is this a pacu or silver dollar

[joshc21]

does anyone know if this is a pacu or silver dollar? i have 4 of them that came with the tank but i can’t figure out what king of silver dollar it is and now i kind of think it’s a pacu, does anybody know for sure?

Does not appear to be a pacu. Common silver dollar

Looks like a metynnis altidorsalis (one of the common silver dollar species).

One of the biggest tells for pacu is the black on the tail that even juveniles have and a much fuller profile.

Look like my spotted silver dollars

Definitely Metynnis maculatus. Not pacu.
M. altidorsalis wouldn’t be spotted, and in M. Lippincotianus the spots would be larger, eye-size.
Can see one male, the others are not shown complete. Do you want to keep them, or are you trying to rehome them?
