Amazonian Angelfish; following the spots

[raglan]

Wild angels, typically what we call scalare, come in both spotted kinds and non spotted.

I understand that Rio Oyapoque or Oyapock in French Guyana is the limit where the Amazonian non spotted kind stops appearing, and further west spotted kinds are found.

It seems possible that the spotted anglels found west of French Guyana were all introduced. some look rather like Peruvians, and some apparently have been found in a Surinam location, with an altumish appearance.

These spotted kinds have been described as some, if not all, introduced, non-native species. in Surinam particularly. Fishbase gives extremely limited information. Here is a mention that scalare in Surinam are introduced

This says that worldwide only a very few incidents of non-native, introduced scalare capture occurred.

Pterophyllum scalare (CTVIER and VALENCIENNES): CICHLIDAE

Native range: Amazon basin

However, "successful" introduction in Guyana might have occurred.

Surinam has angelfish. There are at least several locales where they can be found. Kola Creek is one area that has been mentioned.

Fishbase has some sketchy information and also some apparently completely irrelevant information on this topic of Surinam's angelfish, on Fishbase. Seems they used an immature specimen of an exotic domestic strain to give ( projected ?) scalare morphometrics. http://fishbase.org/physiology/Morph...calare&id=4717


Maybe it would be informative if we could map the spotted kinds' locales . You know, "X" marks the spot .

Here's a map and some information on the main river systems in French Guyana, and mention of the Oyapoque scalare. I have some of them, they are non spotted type, and I have some Rio Negro scalare, which show some dark spotting.

Several kinds of spotted scalare come from Peru.

Those spotted scalare are seldom seen importing into singapore. How about canada?
