Frontosa Care Guide: Keeping the Gentle Giant of Lake Tanganyika
The Frontosa (Cyphotilapia frontosa) is the gentle giant of Lake Tanganyika — a majestic, slow-moving cichlid with bold black-and-white (or blue) banding and the signature cranial hump that old males develop. Calm, long-lived, and surprisingly peaceful for its size, the Frontosa is a true showpiece for a large African setup. Here at Tropical Treasures in Cheyenne, it’s a dream fish for hobbyists ready for a big Tanganyika tank. 🐟
A quick heads-up: we don’t currently stock Frontosa, but we carry a great range of Lake Tanganyika cichlids — ask us and we’re happy to point you to a comparable fish or special-order. Here’s everything you need to know to keep one thriving.
🐋 Frontosa at a glance
Frontosa are large, deep-water Tanganyika cichlids that can reach 10–14 inches and live 15–20 years with good care. They’re slow, deliberate predators that ambush small fish at night, yet remarkably mellow toward tankmates too big to eat. They do best kept in groups (a “colony” of one male with several females). Browse our full African cichlids collection for the Tanganyikans we carry.
📏 Tank size & setup
Because of their adult size, slow swimming, and colony nature, Frontosa need a large tank — a minimum of 125 gallons, with more strongly preferred for a group. Provide a sandy substrate with large rock piles and caves for security. Powerful, reliable filtration is essential for these big, messy eaters. Planning a large display? Our 240-gallon stocking guide is a great place to start.
💧 Water parameters
Frontosa come from the hard, alkaline, oxygen-rich waters of Lake Tanganyika and thrive in temperatures of 76–80°F, pH 8.0–9.0, and hard water. They’re sensitive to poor water quality, so stable, well-buffered, mineral-rich water and strong aeration are key. Always dechlorinate fresh water with a quality water conditioner before water changes.
🍽️ Diet & feeding
As natural predators, Frontosa are carnivores that do best on a high-quality, protein-forward diet. Quality cichlid pellets form a great staple, supplemented with frozen meaty foods like krill, mysis, and silversides. Avoid mammalian protein and feeder fish, which can cause bloat and disease. Feed measured portions — Frontosa are slow eaters and prone to obesity if overfed.
🐟 Temperament & tankmates
Frontosa are peaceful for their size but will eat anything small enough to swallow, so choose tankmates that are too large to be prey yet not aggressive enough to bully them. Other robust Tanganyikans work well. Good companions include Julidochromis marlieri, Leleupi, Brichardi, Caudopunctatus, and Tropheus duboisi — though very small dwarf species may eventually be eaten by adult Frontosa, so plan accordingly. For a bolder predatory cichlid, see our Venustus care guide.
🐣 Breeding
Frontosa are maternal mouthbrooders that breed slowly. In an established colony, a male will spawn with females who then hold the eggs and fry in their mouths for around four to six weeks — a longer brooding period than most African cichlids. Broods are small, and fry are large and hardy. Patience is the name of the game with this slow-growing species.
✅ Is the Frontosa right for you?
If you have a large tank, hard alkaline water, and the patience for a slow-growing, long-lived centerpiece, the Frontosa is one of the most rewarding cichlids in the hobby. New to African cichlids?
