Buccochromis lepturus
Buccochromis lepturus
A massive, open-water predator native to Lake Malawi. They are pelagic pursuit hunters that will consume any fish small enough to fit in their mouths. Due to their enormous adult size and extreme swimming speed, they require exceptionally large aquariums. They should only be housed with other large, robust Malawi cichlids.

Buccochromis lepturus Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Male
Adult males are spectacular, developing an emerald green or blue metallic sheen and long fin trailing edges. They are aggressively intolerant of other males of the same species and require a strict 1-male rule per tank.
Differs in 3 traits from base species
Also known as: Show Male, Green Lepturus
Female
Females remain slightly smaller than males and retain a silvery-yellow base coloration with a prominent dark diagonal stripe. They are less aggressive than males and can be kept in small harems if the tank is large enough.
Differs in 2 traits from base species
Also known as: Wild Type
Juvenile (Grow-out)
Sold at typical retail sizes (3-4 inches). They will grow rapidly. You must be prepared to upgrade to a 150+ gallon (560L+) 6-foot aquarium within their first year to prevent stunting. Even as juveniles, they will hunt smaller tank mates.
Differs in 5 traits from base species
Also known as: Unsexed Juvenile, Baby Hap
Buccochromis lepturus Care Guide Summary
The Buccochromis lepturus, scientifically known as Buccochromis lepturus, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 40 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.
To thrive, the Buccochromis lepturus requires a freshwater only aquarium with a minimum volume of 560 litres and a tank length of at least 180 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.5–8.8 and a general hardness of 10–25 dGH. A moderate water flow is preferred.
The Buccochromis lepturus is a rewarding species to keep, provided its core environmental needs are met. This species is available in 3 varieties: Male, Female, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Buccochromis lepturus Habitat Setup
When setting up an aquarium for the Buccochromis lepturus, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour.
Buccochromis lepturus Compatibility Notes
Classified as semi-aggressive, the Buccochromis lepturus is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.
Who Buccochromis lepturus Is Actually For
Buccochromis lepturus is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.
The most common mistake is treating Buccochromis lepturus like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Buccochromis lepturus Feeding & Diet Considerations
The Buccochromis lepturus is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and will eat fry, so breeding efforts in the same tank are unlikely to succeed.

Fish Similar to Buccochromis lepturus
Buccochromis rhoadesii
Buccochromis rhoadesii
A massive, apex-predator Haplochromine cichlid endemic to Lake Malawi. They are open-water pursuit predators characterized by an immense mouth and a distinct diagonal stripe across the body. Due to their enormous adult size and strictly piscivorous nature, they require massive aquariums and can only be housed with similarly large, robust species. Any tank mate small enough to fit in their mouth will be eaten.
Malawi Hawk
Aristochromis christyi
A large, specialized predatory cichlid native to Lake Malawi, commonly known as the 'Malawi Hawk'. It has a distinctive laterally compressed beak-like jaw and hunts by tilting forward to ambush prey. It is a formidable piscivore that will swallow any fish small enough to fit in its mouth. Best kept in a large Hap/Peacock setup with similarly sized, robust tank mates.
Malawi Gar
Lichnochromis acuticeps
An elegant, predatory Haplochromine cichlid from Lake Malawi, named for its elongated, torpedo-shaped body and pointed snout. While it is a true piscivore that will hunt small fish, it is surprisingly peaceful toward other similarly sized cichlids. A fantastic centerpiece for a large 'Hap and Peacock' setup.
Trout Cichlid (Champsochromis)
Champsochromis caeruleus
A massive, fast-swimming predatory cichlid from Lake Malawi, often called the 'Malawi Trout' due to its streamlined, torpedo-like body. They are pursuit predators that require enormous tanks with a massive footprint for open swimming. Not highly aggressive for a Malawi cichlid, but their sheer size and piscivorous nature mean they will instantly consume any fish that fits in their large mouths.
Elongatus Cichlid (Pseudotropheus Elongatus)
Chindongo elongatus
The Elongatus Cichlid is a highly active, slender mbuna endemic to Lake Malawi. Formerly classified as Pseudotropheus elongatus, it is notorious for being one of the most aggressive and territorial of all mbuna. They require a strictly herbivorous diet (grazing on algae/aufwuchs) and a large aquarium heavily decorated with rocks to break sightlines. Due to extreme conspecific aggression, they are best kept in harems (1 male to 4+ females) or in a carefully planned, overstocked mixed-species mbuna tank.
Malawi Eyebiter
Dimidiochromis compressiceps
A large, highly specialized predatory cichlid endemic to Lake Malawi. Named for its legendary habit of biting the eyes out of prey (though it mostly swallows smaller fish whole), it features an extremely compressed body used to camouflage among reeds before ambushing its target. Males turn brilliant metallic blue, while females remain silver.
