The 1st pic looks like a Vieja of some sort.....perhaps a Vieja synspilum
The 2nd pic is of a Sajica (Archocentrus sajica
). The common name for them is "T-Bar Cichlid". That's the name the LFS
normally uses for them...
I'm pretty sure the 4th pic is an Albino Oscar or Astronotus ocellatus "Albino".
I have no idea about the others.....fantastic pics though.
