Id Confirmation And Sexing Help Please

[Skodaman1]

Hi all.

I'm relatively new to mbuna, having had a bunch of fry from Smellyfeet in late April.

Can someone have a look at these 2 pics please.

Having been told that i have greshakei, yellow labs, saulosi and kingsizei in the tank, which is which?

They have also started to colour up a little more recently, and i think i'll need to thin the numbers a little, particularly to sort out the male/female balance. Any recommendations on how to do that?

Thanks

saulosi are yellow/orange males will go blue
kingsizei are light blue with darker blue vertical lines the females will be quite lighter
