The frontosa is a stately, slow-moving deepwater predator from Lake Tanganyika, famous for its blue-and-white barred body and the large nuchal hump of mature males. It is a long-lived, peaceful-for-its-size giant best kept in spacious species or colony tanks.

A large cichlid reaching 25-35 cm (10-14 in); dominant males develop a pronounced cranial hump (nuchal hump).

Part of the Cichlids
Cichlids are a large, behaviorally complex family of freshwater fish prized for color, intelligence, and elaborate parental care. They range from peaceful dwarfs to highly territorial Rift Lake and Central American species, and most demand stable water chemistry and thoughtful tankmate selection.
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.
Photo coming soon
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.
Natural
representative
Six-bar (Burundi) frontosa
The classic widely available form with six vertical black bars, collected historically from the Burundi (northern) end of Lake Tanganyika. Six- and seven-bar morphs of true C. frontosa are now regarded as the same species.
representative
Seven-bar (Kigoma) frontosa
A seven-barred morph of C. frontosa restricted to the Kigoma area on the east coast; morphometric studies treat it as conspecific with the six-bar Burundi form despite the extra bar.

Blue Zaire / Kigoma deepwater forms
Prized deep-blue geographic variants from the southern half of the lake. Many of these blue Zaire/Kalemie-type fish are now classified as the separate species Cyphotilapia gibberosa (described 2003), though they are still traded under the frontosa name and command premium prices.
Habitat & enclosure
A large fish needing a large tank: a colony of adults requires roughly 450 L (120 gal) or more, with footprint (length and depth) more important than height. Provide tall rock structures and caves mimicking the deep rocky drop-offs of Lake Tanganyika. Water parameters: temperature 24-27 C (75-81 F), pH 8.0-9.0, hardness very high (GH 12-20, KH 14-20). In the wild they live at considerable depth and prefer dimmer, cooler-leaning conditions.
Substrate
Fine aragonite or coral sand suits both their digging behavior and the need to buffer water hard and alkaline. A sand bed also shows off their coloration. Build secure, tall rockwork on the base glass or a support plate so structures cannot be undermined and toppled by large adults.
Equipment & setup
Powerful, oversized filtration (large canister or sump) is essential for the heavy waste of large carnivores. A robust heater kept toward the lower end of the range, strong but not turbulent flow, and excellent surface oxygenation. Subdued lighting is appreciated given their deepwater origin. A secure lid prevents jumping and a large water-change schedule keeps nitrate low.
Diet
A carnivore and ambush predator that feeds on smaller fish and invertebrates in the wild. In captivity offer a high-quality carnivore/cichlid pellet, frozen mysis, krill, and shrimp; whole frozen silversides for adults. Avoid feeder fish (disease and thiaminase risk) and mammalian meats. Frontosa have slow metabolisms and should be fed modestly to prevent obesity and bloat.
Behavior & temperament
Calm, deliberate, and relatively peaceful toward conspecifics of similar size, making colony keeping (one dominant male with multiple females) ideal. They are, however, opportunistic predators that will eat any fish small enough to swallow. Maternal mouthbrooders with relatively large eggs and fry. Generally shy when young, becoming bold and personable adults; an observation fish, not handled.
Health
Hardy and very long-lived when given pristine, hard alkaline water and space. Susceptible to bloat from overfeeding or protein excess, and to ich and parasites if stressed by poor conditions or warm temperatures (warmer water lowers oxygen and stresses this cool-deepwater species). Slow growth is normal; do not push with heavy feeding. Quarantine new arrivals.
Tips, DIY & hacks
Buy a group of juveniles and grow them out to let a natural hierarchy form, keeping a ratio of one male to several females. Plan for their eventual large adult size from the start. Keep temperatures on the cooler side (24-25 C) for longevity and color. Pair only with robust Tanganyikan tankmates too large to be eaten, such as larger Cyprichromis kept as dither or appropriately sized companions.
