About the species
Otopharynx heterodon, the royal blue hap, is a mid-sized haplochromine cichlid endemic to Lake Malawi, where it ranges the length of the lake along the seam between rock and sand. Males glow metallic blue with a yellow chest; the more sober, three-spotted females do the parenting, brooding eggs in their mouths. It earns its living the unglamorous way — sifting edible particles out of sediment stirred up off the bottom — and its mild temperament has made it a recurring, if cyclical, favorite among Malawi aquarists.
