Synodontis decorus is a large Congo Basin catfish with bold markings and an elongated dorsal-fin filament, suited to soft to neutral water.
Compiled by Aquairi from published sources · Published · Updated
Overview
Synodontis decorus is an upside-down catfish native to Cameroon, the Democratic Republic of the Congo and the Republic of the Congo, occurring throughout the Congo Basin except the Luapula and Luvua systems. It is also known as the clown catfish. Total length reaches about 31.8 cm. Adults carry bold dark body markings and an elongated dorsal-fin filament.
Taxonomy
- Family: Mochokidae
- Genus: Synodontis
- Scientific name: Synodontis decorus
- Describer: Boulenger, 1899
Habitat
The species lives in the Congo Basin, including Pool Malebo and the Ubangi and Kasai drainages, and the Lukuga River up to the Kisimba-Kilia rapids. FishBase lists a temperature range of 23–27 °C and pH of 6.0–8.0 for its freshwater, benthopelagic habitat.
Tank requirements
- Minimum tank volume: 350 L
- Temperature: 24–28 °C
- pH: 6.5–7.5
- GH: 5–15 °dGH
- Adult size: 25–30 cm
- Lifespan: 8–15 years
Diet
Synodontis decorus is omnivorous, with a trophic level near 2.9. The genus consumes insect larvae, algae, gastropods, bivalves, sponges, crustaceans and fish eggs. A varied prepared and frozen diet suits the aquarium, offered once daily.
Compatibility
A peaceful but large, nocturnal, bottom-dwelling catfish. It is housed with similarly robust tankmates and given caves and dim lighting. Very small fishes are unsuitable companions for a fish of this size.
Breeding
The species is oviparous and shows distinct pairing during breeding. Aquarium breeding is rarely reported.
Conservation status
IUCN Red List: Least Concern, assessed 16 February 2009.
Synodontis decorus Breeding Guide
Overview
Synodontis decorus is native to Cameroon and both Congos, found throughout the Congo Basin except the Luapula River system, including Malebo Pool. It reaches a maximum length of about 31.8 cm. Common names include clown catfish, clown synodontis and clown squeaker.
Spawning Behavior & Trigger
No spawning observations specific to Synodontis decorus are available. For the genus, spawning is reported during the flooding season between roughly July and October, with pairs swimming in unison, often coinciding with the rising water of the rainy season.
Egg & Fry Care
No documented egg or fry-rearing data exists for this species. Reproductive knowledge for Synodontis is largely confined to egg counts obtained from gravid females, so no rearing procedure can be described.
Common Challenges
The lack of an established spawning trigger is the central difficulty; the species also attains a large adult size. The brood-parasitic strategy seen in the Lake Tanganyika cuckoo catfish (Synodontis multipunctatus) does not apply to this riverine Congo Basin species.
