Help me ID these cichlids

Hi,

Please help me ID these fish. I took the pics using my cell phone while at my local pet shop. They got these cichlids, they are labeled as African Cichlids (National), so I suppose that they are locally breed (I'm in Panama, Central America). They are approx. 2 inches long. Sorry for the low quality pics.

Here are the pics:

Thanks in advance.
