Banjo Catfish Care Guide - Habitat, Feeding & Breeding

The Banjo Catfish has an unusual, flattened body with a broad, wedge-shaped head and a tapering tail. Its mottled brown colouring closely resembles dead leaves, bark and shadowed stream debris, making it exceptionally difficult to spot when resting on the bottom. Small barbels around the mouth help it investigate the substrate in darkness.

This is a peaceful, secretive and predominantly nocturnal catfish. During daylight hours it often lies motionless or buries itself beneath sand and leaf litter, emerging after dark to search for food. Its stillness and camouflage are central to its survival, rather than signs of illness or inactivity.

Banjo Catfish are members of the family Aspredinidae, a South American group known for distinctive body shapes and cryptic habits. They are not closely related in appearance to the more familiar armoured Corydoras catfish, although both are peaceful bottom-dwelling aquarium fish.

In nature, these catfish live among submerged leaves, twigs and soft detritus in quiet waters. Their nocturnal lifestyle allows them to forage while many larger predators are less active, and their leaf-like form helps them disappear into the forest-floor environment.

Banjo Catfish are native to tropical and subtropical parts of South America, including the Amazon and Orinoco drainage regions. They inhabit slow-moving streams, forest pools and quiet margins where leaf litter and soft sediments accumulate.

A single Banjo Catfish should have an aquarium of at least 80 litres, with a footprint around 90 x 30 cm or larger preferred over a tall, narrow tank. Use soft sand or another smooth substrate that allows natural burrowing, and provide driftwood, rounded wood, caves, dried leaves and subdued lighting. Gentle water movement, shaded retreats and open areas of soft bottom mimic its quiet natural habitat, while a secure lid is advisable because individuals may wander at night.

Up to about 15 cm (6 in) in total length. Females are usually broader-bodied and may grow slightly larger than males.

Banjo Catfish are opportunistic carnivores that feed mainly after dark. Offer sinking carnivore pellets or tablets supplemented with frozen or live foods such as bloodworms, brine shrimp, daphnia, blackworms and chopped earthworms. Place food near their hiding areas after the aquarium lights go out so it reaches them before more active tankmates consume it.

Banjo Catfish are peaceful and can share an aquarium with similarly peaceful South American community fish, including small to medium tetras, pencilfish, peaceful rasboras, Corydoras and non-aggressive small cichlids. They should not be housed with boisterous or fin-nipping species, highly aggressive cichlids or large predatory fish. Very small fish and newly hatched fry may be at risk if they can fit into the catfish's mouth, particularly after dark.

Banjo Catfish are rarely bred in home aquariums, although spawning has been achieved in suitable setups. A mature group can be conditioned with plentiful live or frozen foods, followed by a large water change with slightly cooler, soft water. Spawning generally takes place among leaf litter or other cover, with the eggs scattered over the substrate. The eggs and fry require protection from filtration and hungry tankmates, and the tiny young need appropriately sized foods once free-swimming.

Females are generally fuller and broader through the body, especially when mature, while males tend to be slimmer. The differences are subtle, so reliable sexing is easiest with adult fish viewed from above.
