CichlidFish.com - Fish That Think.

I have a 125 g cichlid tank in it's beginning months. I have 5 yellow labs and 2 Kenyi Cichlids. When I purchased the Kenyi's I had 2 girls and 1 boy. One girl died in a bacterial bloom. As that cleared up my other female began to morph on me from blue, to yellow. She used to be a pale blue, more pale than her counterpart, but had no yellow. She is much larger than the yellow male, is still not a full yellow like him but is still the pale blue with strong hints of yellow..... so what is he/she? He/she is a digger, is certainly the dominant person in the tank which indicates male to me, but.... he/she should have changed colors by now, right? I might add that although small and faint there appears to be an egg spot showing up... but it's no where near the size, brightness or clarity as the yellow guy.
I have a few pictures of the tank and one where his/her face is visible but it is hard to get him/her to take a good photo that captures the color variances.what!?

Probly a male, from what I've heard the males start off blue, then change to yellow, but I've also heard of older females turning yellow.
Also you need to add some more fish, Kenyi are super aggresive.
