[cory green stripe] Where does it come from exactly?

[C-Magnier]

Hello,

I'd get 4 cory, identified as "green stripe".

Just for pleasure :











I'would like to know the geografical origine of this fish...
I thought it was Rio Nanay (Peru) but someone tells me what it's Rio Ucayali, near Pucallpa (????).

Can someone help me please

thank's!

Let's start with "I don't know the answer to the question".

Both Rio Nanay and Rio Ucayali are fairly popular regions to collect fish for the trade in Peru. They aren't very far apart either (relatively speaking). Nanay is a "left-hand" river on the upper Amazon, and Ucayali is just slightly further up on the right-hand side of the Amazon, perhaps 50 km or so furter upstream.

Both rivers are fairly long, Nanay looks like it's in the region of 200km long, and Ucayali covers a linear distance of about 500km (but the river curves like snake across the map, so if you follow one edge it's probably 800-1000 km of river in that distance).

Fish originating from either river would most likely export out of Iquitos, but there are several airports along the Ucayali further up-river, near to Pucullpa, near Bolognesi and near Atalaya.

And it may of course be that the same or similar fish exists in both rivers.

The exact location of these fish is not known. They command a good price in the market place and because of this collectors are very reluctant to reveal there collecting locations.

Hi Mats!

Let's start with "I don't know the answer to the question".

It's a bad start

Nanay is a "left-hand" river on the upper Amazon, and Ucayali is just slightly further up on the right-hand side of the Amazon, perhaps 50 km or so furter upstream.

I have shearch for information for both river.
I can't resume it, it will take me 2 days .
But Rio Ucayali and Rio Nanay are very different, that's why I ask some precisions. Nanay, black water, Ucayali essentialy white water.
Can I keep the fishes around pH6?
The biggest probleme is temperature. Between 20 / 24 °C.
For Rio Nanay why not, but for Rio Ucayali near Pucallpa...

And it may of course be that the same or similar fish exists in both rivers.

May be.
I'll put the fishes in specific tank asap, and I don't know exactly what are their needs... Impossible to follow C.aeneus data, Yann tells me that the "green stripe" is more apparented to C.melanotaenia, It seems a better exemple.

I'm not surprised.
This morning I have a look to our Aqualog. For the "green streep", very large distribution (Ecuador, Colombia, Peru, Brasil...) It remembers me an other cory that I keep (sp black). Surprise! the next picture is a sp black, and the distribution is exactly the same.

The essentiel is to find the good water parameters for fishes, the rest...

thank's a lot.

I've bred these green things at 24 degrees celcius, pH 7 and conductivity around 100 microsiemens/cm.

The lay very large eggs, around 2 mm. in size and not very many.

They seem very happy in plain rainwater
