Overview
The two-ray banjo catfish is a secretive, slow-moving catfish that spends the daylight hours buried in soft substrate with only its eyes showing. It suits keepers with a little experience.
Caring for the two-ray banjo catfish
Give the two-ray banjo catfish a tank of at least 30 gal (112 L) with a deep, soft sand or silt bed. Add plenty of leaf litter and driftwood, and keep the light dim and the flow gentle.
Keep the water warm and soft, at 73 to 82°F (23 to 28°C) and a slightly acidic pH of 6.0 to 7.5. After dark, feed meaty sinking foods such as frozen bloodworm, chopped prawn and sinking pellets. Leave the food where it can find it.
It is peaceful and will not chase tank mates. It feeds at night and is easily out-competed, so choose a quiet tank and make sure food reaches it. It is best kept on its own, and it has not been bred in home aquariums.
Good to know

In the wild
The two-ray banjo catfish lives in the lowland Amazon basin, over soft mud and leaf litter in slow, tannin-stained water. It surfaces on its own schedule after dark.
