It's an undescribed species of the Neochromis genus, the fish of this lineage are epilithic algae scrapers, restricted to rocky habitats. Males defend territories while the females are moving in schoals to scrape off the aufwuchs and blue green algae. N. sp. "Bihiru scraper" is a polymorphic species, having one bicuspid and one unicuspid morphs living together in the same rocky substrate. No differences are visible on the females, they both exhibit the same dress pattern. This is a mbipi fish, being quite territorial and aggressive just as the mbunas in the lake Malawi. A minimum 90 gallon tank is required as this fish grows to 14 cm when adult. It lives in sympatry with N. greenwoodi, N. gigas, Mbipia mbipi in the wild but differs in the distribution of the red color on its caudal and anal fin, having more red color than the two above.
