Labeotropheus
Algal-grazing cichlids endemic to Lake Malawi, popular in aquariums.
Labeotropheus is a genus of cichlid fish found only in Lake Malawi, East Africa. The genus contains at least 11 species, many of which have subspecies or local variants; scientists still need more research to settle the exact number. These fish are popular in the aquarium trade and do well in cichlid-specific tanks. Like many Malawi cichlids, they feed by grazing on algae. They require hard, alkaline water, like all Lake Malawi cichlids. An aquarium of at least 120 liters (31.5 gallons) is recommended, decorated with rocks or terracotta pots to create caves.

Lore & Background
Labeotropheus species are algal grazers, like many Malawi cichlids. The genus is endemic to Lake Malawi in eastern Africa and currently includes at least 11 recognized species, with additional subspecies or races noted. Taxonomic work remains incomplete, leaving the exact number of species uncertain. The genus includes species described as early as 1926 (Labeotropheus fuelleborni) and as recently as 2023 (several species by Pauers and Phiri). Notable species include Labeotropheus trewavasae, described in 1956, and Labeotropheus chlorosiglos and Labeotropheus simoneae, both described in 2016.
Reader's Guide
Labeotropheus are popular ornamental fish ideally suited to the cichlid aquarium. Like all cichlids from Lake Malawi, they are best maintained in hard, alkaline water. The aquarium should be decorated with rocks, although caves can also be easily created from terracotta pots. These fish are best kept in aquariums with volumes greater than 120 L (31.5 gallons). Their significance lies in their endemic status to Lake Malawi and their popularity among aquarists, though further taxonomic work is needed to clarify the number of species. The genus includes at least 11 recognized species, each with subspecies or races, reflecting ongoing scientific investigation into their diversity.

Frequently Asked Questions
What is Labeotropheus and where does it come from?
Labeotropheus is a genus of cichlid fish native exclusively to Lake Malawi in East Africa. It belongs to the family Cichlidae and is well known among hobbyists as a group of algae-grazing, rock-dwelling species.
How many species of Labeotropheus are there?
Scientists currently recognize at least 11 species within the genus, though the exact count remains uncertain because several species have subspecies or local variants that are still being sorted out through ongoing research.
What water conditions do Labeotropheus require in an aquarium?
Like all Lake Malawi cichlids, Labeotropheus need hard, alkaline water to stay healthy. They are not suited to soft or acidic setups and will thrive best in a cichlid-specific tank maintained at those parameters.
What do Labeotropheus eat and how do they feed?
These fish are primarily algae grazers, using their mouths to scrape biofilm and plant material off rocks and surfaces. In captivity they can be supplemented with algae wafers and other plant-based foods to mirror their natural diet.
What tank size and decorations work best for keeping Labeotropheus?
A minimum volume of 120 liters (about 31.5 gallons) is recommended to give the fish adequate swimming and territory space. Adding rock piles or terracotta pots to form caves helps replicate their natural rocky habitat and reduces aggression between individuals.
