Corydoras venezuela

[Manoah]

Hi there,

Does anyone, maybe shane, have fotos of the habitat of the location corydoras schultzei black lives in the llanos?

[Ron.H]

corydoras schultzi black is a man made variant. they do not exist in the wild

Exactly.

But in shanes venezuela dairy he tells about catching these in the llanos. So??

No, he doesn't, he talks about this:

Corydoras(ln7) sp`llanos`

. Don't worry, you are not the first to be confused by this!

Oh tanks,

Thats probably a darker variation of the c.Schultzei? Or c.venezuelanus?

C. schultzei is from a completely different river system in Peru.

C. venezuelanus is restricted to the Tuy and Valencia basins.

C. sp. llanos is found south of the Andes in the northern llanos of Venezuela. As one travels further south in the llanos it disappears and is replaced by C. concolor.

I am unsure if it is more closely related to C. venezuelanus or if its just a much darker northern population of C. concolor. When first caught they are a bright, metallic green reminiscent of wild C. (Brochis) splendens. After they settle in the metallic sheen disappears and the fish become dark in coloration.

The current C. venezuelanus available in the hobby was taken from a population near Bejuma and "imported" to Germany in baby food jars in 2000. I do not know the specific German aquarist that received this one time "import" but they bred them and the fish spread through the hobby. There are now even several deformed versions available selling under various trade names such as "Orange sailfin" and "red sailfin."

I do not believe C. sp llanos has ever been taken outside of Venezuela.

Thank you so much. So corydoras concolor does occur in the llanos? I tought more south near amazonas state in venezuela. How would its habitat look like? Plants?

[Shane]

That is the thing with holotype locations. They represent a single point of discovery only. In the case of C. concolor the ho!otype location is actually the very southern edge of their range in the wild.

For a llanos tank it all depends if you want to recreate the wet season or dry season. Wet season would be aquatic or emersed plants replicating a flooded area of grassland. Dry season would be no plants with leaf litter over a sand substrate and driftwood representing downed trees and roots exposed from the river bank.

Well i am making a morichal. With little plants. Only a bit of najas sp. I already have some c.aeneus, c.brevirostris and a few cardinals. Morichals maintain their water all year round so plants would be possible i guess in a dry season set up. Corydoras simulatus occurs more west right? Near the meta? Could they also occur in the llanos?
