Can Antennae Stingray and Mokele-mbembe Bichir Live Together?

Antennae Stingray is a moderately assertive species (5/10), while Mokele-mbembe Bichir is moderately assertive (6/10). This modest difference means Mokele-mbembe Bichir may occasionally assert dominance over Antennae Stingray.

Antennae Stingray and Mokele-mbembe Bichir 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: Mokele-mbembe Bichir is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Mokele-mbembe Bichir is a known jumper, so a tight-fitting lid is essential.

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. 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.

To house Antennae Stingray and Mokele-mbembe Bichir together, plan for an aquarium of at least 2500 litres with a minimum length of 240 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), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Plants - Densely covered. Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
