About the species

Petrotilapia sp. "Likoma Barred" is an undescribed rock-scraping mbuna from the reefs around Likoma Island, in central Lake Malawi, recorded at Likoma Island itself, Ndumbi Rocks, and Taiwanee Reef. Its trade name describes a vertically barred colour pattern in breeding males, one of the many locally distinct morphs that make Petrotilapia one of the most taxonomically difficult genera in the lake — a group notorious for multiple, visually different male colour forms occurring even within a single population.
