A majestic, slow-moving Lake Tanganyika cichlid with bold black-and-white bars and a domed forehead hump. Long-lived and surprisingly gentle for its size, it is a centerpiece fish for big, deep, hard-water aquariums.

Genus
Cyphotilapia
Part of the African Cichlids
Hardy, vividly colored cichlids from Africa's Rift Lakes (Malawi, Tanganyika, Victoria) and beyond, kept in hard, alkaline, rock-built aquariums. Many are territorial mouthbrooders best housed in robust species-appropriate groups rather than mixed communities.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Sub-adult colony
125 gal / 473 L long
Cyphotilapia frontosa reaches 13–15 in and lives in colonies. 125-gal long is a strict minimum for a sub-adult colony of 5+ (1M/4F); adults need more. Hard alkaline water (pH 8.0–9.0), rockwork caves.

Recommended
Adult colony display
180 gal / 681 L long
Six-foot 180-gal for an adult colony of 5–8, with large rockwork structure, sand, hard alkaline water, strong filtration, and peaceful Tanganyikan tankmates. Slow-growing and long-lived.
Ideal
Tanganyikan biotope
240 gal+ / 909 L+ biotope
8-foot+ Lake Tanganyika biotope with deep rockwork caves, hard alkaline water, sand, and a stable colony. Dignified, slow-moving display fish — best in long-lived setups.

Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Fish eggs are small, translucent spheres, often laid in clutches on plants, substrate, or in a nest — or carried/brooded by a parent in livebearing and mouth-brooding species. A dark eye spot and the curled embryo become visible inside as development progresses.

Fry
Newly hatched fry are tiny and semi-transparent, frequently still carrying a yolk sac that fuels them before they feed freely. They lack full fin structure and adult coloration, staying near cover until they can swim and forage on their own.

Juvenile
Juveniles look like miniature adults but with developing fins and muted or different markings; many species shift pattern and color as they mature. Growth is rapid at this stage given clean water and steady feeding.
Adult
Adults show the species' full size, finnage, and mature coloration, and are sexually mature. Many fish develop sex-specific differences in size, color, or fin shape, which can intensify during breeding.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Frontosa are large, deep-bodied, social fish that should be kept in colonies; an adult group needs a minimum of about 125 gallons (475 L), and bigger is strongly preferred given their adult size and lifespan. Provide hard, alkaline Tanganyikan water: temperature 74-80 F (23-27 C), pH around 8.0-9.0, and high hardness.
In the wild they live at depth over rocky drop-offs, so they appreciate tall tanks, large rock structures with caves, and a calm environment with moderate, gentle flow. Open swimming space combined with substantial caves for retreat suits the colony; dim to moderate lighting echoes their deep-water origins.
Substrate
Use a sand substrate, which suits their digging and the natural rocky-sand bottom of Tanganyika and pairs well with large rock structures. Aragonite sand also helps buffer to the very high pH and hardness they require.
Equipment & setup
Heavy-duty filtration (large canister or multiple filters) is essential for a big-fish bioload, with a reliable heater and gentle-to-moderate flow. Secure, well-supported rock caves give the colony shelter; buffer the water with mineral additives, and CO2/bright lighting are unnecessary.
Diet
A piscivore and carnivore that ambushes smaller fish and invertebrates at night in nature. Feed a high-quality carnivore cichlid pellet plus frozen mysis, krill, silversides, and the occasional earthworm. Avoid feeding live feeder fish or fatty mammalian meats, which risk disease and fatty organ damage; feed measured portions a few times a week as adults to prevent obesity.
Behavior & temperament
Remarkably placid and almost stately for such a large cichlid, frontosa are not aggressive by nature but will eat any fish small enough to fit in their mouths. Keep them as a single-species colony (typically one dominant male with multiple females) or with other large, peaceful Tanganyikans; avoid small tankmates and overly boisterous species. They are slow, deliberate swimmers that establish a calm social hierarchy.
Health
Generally hardy and long-lived, but sensitive to poor water quality given their bioload, and prone to bloat from rich or inappropriate diets. Ich and bacterial infections can appear under stress. Large, stable, hard alkaline water with strong filtration and regular water changes is essential; their long lifespan rewards patient, consistent husbandry, and new fish should be quarantined.
Tips, DIY & hacks
Buy several juveniles and grow them up together to form a stable colony, since adults bond better when raised as a group. They are maternal mouthbrooders that hold for several weeks; their long lifespan means choosing a large, future-proof tank from the start saves costly upgrades.
