What Does A Cory Home In The Wild Look Like?

[jollysue]

What is the natural environment for a Cory?

Is a single Cory or even 2 or 3 a normal group #?

Is gravel the habitat they have evolved for?

Take A Look At Corys in the Amazon

#2

I feel so guilty!

 

[drewry]

well jollysue

i downloaded a program from this site of the amazon river expodition and watched it today
about differnt species of fish were there were anacondas and kamons and sea snakes
we might not giv them there natural inviroment but they dont have to hide from preditors so we provide a 100% survival rate so dont feel guilty at all

Well said, drewry. I have said the same about my frontosa. They are eaten in their homeland. Nevertheless, we can give them the best and leave the rest.

For some reason that video reminded me of the movie birds .

 

[jollysue]

The Corys are coming!!!!

LOL

That movie must be older than you, Mikaila

We keep getting told that they need really clean water, but look what they live in. Muddy murky nastyness with rotting rubbish!
I understand the water flow has a lot to do with it, but the water that is flowing is nasty...
That really surprised me.

 

[jollysue]

I just figured it is silt.

 

[NottsFishy]

I am surprised by how many there are in that shoal lol

 

[jollysue]

Yeah they are little party animals!

Actually, for a river bed, that water in the first video is exceptionly clean. Notice in the second video, where the water is more murky and slightly tannic, there are less corydoras. The little silt that you see in the first video is the disturbence in the river bed, probably due to mass corydoras movement.

I love the first video. To quote Jurassic Park "They move in herds, they do move in herds..."

Now I am going to sound stupid... What is silt?

 

[jollysue]

silt/Wikepedia


quote from Wikapedia:
"Silt is soil or rock derived granular material of a specific grain size. Silt may occur as a soil or alternatively as suspended sediment in a water column of any surface water body. It may also exist as deposition soil at the bottom of a water body

The main cause of river siltation is erosion from extensive plowing of farm fields, clearcut logging or slash and burn treatment of tropical forests. When the total ground surface is stripped of vegetation, the upper soils are vulnerable to both wind and water erosion. In a number of regions of the earth, entire sectors of a country have been rendered unproductive; for example, on the Madagascar high central plateau, comprising approximately ten percent of that country's land area, virtually the entire landscape is sterile of vegetation, with gully erosive furrows typically in excess of 50 meters deep and one kilometer wide. Shifting cultivation is a farming system which sometimes incorporates the slash and burn method in some regions of the world. The resulting sediment load can cause extensive fish kills, hampering economic development.

"Silt, deposited by annual floods along the Nile River, created the rich and fertile soil that sustained the ancient Egyptian civilization. This silt was depended on for this purpose. A decrease in silt deposited by the Mississippi River throughout the 20th century due to a system of levees has contributed to the disappearance of protective wetlands and barrier islands in the delta region surrounding New Orleans."

I love watching that video, makes me want to get a massive tank and get a huge shoal of corys

 

[jollysue]

Me too! LOL

We had a member with a 100 usg Cory tank

I haven't seen him for awhile. PC something
