Synodontis ornatipinnis 4 - (Synodontis ornatipinnis) — 4-5cm

Overview

The Synodontis ornatipinnis, commonly known as the Ornate Synodontis or Barfin Synodontis, is a striking african catfish for sale UK native to the Congo Basin in the Democratic Republic of the Congo and Zambia. This peaceful upside-down catfish grows to around 22 cm in captivity and displays ornate fins with intricate patterning. Its engaging nocturnal behavior and manageable temperament make it a prized addition to spacious community aquariums housing robust, non-aggressive tankmates. At Tropical Fish Co, we supply healthy juveniles that adapt well to aquarium life and reward attentive care with years of active, fascinating behavior.

Appearance and Coloration

Synodontis ornatipinnis displays a mottled brown and cream base color with darker blotches and fine spotting across the body. The most distinctive feature is the ornate dorsal fin, which is enlarged and sail-like with prominent dark banding and spots. The pectoral and pelvic fins are similarly decorated with intricate patterning. The caudal fin is deeply forked with dark banding. The body is robust and slightly compressed, with a broad head, prominent eyes, and long sensitive barbels. Under subdued lighting, the ornate fin patterning is particularly striking. Juveniles display similar patterning to adults, with the dorsal fin becoming more pronounced as the fish matures.

Natural Habitat and Distribution

This species inhabits the Congo River basin, favoring slow-moving tributaries, deep pools, and areas with submerged logs and rocky outcrops. The water is typically warm (23–27 °C), neutral to slightly acidic, and well-oxygenated. Synodontis ornatipinnis is primarily nocturnal, hiding among submerged logs, rock crevices, and dense vegetation during the day. At dusk, it emerges to forage for small invertebrates, insect larvae, and organic debris, often swimming upside-down beneath floating plants or overhanging branches. The natural environment is dimly lit with moderate current and abundant hiding places. Replicating these conditions at home encourages natural behavior and optimal health.

Aquarium Setup and Décor

A 300-litre aquarium is the minimum for a single adult Synodontis ornatipinnis or a pair. Use soft sand or fine gravel as the substrate, and provide plenty of caves, driftwood, and rock formations to create secure hiding places. Live or artificial plants can be used; robust species such as Anubias, Java fern, and Vallisneria are preferable. Subdued lighting is essential to reduce stress and encourage natural behavior. A secure lid is mandatory, as Synodontis are strong swimmers and may jump. Ensure all décor is stable and free of sharp edges. Provide multiple hiding spots to reduce territorial stress, especially if keeping more than one specimen.

Feeding and Nutrition

Synodontis ornatipinnis is an omnivore with a strong carnivorous tendency. Offer a varied sinking diet based on quality catfish pellets or wafers, supplemented with frozen or live foods such as bloodworms, brine shrimp, daphnia, and chopped earthworms. Include some vegetable matter such as blanched courgette, spinach, or spirulina-based foods to aid digestion. Feed once daily in the evening, as this species is primarily nocturnal. Ensure food reaches the substrate and is not consumed entirely by faster mid-water fish. Overfeeding can lead to poor water quality, so remove uneaten food after 30 minutes.

Behaviour and Social Structure

The Ornate Synodontis is peaceful and can be kept singly or in small groups if space permits. It is primarily nocturnal, hiding during the day and emerging at dusk to forage. One of the most fascinating behaviors is the tendency to swim upside-down beneath floating plants, driftwood, or the aquarium lid, using the barbels to search for food on the underside of surfaces. When startled, it may produce audible squeaking or croaking sounds by grinding the pectoral fin spines. Despite its size, it is a gentle and non-aggressive species, though it may consume very small tankmates.

Compatible Tank Mates

Ideal companions include peaceful medium-sized cichlids (severums, firemouths, Geophagus), large tetras (Congo, Buenos Aires), barbs (tinfoil, rosy), rainbowfish (Boesemani, turquoise), and other peaceful Synodontis species. Avoid housing with very small fish or fry, aggressive fin-nippers, highly aggressive territorial cichlids, or tiny shrimp and other small invertebrates. Fast-moving, mid-water species that will not be harassed or outcompeted for food are best.

Breeding in the Aquarium

Breeding is uncommon in home aquaria and may require a large, mature setup with seasonal water changes and excellent conditioning on live and frozen foods. Like many Synodontis, spawning is not fully documented in captivity. Sexual dimorphism is subtle; females may be slightly larger and plumper when carrying eggs. If breeding is attempted, provide multiple caves and monitor water parameters closely. Spawning may occur after a series of partial water changes that simulate seasonal flooding. Fry, if produced, require specialized care and micro-foods such as infusoria or liquid fry food initially.
