Frontosa Cichlid
Cyphotilapia frontosa
The 'Gentle Giant' of Lake Tanganyika. A massive, majestic cichlid (up to 35 cm / 14 inches) famed for its stark white body, thick black vertical stripes, and the colossal, bizarre hump on the forehead of older males. It is a slow, nocturnal deep-water predator that requires massive, dimly-lit aquariums, where it rules with calm elegance.

Species description
Geographical Origin and Habitat: Lake Tanganyika, endemic. Inhabitant of great depths: rarely encountered above 15 meters (50 ft), densely populating the submerged rocky walls down to -50 meters (-165 ft) in almost total darkness.
Taxonomy and Morphology: Frontosa (Cyphotilapia frontosa). Iconic and mastodontic cichlid, with an incredibly developed nuchal profile that gives it its characteristic frowning and imposing appearance.
Social Behavior: Regal and "slow" cichlid. Doesn't get agitated like other Africans; prefers to glide over the rocks in colonies (harem: 1 giant male and 4-6 females). Peaceful with conspecifics outside the mating season, intolerant of frantic movements.
Coloration and Sexual Dimorphism: Spectacular bright blue/white base coloration with 6 conspicuous vertical black bands. The frontal hump (Gibbosity) is present in both sexes but the adult male (Alpha) develops a literally titanic nape and prolonged fins.
Care, breeding and tankmates
Aquarium Setup: Huge aquariums (at least 500 liters / 130 gallons, 150-200 cm / 60-80 inches in length). Being deep-water fish, they hate strong light. Use dim lamps, large rocks offering tunnels to hide in, and very fine coral or calcareous sand.
Diet and Feeding: Piscivorous/Carnivorous. In nature they feed mainly on Cyprichromis, which they hunt at dawn before they wake up. In the aquarium offer large pellets of excellent quality, shelled shrimp, mussels, fresh silversides. No mammal meat.
Water Quality: Very rigorous: very hard, super-alkaline water (pH 8.5) and enormously stable. Water changes must not cause sudden fluctuations, which Frontosas suffer from impressively, reacting with prolonged loss of appetite.
Compatibility and Cohabitation: Any fish under 7-8 cm (3 inches) in length will sooner or later disappear into their large mouth during the night. Ideal with calm large Tanganyika Cichlids or giant Loricariids resistant to hard waters.
Aquarium Breeding: Mouthbrooders, low fecundity. The female lays large eggs and incubates them (maximum 20-40) for 3-4 weeks. The mother, due to her huge mouth, can involuntarily swallow the eggs in case of panic.
Risks and Diseases: Hyper-susceptible to "Malawi Bloat" (occlusion) if overfed. Terrible sensitivity to trauma: panicked males in small tanks, crashing into the walls, can die of a heart attack or seriously injure themselves.

Fish profile
- Temperament
- Semi-aggressive
- The Frontosa is generally a gentle giant, possessing a calm and deliberate demeanor. They are relatively peaceful towards fish they cannot swallow but will assert dominance over their own kind. Their peaceful nature makes them highly susceptible to stress if housed with fast, nippy, or aggressive tank mates.
- Diet
- Omnivore
- In the wild, they are piscivores that ambush sleeping fish at dawn and dusk. In the aquarium, they should be fed a high-quality, protein-rich diet consisting of large sinking cichlid pellets, krill, pieces of white fish, and earthworms. Avoid feeding them live feeder fish due to the risk of introducing diseases.
- Life expectancy
- 15-25 years
- Cyphotilapia frontosa is an extraordinarily long-lived fish that can easily live between 15 and 25 years in an aquarium. Reaching this milestone requires consistent care, oversized filtration, and high-quality nutrition. Maintaining the chemical and physical stability typical of Lake Tanganyika is essential to prevent chronic diseases over the long term.
- Adult size
- 35 cm
- The catalog's scalar value is 35 cm. The FishBase SPECIES table (v25.04 snapshot) source reports a maximum adult measurement of 33 cm for this species, recorded as total length (TL). The taxonomic record consulted is Cyphotilapia frontosa (v25.04); male or unsexed record. These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
- Sex ratio
- Group
- Frontosa should be kept in groups, ideally with a ratio of one male to three or four females. Males can be aggressive toward one another, and in all but the largest aquariums, only one dominant male will typically thrive. Providing multiple females helps spread out any breeding-related harassment.
- Feeding frequency
- Twice daily
- Adults have a relatively slow metabolism and only need to be fed once a day or even every other day. Juveniles require more frequent feedings, about twice a day, to support their growth. Overfeeding adults can lead to obesity and poor water quality, so portion control is important.
- Bioload
- The Frontosa Cichlid grows to an enormous size and consequently produces a very heavy bioload. Massive biological filtration and a highly efficient mechanical filtration system are absolutely necessary for a group of adults. Very large, regular water changes are required to keep nitrate levels low and maintain the hard, alkaline water of Lake Tanganyika.
- Flow
- Stagnant
- They originate from deep, calm waters in Lake Tanganyika and prefer slow to moderate water flow in the aquarium. Strong currents will force these large, slow-moving fish to expend unnecessary energy and cause them stress. A gentle turnover rate that still provides adequate surface agitation for oxygenation is ideal.
- Reproduction
- Oviparous
- They are maternal mouthbrooders, but breeding can be slow as females take years to reach sexual maturity. Spawning occurs stealthily on the substrate, after which the female scoops the large eggs into her mouth. The incubation period is long, lasting up to 4-5 weeks, yielding a small number of very large fry.
- Compatibility & tankmates
- Despite their size, Frontosa are relatively peaceful but will opportunistically swallow any fish small enough to fit in their surprisingly large mouths. They are best kept in a species-specific tank or with other large, peaceful, slow-moving Lake Tanganyika cichlids. Fast, aggressive mbuna should be avoided as they will harass the slower-moving Frontosa.
- Tank level
- Middle/Bottom
- These large cichlids tend to occupy the middle and lower levels of the aquarium. They appreciate large, open caves and overhangs built from smooth rocks where they can retreat and feel secure. They are not highly active swimmers and often spend time hovering majestically near the bottom.
