Pseudotropheus Saulosi Species Confirmation

Hi All,

upon tank set up I bought a bunch of Juvenile Saulosi which have all turned out to be female. This was about a year ago. About a 2 months ago I was sold a pair of Males or at least that is what I was led to believe under the impression that they aren't fully coloured up yet. The did have the blue and black colouring I was expecting. Since adding to my tank interesting things have happened to the colouration. First about the Tank....

4ft, 90 Gallon, Overstocked for aggression (has been working well), Red Zebras, Cobalt Blues, OB's, Yellow Tail Acei, Joanjohnsonae and the Saulosi, tank boss is the biggest Red Zebra followed by the Male Saulosi in question with third in charge being a Male OB. All in all they a pretty peaceful tolerant of each other..

Back to the Saulosi. a while after being introduced to the tank I notice the bigger of the 2 males began to revert to a more yellow blue colouration with definite black bars especially when on a mission. The sub dominant male becomes very dark. in most cases I have seem the sub-com becomes a lighter shade of blue. he does show the blue and black every now and then but never in the presence of the dominant male. So... the 64million dollar question is... can we confirm from the pictures attached that these fish are in fact male Saulosi perhaps still going through colour change?

Thanks in advance for you thoughts.
