones from the trade were labelled as coming from Venezuela. See http://www.aquariumglaser.com/en/archiv.php?news_id=679. The upper Rio Negro and Orinoco are joined, so many species are shared between the two. There's only one described species of Crenuchus (C. spilurus), but due to the wide distribution and variation, I'd imagine it's a complex of species.

thanks for the link and the info, the ones in the link look pretty skinny, they are one of my favourite tetras, a very cool tetra that thinks it is an apistogramma!

Hi,

I noticed that too. Perhaps the cory people can suggest a better match?
the imported specimen of "Aspidoras" pauciradiatus all originate from Rio Negro region as far as I know.
It is not clear if the type locality is correct, it seems that no "Aspidoras" pauciradiatus can be found there.

The cory that you caught is what we aquaristists consider to be "Aspidoras" pauciradiatus although it is more than doubtful that it is really an Aspidoras species.

Cheers,

Great information! Nice to see those species. Some of them are not listed at fishbase and mongabay. Nice to see the Tetragonopterus argenteus and Aequidens Diadema / Pallidus.
