Can Banjo Catfish and Motoro Stingray Live Together?

Possible with Caution

Keeping Banjo Catfish and Motoro Stingray together is possible but requires caution due to differing aggression levels and mismatched flow preferences. Provide a spacious tank of at least 750 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

Banjo Catfish is a peaceful species (1/10), while Motoro Stingray is moderately assertive (5/10). This notable difference means Motoro Stingray may occasionally assert dominance over Banjo Catfish.

Banjo Catfish and Motoro Stingray both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Worth noting: Banjo Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 2–10 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Banjo Catfish and Motoro Stingray together, plan for an aquarium of at least 750 litres with a minimum length of 180 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Sand (Sifters), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Banjo Catfish prefers Low (Still Water) flow while Motoro Stingray needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Both species overlap in the 6–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Banjo Catfish being nocturnal affect compatibility?

Banjo Catfish is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Banjo Catfish during evening hours.
