Dont post often on here anymore (became a little unfriendly sometimes), but i do like a good severum, and i couldn't resist this one.
You've got 3 H.Efastciatus.
Top one looks to be from Tapojos stock, whilst the bottom 2 all look to be from manause stock. All males by the way.
Not Inridia or Notatus im afraid.
Nice looking fish, Seem very happy.
All the best
