Poll's Synodontis Care Guide
Synodontis polli is a Lake Tanganyika endemic catfish with a spotted olive-brown body, suited to spacious tanks with Tanganyikan cichlids.
Compiled by Aquairi from published sources · Published · Updated
Overview
Synodontis polli, Poll's synodontis, is a catfish endemic to Lake Tanganyika in East Africa. It has an olive-brown back covered with large irregular black spots, a lighter underside, white barbels and dark triangles at the bases of the rayed fins. It is a member of the squeaker catfish family, Mochokidae.
Taxonomy
- Family: Mochokidae
- Genus: Synodontis
- Scientific name: Synodontis polli
Habitat
The species is endemic to Lake Tanganyika, with records from the Democratic Republic of the Congo, Burundi, Zambia and Tanzania (Wikipedia). It inhabits rocky coasts in the littoral zone at depths down to about 20 metres. The lake maintains stable temperatures of 22-26 °C and an alkaline pH around 8.5-9.
Tank requirements
- Minimum tank volume: 250 L
- Temperature: 24-27 °C (75-81 °F)
- pH: 7.8-9.0
- GH: 10-20 °dGH
- Substrate: sand
- Lifespan: 8-15 years
Diet
The species is an omnivore. In the wild it feeds on algae scraped from rocks and on small invertebrates (Wikipedia). In the aquarium it benefits from a varied diet of sinking dried foods, frozen and live items, offered when activity peaks in dim light.
Compatibility
Poll's synodontis is a peaceful, mostly nocturnal bottom-dweller that benefits from caves and subdued lighting. It is compatible with most Tanganyikan and other African cichlids and similarly sized tankmates, while very small fish that could be eaten are best avoided.
Breeding
The species is oviparous and shows distinct pairing during breeding (FishBase). Wikipedia notes that spawning likely occurs during the July-October flooding season, though the reproductive habits of most Synodontis species remain poorly documented; captive breeding is considered advanced.
Conservation status
IUCN Red List: Least Concern (assessed 2025), per FishBase.
Synodontis polli Breeding Guide
Overview
Synodontis polli, Poll's Synodontis, is endemic to Lake Tanganyika (and possibly Lake Mweru, unconfirmed), per Seriously Fish. Note that, although the knowledge-base record labels it a cave-spawner, the consulted source describes it instead as an egg scatterer; this guide follows the source. Breeding has not been recorded in captivity, so reliable spawning detail is limited.
Sexing
Seriously Fish notes sexing is challenging in this smaller Synodontis; the main distinction is that mature females are rounder in the belly than males.
Conditioning
Seriously Fish reports the species readily takes frozen, live and dried foods, but unusually for the genus most individuals refuse vegetable matter. A varied protein-rich diet supports condition; the Tanganyikan habitat means hard, alkaline water.
Breeding Setup
Reflecting its rift-lake origin, Seriously Fish gives water of 24-28 °C, pH 7.5-8.5 and hardness 15-35 °H. Provide a sandy substrate, rocky cover and hiding places. As territorial disputes can occur during establishment, give groups enough space and structure.
Spawning Behavior & Trigger
Seriously Fish describes S. polli as an egg scatterer that shows distinct pairing during spawning, with limited wild data available. Because captive breeding has not been recorded, no reliable aquarium trigger can be stated, and claims of cuckoo brood-parasitism for this species are not supported by the consulted source.
Egg & Fry Care
Because breeding has not been recorded in captivity, detailed egg and fry care for S. polli is not documented in the consulted sources, and is therefore omitted rather than estimated.
Common Challenges
The principal challenges are the absence of recorded captive spawning, the difficulty of sexing this small species, and territorial behaviour during group establishment. Stable hard, alkaline Tanganyikan conditions are essential.
