Nyassachromis sp. 'eucinostomus yellow' South East Arm
Genus: Nyassachromis
Biotope: Open sandy areas in shallow water (35 m or less) throughout the South East Arm of Lake Malawi.
Geographic distribution: South East Arm of Lake Malawi, recorded both south and north of Monkey Bay.
Typical adult size: Up to 10 cm total length.
Sexual dimorphism: Females and non-breeding males are silvery. Ripe males have a black snout, bright yellow opercula, and a bright yellow margin to the anal fin.
Special notes: Distinguished by a relatively pointed snout and 10 lower gill rakers. Differs from related forms in gill-raker counts and snout shape. Occurs commonly in shallow sandy habitats of the South East Arm and formed 8.3% of fish biomass in experimental trawls at depths of 30 m or less south of Monkey Bay, and 2.5% north of Monkey Bay. In 1990–91 members of the N. eucinostomus complex accounted for less than 0.5% of midwater trawl bycatch.
