Lake Malawi Synodontis Care Guide
Synodontis njassae is the only Synodontis endemic to Lake Malawi, a nocturnal catfish well matched to mbuna and other rift-lake cichlids.
Compiled by Aquairi from published sources · Published · Updated
Overview
Synodontis njassae, the Malawi squeaker, is an upside-down catfish endemic to Lake Malawi and the only Synodontis species native to that lake. Total length reaches about 19.2 cm. It appears in the aquarium trade and forms a minor component of local commercial fisheries.
Taxonomy
- Family: Mochokidae
- Genus: Synodontis
- Scientific name: Synodontis njassae
- Describer: Keilhack, 1908
Habitat
The species lives in Lake Malawi, where it is found among rocks during the day and moves around the area at night. FishBase reports a pH of 7.5–8.2, hardness of 20–30 dH and a temperature of 20–23 °C for the lake habitat, which is hard and alkaline.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24–28 °C
- pH: 7.5–8.5
- GH: 10–20 °dGH
- Adult size: 12–15 cm
- Lifespan: 8–15 years
Diet
Synodontis njassae is omnivorous, with a trophic level near 3.1. It feeds on insects, crustaceans and other invertebrates in the lake. In the aquarium it accepts a varied diet of prepared and frozen foods, offered once daily.
Compatibility
A peaceful, nocturnal, bottom-dwelling catfish that pairs well with Malawi mbuna and other rift-lake cichlids. It is not a schooling species. Caves and rockwork provide daytime shelter; small tetras are unsuitable companions.
Breeding
The species is oviparous with distinct pairing during breeding. Aquarium breeding is rarely reported.
Conservation status
IUCN Red List: Least Concern, assessed 20 June 2018.
Synodontis njassae Breeding Guide
Overview
Synodontis njassae is endemic to Lake Malawi and is the only Synodontis native to that lake. It grows to a total length of about 19.2 cm and forms a minor component of local commercial fisheries while also entering the aquarium trade. The IUCN Red List classifies it as Least Concern.
Spawning Behavior & Trigger
No species-specific spawning observations are available. For the genus as a whole, spawning is reported during the flooding season between roughly July and October, with pairs swimming in unison; this general pattern has not been confirmed for Synodontis njassae.
Egg & Fry Care
There is no documented account of egg or fry development for this species. Reproductive knowledge across the genus is largely limited to egg counts taken from gravid females, so no fry-rearing method can be described.
Common Challenges
The absence of a known spawning trigger and rearing method is the main obstacle. Although Lake Malawi cichlids share the habitat, the brood-parasitic strategy of the cuckoo catfish (Synodontis multipunctatus of Lake Tanganyika) is not documented for Synodontis njassae.
