Named in honor of Laif DeMason (Homestead, Florida, USA), importer, exporter, and breeder of cichlids.[3]

The color of both sexes is dark blue with black vertical stripes with alternating lighter stripes of light blue to white. Male Demasoni cichlids have egg-spots on the anal fin, while females may lack egg-spots. Males also grows to a larger maximum size than females. Stress coloration is similar to normal coloration but much paler. This species belongs to the so-called Mbuna group of haplochromine cichlids, and like most Mbuna it is highly territorial, with parental care for the offspring (maternal mouthbrooding).
