Fuelleborn's Cichlid

Geographic Origin and Biotope: Lake Malawi (Endemic). Exclusively frequents exposed rocky coasts ("Upper Rocky" habitat with high turbulence), swimming close to the cliffs to graze algae among the crashing waves.

Taxonomy and Morphology: Fuelleborn's Cichlid / Mbuna (Labeotropheus fuelleborni). Powerful cichlid with a unique morphology: very protruding, almost fleshy snout ("Tapir nose"), and inferior mouth positioned under the head like in loricariids.

Social Behavior: Rough and hierarchical Mbuna. Highly territorial, never detaches from the rocks it constantly patrols. Dominant males are aggressive and will relentlessly chase females and rivals.

Coloration and Sexual Dimorphism: Extreme polymorphism. The standard male pattern is electric blue with dark blue vertical stripes. Females are often "OB" (Orange Blotch) or "O" (pure Orange). There are spectacular Marmalade Cat and Thumbi West variants.

Aquarium Setup: Spacious Malawi tank (min. 120-150 cm / 48-60 inches). Decor consisting of huge round boulders stably stacked to create primary caves. Intense lighting to promote algal growth essential to its diet. Very strong water flow (Wavemakers).

Diet and Feeding: Hyper-specialized herbivore. Uses its rasping snout to tear tough algae (Aufwuchs). In the tank it absolutely needs flake or sinking pellet food rich in Spirulina and low in animal protein. Absolutely no food for carnivores.

Water Quality: Needs the typical hard and alkaline water of the Rift (pH > 7.8, high KH). Extremely intolerant of nitrates; surface turbulence must guarantee oxygen saturation.

Compatibility and Tankmates: Compatible only with other robust Mbunas (Metriaclima, Pseudotropheus, Melanochromis) of different coloration. It is recommended to keep it in a harem (1 male and 3+ females) to dilute its amorous arrogance.

Aquarium Reproduction: Maternal Mouthbrooder. The male attracts the female to the sand nest, after spawning the female collects eggs and sperm in her mouth. Incubates for about 21-28 days then releasing 20-30 fully formed fry.

Risks and Diseases: Malawi Bloat. Its curse. If fed with tubifex, bloodworms or discus pastes, its very long herbivorous intestine will go into lethal occlusion, killing it in excruciating pain.
