Hi, all.
I'm curious about the identification of biotopes, not an individual.
Take, as an example, the River Ucayali ... It's a white water river - am I wrong in my assumption that most of the populations (A. panduro, A. bitaeniata A. Agasizi) identified from that region usually do best in clear-water or even black-water conditions, i.e. low conductivity, acid and low suspended minerals?
Are the side streams and even smaller bodies of water of the main rivers not white water? Are the headlands filled with clearwater 'quebradas' in the rain season and after the showers in the remaining year and only the main rivers flow with white water?
Or do the fish from these rivers/rivulets thrive in "soft acidic water" that is what we 'fabricate' for the fish, but this is closer to white-water parameters and we lack the perception of how extreme the conditions are in "true" black-water...
The small tributaries to the typical white-water rivers - are they also white? or are they clear-water?
Answers appreciated - thx in advance.
