Probably Metynnis hypsauchen.

I can confirm M. hypsauchen. Good looking fish; especially the male(-s?).

Okey Thanks guys!
Marc van Arc..can you really see if those are males?
I have no idea who is a male or not!
Can you please tell me whitch pictures are of the male and female?...Thanks

The anal fin of the females is straight while males have a lobed (curved) one. Both sexes have red in the anal fin.
So pictures 1, 4 & 9 show males; so is the lower fish in picture 5. I have my doubts about the fish in picture 7 (with the Apisto); it might be a male as well.
