The only thing I can say is "yes, they are female Aulonocara". Which exact species? No idea. Most Aulonocara females look very similar (in some cases even the same), and it's near impossible to tell them apart. At least not for me
Yes they are females aulonocara and for the body shape I would say that they are from the stuargranti family, but quite difficult to say the specific specie.
