Can Motoro Stingray and Red Tailed Black Shark Live Together?

At a Glance
Behaviour & Temperament
Motoro Stingray is a moderately assertive species (5/10), while Red Tailed Black Shark is semi-aggressive (7/10). This modest difference means Red Tailed Black Shark may occasionally assert dominance over Motoro Stingray.
Motoro Stingray and Red Tailed Black Shark 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: Red Tailed Black Shark is a known jumper, so a tight-fitting lid is essential.
To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Motoro Stingray and Red Tailed Black Shark to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.
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 6.5 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 5–10 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.
Tank Setup
To house Motoro Stingray and Red Tailed Black Shark together, plan for an aquarium of at least 900 litres with a minimum length of 180 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.
Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
