Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

This is one of the most outgoing and playful Synodontis species available in the hobby. When kept in a proper group, they are constantly active, chasing each other playfully around the rockwork. They are entirely peaceful towards other species and mostly ignore their tankmates. Their bold, diurnal nature makes them a highly entertaining and interactive fish to observe.

Diet

Omnivore

Synodontis lucipinnis is a micro-predator and scavenger that greedily accepts most offered foods. A staple diet of high-quality sinking carnivore pellets and granular foods is ideal. This should be supplemented with regular offerings of frozen or live foods like bloodworms, daphnia, and brine shrimp. They will also graze on small organisms living among the rocks and substrate.

Sex ratio

Harem

They are highly gregarious and should absolutely be kept in groups of at least five or six individuals. A specific male-to-female ratio is not required, as they do not display harem-like behavior or severe intraspecific aggression. Keeping them in groups makes them significantly bolder and more active during the day. Solitary individuals will often hide constantly and pine away from stress.

Feeding frequency

Twice daily

Feeding them small amounts once or twice a day is recommended. They are enthusiastic eaters that will boldly come out of hiding when they smell food in the water. Unlike many other catfish, they are often active during the day, making feeding easier to observe. Ensure food actually reaches the bottom before faster mid-water fish consume it all.

Bioload

This dwarf species produces a relatively low bioload compared to its larger Synodontis cousins. Despite their small size, they are active and have healthy metabolisms, so standard filtration is necessary. Maintaining pristine water quality with regular water changes is essential to emulate their natural Lake Tanganyika habitat. A well-oxygenated, clean environment prevents stress and disease.

Flow

Stagnant

Originating from the rocky shores of Lake Tanganyika, they appreciate moderate to high water flow. Strong water movement ensures high dissolved oxygen levels, which they strictly require to thrive. Powerheads or strong filter return flows are highly recommended in their aquarium setup. However, they must always have access to calm, rocky crevices where they can rest out of the current.

Reproduction

Oviparous

Unlike the cuckoo catfish, S. lucipinnis are simple egg-scatterers and do not parasitize cichlid broods. They breed by scattering their eggs in tight rocky crevices or among marble substrates in breeding setups. The parents will eagerly eat their own eggs if given the chance, so separating them is crucial for a successful yield. Raising the fry requires excellent water quality and very small live foods.

Compatibility & tankmates

They are extremely peaceful and make excellent tankmates for a variety of hard-water setups. They do perfectly well with Lake Tanganyika cichlids, such as Neolamprologus or Julidochromis species. Due to their small adult size, they should not be housed with very large or aggressive predatory fish. They are entirely safe with most robust invertebrates and similarly sized community fish.

Tank level

Middle/Bottom

They are strict bottom dwellers that rarely leave the lower third of the water column. Their behavior is intimately tied to rocky structures, where they spend their time exploring every nook and cranny. They are remarkably adept at navigating tight spaces and often rest completely upside down under rock ledges. An aquarium with a large footprint and complex rockwork is ideal.
