African cichlid identification

[Irecruitfish]

Does anyone know what type of cichlids these are? The owner said that the blue and yellow one sometimes change colors.

Sorry if the pictures are no good it's been difficult to get pictures since they always hide when I get close to the tank

Could be Pseudotropheus interruptus. Juveniles and females are yellow. Males change to blue and black as they mature.

That does appear to look like them! Although I had four other ones that were humongous but they all passed away. They're like 7 in or so. I'm starting to think if they are just different cichlids. Please take a look at the picture Is this one looks like a smaller version of the larger ones that passed away. They keep hiding but basically it's mouth is more larger and pink than the smaller blue cichlids

Could be a hybrid or just an extremely overfed and therefore abnormaly large specimen. Most Mbuna grow unnaturally large when fed too much.
And with Mbuna it's always difficult if you don't know the source. The market in many countries is flooded with hybrids.
