Need a website to tell me the difference between male and female pacu fish.?
I have two pacu fish and I don't know how to tell the difference between male and female. One is really big and the other one is just growing, they look different in the nose area, just wanted to know how to tell the difference.
I know they get very big I already have a 250 gallon tank on the way, I am prepared.

Look at the dorsal fin: if it's square, the fish is male; curved or rounded, it's female.
Okay, that means, look at the dorsal fin on the side closest the head. Don't mind the tail side of said fin. You may have to wait until the fish "fronts" - yawns with all fins extended.

there are two ways to tell
1 when they breed
2 cut it open
you cant tell by size or color.
I think you might want to do more thinking on what your going to do with them. Pacus can get 15 to 20 inches in a home tank.
