Paros do not always come in black water before, paludicola for example, alfredi and rubrimontis occurs in clear water, and certainly a few other species. [/quote]
[quote=”Bernd Bussler” post=3559]Well, I have alfredi trapped in a large creek with clear water, I look at home if I still have a habitat photo of it. No idea whether there are also black water alfredi, but the habitat in Sedilli is clear water and rather have a small river than a creek. [/quote]
Hello, Bernd,
I think these data that you give about the water parameters P. alfredi, rubrimontis and paludicola live in according to your experiences urgently need confirmation.
In the species category here on the website of the PP you can read that the type localities of alfredi and rubrimontis are blackwater habitats.
P. rubrimontis:
Linke found low pH values (between 3.5 and 4.5) and an extremely low conductivity (only up to 20 micro Siemens/cm) in the original habitat, a typical black water creek, which was very dark coloured by humic substances.
It is strictly recommended for rubrimontis to see to very similar water conditions according to their original habitat. I think it might be dangerous to raise confusion about the water parameters they really need. There’s a great difference between the “clear water creeks” you report and the “very dark blackwater creek” the species description speaks of. So this needs to be clarified – for the sake of the fish.
P. alfredi:
type locality with black water of pH 4.5 to 5.0. Standard breeding conditions for Paros.
According to our species description here only P. paludicola doesn’t necessarily depend on real blackwater conditions and will not resent being kept in soft, acid clear water (but still not totally without humic substances) – due to the fact that some forms indeed are found in clear water creeks whereas others are blackwater inhabitants like almost all other paros.
