Microsynodontis batesii 1 - (Microsynodontis batesii) — 1-2cm

Overview

Microsynodontis batesii, known as Bates' Microsynodontis, is a rare and peaceful upside-down catfish from West-Central African river systems that brings fascinating nocturnal behaviour to specialized community aquariums. Available for sale UK through Tropical Fish Co, this distinctive mochokid reaches approximately 10cm and offers experienced aquarists an opportunity to keep a genuinely uncommon species. Its peaceful temperament and moderate care requirements make it suitable for dedicated fishkeepers willing to provide appropriate water conditions and nocturnal feeding regimes. The species represents excellent value for collectors seeking authentic African river fish beyond the standard hobby offerings.

Appearance and Identification

Microsynodontis batesii displays the characteristic Synodontis body plan but with more delicate proportions befitting its Microsynodontis classification. The body shows elongated form with prominent adipose fin and forked caudal fin. Coloration typically consists of mottled grey-brown to darker charcoal tones with irregular patterning providing effective camouflage against leaf litter and woody substrates. Three pairs of barbels extend from the mouth region, with maxillary barbels being particularly long and highly sensitive for nocturnal foraging. The ventral surface is lighter than dorsal regions—an adaptation seen in many catfish that spend time inverted beneath surfaces. Dorsal and pectoral fins are equipped with sharp spines capable of locking into defensive positions and producing characteristic squeaking sounds.

Natural Habitat

This species inhabits freshwater rivers throughout Cameroon, the Democratic Republic of Congo, and Gabon—part of the Congo River basin drainage system. These tropical rivers feature soft, slightly acidic water stained with tannins from decomposing organic matter. Substrates typically consist of fine sand, leaf litter, and submerged wood creating complex three-dimensional habitat structure. Flow varies from gentle to moderate depending on location and season, whilst overhanging riparian vegetation creates dappled lighting conditions. The aquatic environment is rich with invertebrate fauna living among detritus—the primary food source for this carnivorous catfish. Water clarity varies seasonally, with rainy periods bringing turbid conditions whilst dry seasons concentrate fish in clearer permanent pools.

Aquarium Setup

Provide a minimum 80-litre aquarium with fine sand substrate to protect delicate barbels during foraging behaviour. Furnish generously with driftwood arranged to create caves, overhangs, and inverted surfaces where the catfish can rest in characteristic upside-down posture. Add dried botanicals such as Indian almond leaves, oak leaves, or alder cones to release beneficial tannins, promote biofilm growth, and replicate the leaf-litter habitats of African rainforest rivers. Subdued lighting suits this nocturnal species—use floating plants or surface cover to diffuse illumination. Filtration should provide gentle to moderate flow without creating excessive current, maintaining excellent water quality whilst avoiding stress from turbulence. Live plants compatible with soft water such as Anubias, Java fern, and Cryptocoryne species complement the biotope setup.

Water Parameters and Quality

Maintain temperatures between 22-27°C, with 24-26°C being optimal for long-term health and activity. Water should be soft with pH 6.0-7.5 and low hardness (2-8 dGH), replicating the naturally soft conditions of African rainforest rivers. Ammonia and nitrite must remain at zero, with nitrates kept below 20ppm through regular 25-30% weekly water changes. This species appreciates slightly tannin-stained water created through botanical additions, which also has beneficial antimicrobial properties. Dissolved oxygen should be adequate through gentle surface agitation—whilst not a rapids species, good oxygenation supports metabolic health. Avoid drastic parameter fluctuations, as stability is more important than hitting exact target values.

Feeding and Carnivorous Diet

Microsynodontis batesii is a carnivore that naturally feeds on aquatic invertebrates, insect larvae, and small crustaceans encountered during nocturnal foraging. In captivity, provide a varied sinking diet: high-quality carnivore pellets or meaty wafers form the daily staple, supplemented 4-5 times weekly with frozen or live foods including bloodworms, blackworms, daphnia, brine shrimp, and other small meaty offerings. Feed after lights-out or during evening hours when nocturnal activity commences—this ensures the shy catfish receives adequate nutrition without competition from more aggressive diurnal feeders. Target feeding near hiding areas using a feeding tube can help ensure proper intake. Avoid relying on flake foods which rarely reach the substrate before being consumed, and ensure food is appropriately sized for the catfish's relatively small mouth.

Behaviour and Nocturnal Habits

This peaceful catfish is predominantly nocturnal, spending daylight hours sheltered within caves, beneath wood, or resting inverted under broad leaves. As dusk approaches, activity levels increase significantly, with the fish emerging to patrol substrate and décor searching for food. The species exhibits classic upside-down swimming posture when navigating underneath surfaces—an adaptation that allows feeding from inverted positions and possibly offers anti-predator advantages. They are non-territorial and can be kept singly or in small groups if aquarium space permits. Occasional squeaking sounds may be heard when the fish are handled or during competitive feeding interactions, produced by articulating pectoral spine joints. Movement is typically deliberate and methodical rather than frenetic.

Compatible Tank Mates

Microsynodontis batesii thrives alongside small peaceful community fish that occupy mid to upper water levels. Excellent companions include small African characins such as African tetras or Congo tetras, peaceful rasboras, and small non-aggressive barbs. Other gentle bottom dwellers such as smaller Synodontis species or peaceful loricariids can coexist provided adequate floor space and retreats are available. Avoid housing with large aggressive cichlids, particularly territorial substrate-spawners that might trap the catfish in defended zones. Similarly exclude notorious fin-nippers and highly boisterous species that would outcompete the shy catfish during feeding. Very small fish under 2cm should also be avoided, as they might be consumed during nocturnal hunting expeditions.

Breeding

Captive breeding of Microsynodontis batesii is uncommon and poorly documented, with few reliable accounts of successful spawning in home aquaria. Like other mochokid catfish, breeding likely requires excellent water quality, mature specimens, and environmental triggers such as increased protein feeding followed by cooler, softer water changes mimicking seasonal rainfall. A separate spawning aquarium with appropriate caves and spawning substrates offers the best prospects. Eggs would likely be deposited in sheltered locations, possibly with male guarding behaviour, though specific reproductive strategies for this species are not well established. Fry would initially require microscopic live foods such as infusoria and paramecium before graduating to newly hatched brine shrimp and microworms as they develop.
