That's what I figured, he has a bunch of colors he turns and being 20" you sure notice him alot. Thankz ~ZP3R3 said:Black PACU
I knew it was his mood. It's to many colors because of diet.(always the same)Fish can change they colour. It depends on their diet and their mood.
DUDE!!that's a red bellied pacu.
NOT a black pacu. major difference about a black pacu is, first of all, they are RARE. they have a protruding lower jaw, and surprisingly, they are NOT all black in coloration! they are more greenish on top and black on the bottom with a MUCH elongated body.
