thay are different. they look different. blacks get twice the size.

all adult pacus look the same to me.

how can you tell them apart?

it seems the red disapears as they get old and then they looks like a black

They're similar in appearance. But, the black has no red in the abdomen and is deeper bodied (the head looks proportionately smaller).

Left - Piaractus brachypomus - red-belly pacu - to 24"

Right - Colossoma macropomum - black pacu - to 36"

so can the babys be told apart or do they both have red bellies?

 

[Oddball]

The black is infrequently sold. The reason you see a lot of young pacus available with red bellies is because they're the 24" red belly pacu from commercial farms.

Does anyone know why we don't get yellow belly pacu, the caranha, (Piaractus mesopotamicus)? I bet there is a market for them, they only get to 16" and are mainly fruit and nut eaters.

that sucker is cool lookin and i WANT ONE!

It's hard to say why we don't see these. They exist in greater numbers, in the wild and in aquaculture, than the 2 more common species. Fisheries and sports-fishing sites have this species listed as attaining 21" in length and 25lbs. Still a tank-buster species.

THE TRUE MONSTER OF MONSTERS!!!!
