Mat, you forgot 2 other items: patience and talent!
I just re-read Linke's introduction of the species. In it he doesn't list any species found with them except half-grown Discus. This is hardly surprising because the water values were extreme: muddy, blackwater pH 3.9, dGH & dKH <1, 8 µS/cm @ 29.8°C. You could check Fishbase for the lower Rio Madeira and see what occurs there.
I don't think it is a scientific paper, because Apistogramma sp. "Abacaxis" isn't scientifically described.Mike is het possible that you send me his paper, Or can tell me the title so i can find it on google scholar?

Good thing i can read German. Thanks a lot Mike!He is the article that introduces the species: Linke, Horst. 1999. Apistogramma sp. „Wilhelmi" - eine neue, farblich interessante Art aus dem Apistogramma agassizii-Formkreis. Das Aquarium, Nr. 361, Juli 1999. pp. 22-26. It's in German, of course.
It isn't a scientific paper, it is an article in the magazine "Das Aquarium", (Nr. 361, Juli 1999. pp. 22-26.)Can someone send the link to the german article? I can't find it on Google Scholar!!
You can't really interpret the pH in the normal manner. This is water with hardly any ions, of any description. In really soft water pH isn't a very useful measure, and is inherently unstable.Very nice pics and fish. If these fish like a pH of 3, what pH are you maintaining them at? What are you doing to lower pH?
Vinegar runs between pH 2.0-3.0. I've only seen pickled herring in that stuff.
I'm not sure how you would obtain a copy the article, it may not exist in an electronic version.
