File talk:Colossoma-brachypomus.jpg

What fish is this?
The name of the file (Colossoma brachypomus) implies that this is the Red-bellied pacu. However, an editor on that page recently raised concerns that it wasn't, and on the Pacu page, this is described as the Black Pacu. Other wikis use this image inconsistently also. So which is it? If its not a Red-bellied Pacu, please comment at Talk:Piaractus_brachypomus so we know to remove it from there. If it's not a Black Pacu, then the same applies to the Pacu page. --HighFlyingFish (talk) 22:24, 21 February 2018 (UTC)


 * I agree that it looks more like a black pacu, which is of course not red-bellied, but still belonging to Piaractus brachypomus, formerly known as Colossoma brachypomum (Cuvier, 1818)? It seems one way to distinguish those two species is that the name brachypomus comes from rom brachy (= short), and pomum (= operculum), referring to shorter operculum compared to Colossoma macropomum.

 * I have no particular expertise here, but I labelled the image according to the label in the aquarium display — Steven G. Johnson (talk) 15:15, 26 February 2018 (UTC).
