Need Fish ID Help! Please!

I'm thinking an elongatus (Pseudotropheus elongatus) based on body shape...I also think I spy an auratus in the fourth pic from the top in the above post...checking a few pics out will get back.

Yep, that is definitely an auratus. I've identified a lot of my fish, but the blue zebra type of one has eluded me. It's color can look just about the same as the one I posted of the original posters fish, but then gets dark like the pictures I posted. It's also an extremely quick fish and slow growing. It is only a couple inches long and the other fish I got at the same time that were the same size are now 3 to 3 1/2 inches long.
 
Ok, this shows its color a little bit better, although it's stripes can almost totally disappear too. Just took this picture and took the others an hour or so ago when the aquarium lights were out.

Are its fins the same bright blue colour that shows up in the photo ?
 
The fins are light colored, with shiny blue areas that show up in the light. There are also shiny blue areas on it's cheeks. They sort of shine like patches of glitter. This is also a very peaceful fish, usually the one being picked on not the one doing the picking. It has gotten very good at hiding, but when it's out and about it can outrun anything in my tank with ease.
 
http://www.aquariacentral.com/forums/member.php?u=71393jbcs80, I didn't intend to hijack your post, but I was wondering if your fish is the same as mine. The last picture I posted looks a lot like the one you posted, but it's hard to tell with pictures sometimes! Is yours timid or aggressive? How big is it approx?
 
She looks very similar. Her fins aren't colorful like yours though. She is very timid and has been knocked up a few times over the past 4 months. I haven't really noticed any stripes but she does have a small reflective colorful area near her gills.
