Well the blue guy looks like a Metriaclima callainos of some sort. The female red one I can't tell you. (Well I think it is some female, there are way too many of that color to tell.) http://www.cichlid-forum.com/profiles/species.php?id=787 (look at the younger male pictures.)
As for the second one with the color semi showing, seeing has he isn't in his fully dominate color I can't tell you much. My guess is some sort of Melanochromis but I could be really off, it might even be some Cynotilapia afra of some sort, seeing as its head doesn't look as long, though its body seems longer to me. I don't know. Maybe you can find it here: http://www.cichlid-forum.com/profiles/category.php?cat=2
And the last one for some reason I can't recall the name. It isn't a mbuna, and I think it is an Victoria Basin Cichlid but it might just be that it is too young to tell. Look around here: http://www.cichlid-forum.com/profiles/category.php?cat=16 (Maybe a Paralabidochromis of some sort...)
I only needed the first, second and fourth pix ID'd. The third one was a pic of both of them in one pic. Thanks though. But btw, the fish that is the center piece in the third pic is a male saulosi cichlid. Thnx anyways.
They don't really ever show baring but you are saying is is an estherae, which I don't agree with. Though I can't say for sure. If the blue fish ever shows barring than it is the estherae but from looking at it's head and the coloring I really do think it is an Metriaclima callainos. (Assuming it isn't a mix or something.)
Anyways AnDr3w you are the one who gets to decide what it is at the end, seeing as you likley have seen what it looks like in its different temperaments.
