A striking African catfish famous for its 'cuckoo' breeding strategy, where it sneaks its eggs into the clutches of mouthbrooding cichlids. They are highly active, social, and thrive in hard, alkaline water typical of Lake Tanganyika. They must be kept in groups to diffuse conspecific aggression and are best kept with Rift Lake cichlids.

Standard
The standard adult form. Requires a large footprint tank and a group of at least 4 to establish a pecking order without singling out individuals for bullying.
Differs in 1 trait from base species
Also known as: Adult, Wild Type
Juvenile (Grow-out)
Young Cuckoo Catfish typical of commercial sale sizes. They will eat constantly and grow fast. Must be moved to a large, hard-water setup as they mature.

Cuckoo Catfish Care Guide Summary
The Cuckoo Catfish, scientifically known as Synodontis multipunctatus, belongs to the Catfish family group. Adults reach a maximum size of approximately 25 cm and have a depressed 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 high level of biological waste.
To thrive, the Cuckoo Catfish requires a freshwater only aquarium with a minimum volume of 340 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.5–9 and a general hardness of 10–25 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Cuckoo Catfish is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard 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.
Cuckoo Catfish Habitat Setup
When setting up an aquarium for the Cuckoo Catfish, 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, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.
Cuckoo Catfish Compatibility Notes
Classified as semi-aggressive, the Cuckoo Catfish is a social species that requires the company of its own kind to thrive. When choosing tankmates, 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.
Cuckoo Catfish Feeding & Diet Considerations
The Cuckoo Catfish will eat fry, so breeding efforts in the same tank are unlikely to succeed and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.

Duboisi Cichlid (Tropheus)
Tropheus duboisi
An iconic Lake Tanganyika cichlid famous for its dramatic life-stage color change. Juveniles are jet black with brilliant white polka-dots, while adults develop a blue head and a distinctive yellow or white vertical band across a dark body. They are highly aggressive toward their own kind and must be kept in large colonies (10+) to disperse aggression. They are strict herbivores that require a specialized diet to avoid fatal digestive issues.
African Jewel Cichlid
Hemichromis bimaculatus
A strikingly beautiful but notoriously aggressive West African riverine cichlid. Unlike the alkaline-loving Rift Lake cichlids (e.g., Mbuna), Jewel Cichlids prefer neutral, softer water parameters. They are renowned for their brilliant red breeding dress and iridescent blue spots, but also for their extreme territoriality, especially when forming pairs and spawning. They are avid diggers and will uproot most plants.
Frontosa
Cyphotilapia frontosa
A majestic and iconic deep-water cichlid from Lake Tanganyika, famous for its striking black and white bands and the prominent nuchal hump on its head. Despite their massive size, they are gentle giants compared to other African cichlids. However, they are highly effective piscivores and will easily consume smaller fish. They are best kept in a 'harem' colony of one male to multiple females.
Striped Raphael Catfish
Platydoras armatulus
A highly robust, armored catfish native to the Amazon and Orinoco basins. Famous for their ability to produce audible squeaking or grunting sounds when distressed or defending territory. They are nocturnal scavengers that spend most of the day hiding in driftwood or caves. Note: Their rigid pectoral spines can easily become tangled in standard aquarium nets.
Common Pleco
Hypostomus plecostomus
A heavily armored, nocturnal catfish famous for eating algae. However, they grow incredibly large, produce massive amounts of waste, and frequently outgrow standard aquariums. They require driftwood in their diet for digestion. As they age, they may become territorial or develop a taste for the slime coat of slow-moving, flat-bodied tank mates.
Guppy
Poecilia reticulata
One of the most iconic and widely kept aquarium fish. Renowned for their incredible colors, hardiness, and prolific breeding. As livebearers, they give birth to fully formed, free-swimming fry. Males constantly pursue females for mating; therefore, a ratio of at least 2 females per male is strongly recommended to disperse stress.
