About the species

Pseudotropheus crabro, the bumblebee or hornet cichlid, is a stocky mbuna endemic to Lake Malawi, instantly recognized by its bold yellow body crossed with dark-brown to black vertical bars. It leads a double life: by day a scrupulous parasite-picker that removes the fish-louse Argulus africanus from the skin of the giant catfish Bagrus meridionalis, and by night — or whenever the catfish breed — a brazen egg thief that darkens its own coloration to near-black, blending with the cave substrate just long enough to raid the very nests it had cleaned.
