Frontosa

Also known as: Cyphotilapia frontosa

Frontosa (Cyphotilapia frontosa) is a large, slow-moving cichlid endemic to the deep waters of Lake Tanganyika. The Frontosa originates from Lake Tanganyika, East Africa, reaches Adult size: 25-30 cm in captivity, typically lives 15-25 years, and is kept at 24-27°C (75-81°F). Individual fish vary, so treat this as a general guide rather than a guarantee.

About the Frontosa

Frontosa (Cyphotilapia frontosa) is a large, slow-moving cichlid endemic to the deep waters of Lake Tanganyika. It is distinguished by its prominent frontal hump, especially in mature males, and its striking vertical black bands on a pale blue to white body. Frontosas are known for their longevity and calm demeanor compared to other African cichlids, making them popular in specialist aquariums. They thrive in stable, alkaline conditions and require spacious tanks with rocky structures to mimic their natural habitat.

Lifespan and health

Frontosas are exceptionally long-lived for aquarium fish, commonly reaching 15-20 years in well-maintained tanks, with documented cases exceeding 25 years under optimal conditions. Their longevity is closely tied to stable water parameters, low stress, and a nutritious diet; sudden fluctuations in temperature or pH can significantly shorten lifespan. Regular monitoring of water quality and prompt correction of imbalances are essential for maximizing their lifespan. Common health issues include bacterial infections (such as fin rot or ulcers) often triggered by poor water quality or injury from tank decorations, and parasitic infestations like ich (white spot disease) especially during introduction or stress. Frontosas are also prone to lateral line erosion (hole-in-the-head disease) if fed a diet lacking in vitamins or if kept in water with excessive nitrates. Preventative care includes quarantining new fish for 4-6 weeks, maintaining nitrate levels below 15 ppm, and ensuring adequate vitamin C and carotenoids in their diet to support immune function and coloration.

Overview

Care and tank setup

Frontosas require a spacious aquarium with a minimum footprint of 120x45 cm (48x18 inches) to accommodate their size and swimming behavior. The tank should feature a sandy substrate and ample rockwork forming caves and overhangs, as they appreciate shaded retreats and use rock structures to establish territories. Avoid sharp decorations that could injure their delicate nuchal hump. Water conditions must be stable: maintain temperature between 24-27°C (75-81°F), pH 7.8-9.0, and hardness of 10-20 dGH. Perform weekly water changes of 20-30% to keep nitrate levels below 20 ppm, as Frontosas are sensitive to poor water quality. Use a high-capacity filtration system rated for at least twice the tank volume to manage their moderate bioload. Feed Frontosas 2-3 times daily with a varied diet: high-protein cichlid pellets as a staple, supplemented 3-4 times weekly with frozen foods like brine shrimp, mysis shrimp, or krill. Avoid overfeeding; offer only what they can consume in 2-3 minutes. While they can be kept with other peaceful Tanganyikan species, avoid overly aggressive or fast-moving tankmates. Suitable companions include other Frontosas (in groups of 6+ to diffuse aggression), peaceful shell-dwellers like Neolamprologus multifasciatus, or medium-sized rock-dwellers such as Cyprichromis leptosoma. Never house them with small fish that may be viewed as prey, or with Mbuna cichlids from Lake Malawi due to differing water needs and temperament.

Adding a Frontosa? Research the species’ adult size and temperament carefully, quarantine new fish before introducing them to your tank, and buy from reputable aquarium stores or breeders.
