In which parts of South America do Angelfish live?

Answer 1

Not exactly sure where but.....tropical South America so, warm parts, (but not warmer than 30o C or 86o F [ScienceDirect]), at shallow to medium depths. "They are perfectly colored to hide among roots or other riverine vegetation. They can be found in both white and black water habitats." (The Cichlid Room Companion) "(Fresh water angelfish, genus: Pterophyllum is a small) fish from the family: C(i)chlidae known to most aquarists as simply, "Angelfish". All Pterophyllum species originate from the Amazon River, Orinoco River and Essequibo basins in tropical South America.The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped longitudinally, coloration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All Pterophyllum species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed."
