Reply With QuoteNatural biotope should be white water of Rio Madeira, pH around 6.4-7.4 according to PCF.
What is the natural biotope of a C.pygmaeus?
Can they be put in a blackwater biotope which has little plants? All wood and sandy substrate? pH about 5.5-6.0... kH should be about 1...

White water?
Hmmm... Means lotsa plants...
What corydoras species are found in blackwater?
Never create what you can't control
Interesting question, haven't given much thought about it.
I only know of these species, C. adolfoi, C. bondi, C. blochi, C. osteocarus and Scleromystax sp. C112 (aka Baianinho II). I am sure there should be more.
C. adolfoi is most commonly found in our LFS and Scleromystax sp. C112 (aka Baianinho II) on more than one occassion.
I would think it's clear water with sandy botton rather than black water, anyway it's a wild guess...

The Rio Negro corydoras also includes the C.nijsseni... And apparently, according to Mad Scientist, there is a batch in town!Hope they are not cleared out of the tanks... Another corydoras to add is the C.schwartzi, also from Rio Negro...
From what I read, the only difference between white water and black water is the colour and the pH... Both are low in nutrients, so don't support much vegetation... But because there is alot of decaying matter in the blackwater rivers, the pH is much lower than white water and of course the water more teh-o than the the former...

The usual two places in town which carries a significant number of corydoras species... C328 and TB Ben...
I going down later to check their availability...
Went down to TB Ben to check whether C.nijsseni has arrived yesterday. Sadly, they haven't...
Here's the link by mad scientist for the benefit of all the others who want to play blackwater corys.

But the ones mentioned are mostly difficult to find... Except for C.adolfoi...
Never create what you can't control
Going by that list, C. duplicareus, which looks very similar to C. adolfoi, is seen quite regularly.
C. davidsandsi was here a while ago, and I have seen C. amandajanea at TB Ben as well (as labelled but not verified).
And that means, I have 6 fellas from blackwater region, 4 C. davidsandsi and 2 C. duplicareus.
Actually, how low is your pH?
My current pH which I tested 2 days after setting up the tank was 5.5...
Never create what you can't control
pH range for C. adolfoi is close, from 5.6 upwards. Not sure about C. nijsseni but I have a feeling C. adolfoi may be a lot hardier.
I will see what I can get in the market...
Also considering C.trilineatus... Not exactly a blackwater fish, but whitewater, so conditions are relatively similar just the colour difference...
