Rio Negro

Post by racoll »

Recent collecting trip to the upper Rio Negro near São Gabriel da Cachoeira, Brazil. Again, we weren't targeting catfishes, but a few turned up along the way.

Very interesting doradid. Almost looks like a Chimeara. Any ideas?

This was a nice find. Caught with bare hands, snorkelling. Very long black barbels and really striking colour. Syntopic with Pterophyllum, and .

? Very nice!

. Bumped into a fisherman wandering up the road with his catch at the end of the day, so we stopped to have a look. Nearly had a seizure when I saw this. Was still alive too!

There's something really nice about collecting aquarium favourites in the wild. I think I remember @Jools saying the same thing about wild zebra danios?

Now, here's a few we bought from traders in Barcelos. I think some of them came from the Rio Demini.

Very nice. A. pauciradiatus is a "long way from home". Nice Pim, whichever it is.

I noticed that too. Perhaps the cory people can suggest a better match?

Interestingly, according to our distribution data, there are no Aspidoras in Rio Negro.

Like for the Sturisoma, I'm not saying it's wrong, just a little surprised about the apparent wide distribution.

I agree on both counts, was my gut thought before I read HH's view. sp. "Rio Negro"?

Bugger. Only collected three, I think. They appeared to quite abundant at first, but suddenly all disappeared when the full moon rose (although it may have been more to do with me splashing my net about all over the place and shining lights).

It came out of the gills of a , apparently.

I checked the description, and I don't think it's that one. looks like a better match, I think.

Actually, not if you look closely. have spatulate (spoon shaped) teeth, which is why scientists consider them to be closely related to . have strongly bicuspid (fork shaped) teeth.

Any info on what it looked like where you found it? Aside from the one picture in the clog there isn't much on the specific areas where they are found.

Yes, it is , although it's possible there's some variation in that species. It has a very wide distribution. Most in the trade come from Peru I think.

I don't have photos I'm afraid, but was caught at the edge of a lake, by a grassy area where fishermen keep their boats. It was among tree roots in shallow water (<1m), along with Pterophyllum (angelfish), and . Water was very black, and warm.

fantastic photos and you have answered one of my questions with them! I wondered where that form (maybe species?) of Crenuchus spilurus was found, if was offered for sale here last year, but no catch location

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!

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.
