I'm not sure exactly what species of compressiceps I have been seeing in the stores. The lower of the two images from the link below looks like the ones I have been seeing.
Yup, that one is Dimidiochromis Compressiceps, also known as the 'Malawi Eye-biter". They are a large preditor, and need a very large tank with fish that are large enough not to be eaten - there prey is the mbuna and peacocks that are so popular.
